I want to make a baby night toy with multi color LEDs and a rotation device. For which i need a low speed motor. Can someone help me find such a motor or give any idea on how an ordinary motor can be used for this purpose? thanks in advance for all the feedback.

Find a use for two small motors that plug in and work great want to find a use?
I'm working on a project that needs a certain RPM of motor. I am looking at motors from http://servocity.com/html/3-12v_gear_motors.html. I will be running these motors at ~5v. Is there an equation I can use to calculate this sort of thing?

Hi, I am a ME with very limited knowledge on electrical side of the world. I have ordered a electric motor from Germany with 240 V assuming it will be single phase. The motor has rocked up with 230 V winding but 3phase connections. Is there any chance I can connect this motor to our single phase supply??? Any device which will help to use this motor. Please help.

Could you pick up any current from the magnetic field of the motor and feed it back into the motor?

Hi, how can I control the main motor from SATA pins directly? The point is just simply make it spin. Like this: http://www.youtube.com/watch?v=ZTSFZ7pQfNY ...or if someone can explain what bridges to make in circuit itself.

hi , my question is what would happen if i connected a simple motor ( 3v ) to an AC power supply of the same volt ? will the motor keep turning in both directions right and left .. and so on ? if yes , how can i convert a 3v DC to AC ? and how to control the speed ? coz i need an idea to make a power circuit that can make a simple motor do so (turn right and left and right and left and so on ..... in a controllable speed ) , can you help me?

So here is my situation, i plan on building (https://www.instructables.com/id/Beginners-guide-to-building-Arduino-robots-with-Bl/) and i was about to order all the parts and i wondered, why there are so many types of gear motors! my current understanding is the higher "1st" digit (ex 1000:1)means the motor is more accurate and precise and slow. So does that mean one with a low number first (ex 10:1) would be faster? please tell me if i am wrong. So i would like a FAST gear motor for my robot, could anyone post me a link to a good fast gear motor. Much appreciated!!!

I want to rotate a stainless steel shaft that is in a vertical position having a 40 mm diameter and 300 mm length. The motor will be attached to the bottom of the shaft, so when the motor is turned, the said shaft will rotate. The shaft is not driving anything, it just turns on its own. The shaft's mass is 3kg(according to my calculations). I want the shaft to rotate at an angular speed of 45 degrees per second. Having this information, how can i size the motor that will do the job. What kind of torque would i need, what kind of wattage. Please show me some calculations so I can know how motor sizing is correctly done. Very much appreciated, Chris

Hi all,I have been given a treadmill motor by a friend, sadly none of the control boards have come with it, just the motor and a transformer bolted to the same bracket.I'm hoping someone can tell me the best way for a layman to hook this up for variable speed, as I would like to improve on my 1/4hp single phase motor currently attached to my lathe.I don't know much about the motor and could not find a datasheet, but a pic is attached.Is there any plug and play options that don't cost the earth, ideally i would like to be able to plug it into the mains (UK) and just control with a pot.As always thanks in advance, you guys make this place a great resource for us noobs.

I'm a novice with motors, so would appreciate some help and advice. I envision a project with two blocks of wood side by side. Just a couple of 12 inch wood squares, for example. I want to rotate each individually, though to different degrees and at different increments. The first block should rotate 90 degrees at 15 second intervals. The second block should rotate 180 degrees at 30 second intervals. How would you recommend i accomplish this? what motor would you recommend? must i use a microcontroller and a step motor? I have some experience with arduino, but wondering whether there is a simple circuit or a simpler mechanism of some kind Thanks very much in advance.

I have made a motor but it just does not work. I wrapped 0,25 mm sq copper wire 300 times around a magnet. And i connect the beginning and the end of the wire with some copper so that electricity can go through ( i do not know if it is right or wrong ). I tried to put on some batteries, i even tried to connect the wire to the electric socket but it does not work, either. What have i done wrong ? thanks a lots

Hello we bought a cutter from Europe. It came with 400V 0.75W 3 phase motor. The motor has leads W2, U2, V2 U1,V1, W1 To convert to the 240 V single phase we jumped (W2,U1), (U2, V1), (V2,W1). We also put 50uf capacitor between (W2,U1), and (V2,W1) .See attached pictures. However the motor starts and spins for about 5mins then it trips the breaker. The motor heats up . Voltage reading Between (W2,U1) and (U2, V1) =240v Between (W2,U1) and (V2,W1) = 370v Between (U2, V1) and (V2,W1) =240v We thought (W2,U1) and (V2,W1) = 370v was little high. Also the resistance between winding W1W2 is 36 ohms, U1U2 20 ohms, V1V2 20ohms Can someone help? I will really appreciate you help

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

My local Habitat for Humanity ReStore has a bunch of used Baldor Brand AC motors for $40. Power ranges from 1HP to 7.5 HP. It seems like a good deal since these things retail for a couple of hundred. I was wondering what I could use one of these for. Also, could I just wire one of these things up to a wall outlet to make it run, or would I need some kind of controller. What considerations should I take in picking which motor to buy? power? 3 phase vs 1 phase? etc?

Hi Everybody, I've been away for a while, partly because my pc would not let me post to Instructables, and partly through illness. I will get to my projects very shortly and complete them. I need to buy an electric motor for a friends current project, but I don't know how to choose one wisely. Essentially it is a Ferris Wheel for Teddies, yes, really! We indulge our kids! We have worked out the frame weighs about 6 kilos and the contents will weigh about 30 kilos. The wheel will not spin at the centre, but at the edge, like a real Ferris wheel. So I think I will need a slow motor with high torque. Each revoloution should take about one hour (some of the kids are disabled and physically slow, plus if it goes slow enough they'll fall asleep through boredom! Only kidding! I really do need this slow) Additionally it would be great if the motor could be low voltage. So any tips on how I would achieve this, please?

A while back you may (or may not) have seen this Japanese electric motorcycle prototype called the EV-X7. It was advertised to use a "Super Electric Motor" that was the combination of a permanent magnet and an electromagnet (isn't that was a motor is?) which would allow the vehicle a range as much as 180 kilometers (111.846815 miles) on one charge with a top speed of about 150 kilometers per hour (93.2056788 mi / hr).A few sources said that in about a year they would start producing a smaller version... That was 2007, and the company's website doesn't look very promising...Ok, so now what? Too bad, eh? Well, yes...However, the research company, Genesis, seemed to have posted something on their website:Translated WebsiteAnyone wanna see if they can build one? =D

If you see in my picture if u put magnets at an angle so the poles would be opposite of 1 below it would it turn a wheel like this in my pic : i don't know how to put a pick in here so look at my profile pic please .
