ac motor speed control

My uncle recently gave me a compact, functional ac motor with an axial blower attached to it. its a pretty cool thing, and i am planning on putting it in my mac's plexi case (when its built). i have no clue how to vary the speed. from what i found on wikipedia, an inductance motor cannot have speed control. how do i know if this motor is brushed or inductive?? and if its brushed, how do i vary its speed? help!!??

AC motor power supply

I have an old Dayton electric motor I pulled out of a lab blower. (I have no idea how old it is, I pulled it out of my grandpa's bottomless basement.) It looks like it still works, but I found it with no wires or anything attached to the terminals. (All of the internal connections look good, however.) So, here's the tricky bit, how do I run power to it? I copied everything off of the label on the motor, and I'll post it on the end. I've got very near to 0$ in the project bank, so the cheapest I can possibly do this the better. I don't need anything nearly as sophisticated as speed control, or anything like that. Here's the info from the label: model: 5K261 HP: 1/3 RPM: 1725 V:`115 A: 5.4 Hz: 60 Time Rating: Cont. Temp. Rise: 48C PH: 1 Frame: 56 Brgs: Sleeve Code: H S.F: 1.35 S.F.A: 6.0 Amb: 40C No.: S60CXCDY-4065 Insul: Class: A Thermally Protected: AUTO I'm not quite sure what I'm going to do with it yet, that depends largely on how well it works.

Need help with AC motor

What is a low cost way of vary a 2 pole ac motor? I know a vfd can handle the job, but I am looking for a way under $100. Also can someone help me out with some wiring. If I have a 120 VAC motor plugged into the wall, how would I reduce the voltage enough to run LEDs off the same supply wire? In other words, I only want to have 1 plug and run a motor and LEDs at the same time. Any help would be greatly appreciated.

AC Pump Motor Not Working? Answered

I have just come across a free pool pump and hope I will be able to get it up and running.  So far I have had absolutely no luck with it.  The run switch seems to work and so I don't think it is the culprit.  I have even tried two newish capacitors which I know work.  When I plug it in it just hums.  It doesn't throw the breaker so I don't think a short is the problem and it isn't bound up as I can turn it easily by hand.  There is also no sign of twitching as the motor attempts to start.  The overpower protection switch seems to be good and shows continuity across all polls.  The motor itself has continuity where I believe it is necessary so I am at a loss for what could be wrong.  The motor says it is good for 115 volts as well as higher but I would prefer not to shove higher voltages through it if not necessary.  Do any of you have ideas on how I could get this up and running as the pump is in excellent condition and will be useful as a runoff booster pump.

recycling broken AC motors?

I love demolishing things for parts. Often a broken AC motor is left over. Usually it contains a decent amount of copper. But the copper is mostly deeply embedded in iron (a core or a ring around it made out of stacked steel plate). Since it has been put inside the iron there must be a method to take it out. Copper prices are very high. If it can be separated quickly without melting the whole thing down, I would consider doing this myself. How?

Will a 240 Volt AC Motor Operate on 120 Volts AC

I need to know if a 240 volt ac squirrel cage fan motor can be safely run on 120 volts ac. An quick internet search reveals several sources that all say no, but I am concerned that the people answering the question don't know what they are talking about - as is often the case on the internet. I know there are a lot of want-to-be engineers out there ready to answer any question posed even when they have no experience or knowledge of the issue. Please do not guess at this or offer some unsubstantiated opinion.  I need a real answer to this question. Here is what I do know about this issue from researching a couple of electrical engineering sites. Lowering the motor input voltage by 50 % does several things. 1) The motor will run slower. 2) The torque developed will drop to about 25% of its full voltage rating.  3) This decrease in torque can make the motor stall when trying to start under a heavy load. 4) There may be drastic speed fluctuations due to load variations.  5) The motor current will double if the load remains constant. I can understand how these issues could cause severe problems in some applications, but perhaps not in the application I am looking at. I want to use a squirrel cage motor rated at 1/20 HP, 240 volts, 0.5 amp in a direct drive fan application. Here is how I am looking at this issue: - I need to reduce the fan speed so the speed reduction is a good thing in my application. - I have test run the motor on 120 volts for about an hour and there is plenty of torque to operate the fan. I figure at the lower speed there is less air load on the fan blades so less torque is required. Again a good thing for this application. The is no heavy load at start up and the motor seems to have plenty of starting torque for the fan. The fan does not reach full speed as fast as it does on 240 volts, but it still does so in about 4 to 5 seconds so this shouldn't be an issue either. Since it is a fan moving air and not some machine moving gears and levers the load is constant so the speed does not fluctuate at all. Again this should not be a problem. The possibility of the motor current increasing is my only concern so far and apparently it is not an issue since a test run showed the current decreased from 0.5 amps at 240 volts to 0.4 amps at 120 volts.That is a significant current drop instead of the predicted increase. Since this is a fan, I think the current decreases because the load decreases with the lower speed. For these reasons and based on my apparently successful test run I think the motor will operate fine on the decreased voltage. However, I am not sure how to factor the motor slip into this. Slip is the difference between the synchronous and asynchronous speed of an induction motor. From what I have read the slip will increase dramatically when the voltage is cut in half, but I am not sure what physical affect that will have on the motor. If you know what effect that will have or know of some other factor I am not catching please let me know.

Use AC voltage to control an AC relay

I have an obsolete device with a bad controller (all potted with plastic, of course), where instead of delivering 120VAC to the motor, it gives only 55VAC.For a workaround, I was wondering if I could somehow plug a relay in place of the motor, and then use it to switch 120 right from the wall to the motor.Most relays I've seen are like 5-12VDC, so would I have to get some kind of transformer, or is there a cleaner approach?

16 V AC POINT MOTOR?

Hi there, I would like to say hi to the instructables members for a start. Hi! I have always enjoyed reading from this site and I see that there is a lot of help in the topics posted here. I am a Computer Technician that now wants to play in the hardware game (Are you all enjoying Windows 10?). So I'm starting small with an arduino and the raspberry pi, (not side by side yet,) a few motors, servo's, 7" color crystal display, and other things that I have salvaged from stuff or found cheap. I have a few of these CD drive eject motors with lil' knobs I was reading this post about how to make an electric magnet as I am trying to manually make my own point motor for my model train set.  For those in and not in the know, here is some information about what I am trying to do. Create 2 electric magnet coils that pull or repel a nail or metal bar where an upright pin ~2-4 mm is able to travel a distance of ~6-8mm (oo Gauge) in order to change a track piece from one position of a "junction point" to the other, allowing the train to change track or take another route. I would like to try and do this myself as I have plenty of different types of gauge wire, dpdt's (for pole switch?), nails or metal bars(to act as middle pin maybe and bar to be pulled back and forth), diodes (for bridge rectifier) , resistors (to calm the voltage down if I have to as I think it will get rather warm else), a constant power supply (16V ac admittedly)  and plenty of BABY BABY small yet rather strong.. magnets..etc.. ( BTW These were taken from a motor that was inside some water speakers, for perfect reasons the motor had a spin disc attached to it with 3 very small magnets, then in the water compartment there is a spin disc with more magnets attached and a wirly-gig to create the siphon to jettison the water up when the music is played so I now own 60 of the little blighters, (that's if i need them at all to be honest I'm a little lost in this idea))  So please take me as a n00b and please help me in going about this. Yes I could go buy one, but what does that achieve, when I believe I have everything I need at my fingertips and I wish to learn. I presume I will need to deal with the constant AC in order to be able to make a switch to change the polarity of the two coils in order to pull or repel the magnet or nail in either direction to then move the tracks junction from one line to another. I'm going to try and make some coils, in some rather thin wire that is insulated.  Thanks again for any replies. EOL

Green Motor

Hey, i am not good at electronics, but heres the idea: i have "planned" an energy saving motor. Anyway there would be a motor, say, driving a bike. The on the wheel's gear we could put another motor, which is for producing electricity. I am not too sure, but i think it produces AC current. But we need DC to drive the first motor (the one moving the bike). So hook up an AC to DC converter to the second motor (the one producing electricity). Then hook some diodes to the wires connecting the first motor from its power source. I think the wires going out from the power source needs diodes, too, since it allows current to flow in one direction (technical term called forward biased? ). To prevent the first motor driving the bike from "burning", a voltage regulator and a current regulator should be needed, right? That's basically the plan. I would be glad to be corrected if i got anything wrong. Thanks.

General knowledge about working with an AC motor? Answered

can you control an AC motor's speed? Answered

I have a <1hp motor that i'm currently trying to turn into a homemade chopsaw. one of the problems i'm running into is that the motor is spinning too fast for the blade to handle. The idea is that i would use a triac with the gate connected inline with a capacitor that was connected off of one of the ac mains line. the hope was that i could control how much of the waveform the triac chopped off by setting the capacitance of the capacitor to some level where about 3/4 of the way through the cycle it would stop triggering the triac cutting off the end of the wave. is this a possible method of managing the speed of an ac motor or am i setting myself up for heartache and pain in the form of a dead motor? UPDATE: i underestimated the max speed that the chop saw blades are capable of, there's a large enough margin of safety that i'm not worried about overspeeding at all, i will leave this question up because it was answered so concisely and maybe it will help someone else out on their journey. look forward to the chopsaw instructable!

Motorized Futon?

I'm not sure if this is the right forum, but I was just tryin' to see if I can find some help for some questions I have.The basic story is soon my brother's moving back into my house, limiting me to one 9x10 room rather than the two I have now. I wanted a futon, but I like building things and creating things, so I thought I'd build my own. Then I thought I could motorize it.The concept is the same concept as the automatic windows on many modern cars. Press the button once, the motor goes until it's at the end, and a relay switches and it stops. Simple enough, right?I'm just not sure which parts to use. I saw this, and thought it'd be enough. I think I did the math and it's something like 150-ish pounds per second [torque](referance: http://www.surplusgizmos.com/Oriental-115v230v-AC-125-HP-Induction-Motor_p_110-1473.html )I'm not sure if that's too strong or not strong enough-- or if it'd even work!Now, I already have the design all set out, I know how I can get the futon to work, and the tracks and everything. For the relay, I was thinking of putting 2 metal plates at each end of the track, attaching the metal plates to springs, so once the motor pushes against it, it hits a relay and shuts the engine off.I'm just not really sure how to do any of this. Not really sure what relays I need or anything like that. Any help would be nice. :D

Not sure where to find a 60 to 120 rpm AC motor

I'd like to add a small motor to a hand cranked coffee grinder (Hario Skerton Coffee Grinder).  It's conical burr style grinder that produces a consistent particle size (much more so than the mini blender, whirlly style grinder).  I'll expand on why that's important when I build the thing.   My problem is that is takes 10 minutes or so to grind enough coffee for two people. I'd like to put a motor on it.  I tried spinning it with a battery powered drill, but the RPMs were too high.  The burr spun faster than coffee beans could feed.  I'd like a motor in the 60 to 120 rpm range.  I still need to determine the torque required.  Additionally, I'd like to plug this right in to a 110 outlet.  Does anyone have a suggestion on an appliance I could scavenge or the type of motor I should look to buy?   Thanks, Mike

brushed induction motor confusion? [answered] Answered

My father and I are currently restoring a metal-working lathe, however, we do not have 3 phase power to power the original 0.5HP 3 phase motor. We do, however, have a slightly smaller 0.25HP motor. At first appearance, it seemed to be a simple AC/DC brushed motor with a field and winding on the armature. There was no wiring diagram supplied with it, but in one configuration (what appeared to be the ameuture and field coils) are wired in parallel for 120V operation. This did not seem right, since the field coils will be simply shorted across the mains, but I assumed that since we are dealing with AC and inductors, this is OK. It works flawlessly, but reversing the polarity of either the fields or armature would cause the motor to sit and buzz. If started manually, it took off slowly but sounded awful. I need the motor to rotate in both directions and do not have enough materials to do this mechanically. On closer inspection after dismantling the motor, it appears there are 4 brushes, connected together in 2 pairs. They are not directly connected to anything. The 4 wires coming out seem to be just for wiring both field coils in either series of parallel for 110V and 220V operation respectfully. Perhaps even more strange, the 4 brushes are mounted on a centripetal switch, which disengage the brushes from the armature. I was able to make out on the rust that it said "revolution induction motor." So I reasoned out that after the fields are energized, it will induce an electrical current in a few of the coils on the armature, and the energy would flow to the other 2 sets of brushes, causing a different set of coils on the amature to energize and this would initially start the motor. After it gets going, the switch disconnects all the brushes and the motor operates as a simple induction motor. My father used to rebuild motors for a small company, and this is in fact one of the motors he repaired. Although he is skilled at this practice, he does not understand the operation of induction motors and can only figure out wiring by strictly following a diagram or trial and error. I am curious about what this type of motor even is, and how it works! In th meantime, I will research induction motors and how they work, and see what I can learn.

The hoist also has a limit switch.  I would like to be able to specify 15 up/down movements of the hoist that can be repeated. My question is how can I do this? Any comments are greatly appreciated. Please see the attached images of the limit switch and the toggle switch. The toggle switch includes a large capacitor which is just shown on the right side of the photograph.
