Help Motor Control!

Hey guys, I need to create a motor that can have a fader/dial so that I can control its speed (rotations). I figure it must be a simple enough system but I don't even know where to begin in terms of parts. I just need it to be strong enough that I can spin a GoPro camera (fairly light - but not toy car motor weak). Sincerely, Alex

How to control the speed of this motor ? Answered

I have this spare Dayton Shaded Pole Motor that I would like to use for a project.  When the motor was removed, just two wires are attached to it to which I attached an adapter plug.  When plugged in to a wall outlet, it obviously runs at only one speed.  I was wondering how I could control the speed of the motor thus enabling me to lower the speed.  Would it be possible to add a dial to lower the speed?   I saw a video on youtube titled How to make a Simple Speed Controller (link: https://www.youtube.com/watch?v=0YZJ0kJEmh0) and was wonder if this would work for my motor? In the video, the guy uses a Switch, project box, and potentiometer.  However, should a rheostat be used instead? (someone posted that in the comments to the video) So, let me know what you think, and how I should go about doing this. Here are the specs of the motor: 1/40 HP 1550 rpm 115V 60 Hz 1.1 Amp Class A Ins, 40 degree C Max. Amb. Cont. Duty Thank you.

Using a hall effect sensor with TL494 pulse width modulator.

I have an electric billy cart with a dead controller board. I constructed the kit circuit below to replace the dead board and it works well enough for the job except for one small problem. The throttle on the billy cart utilizes a hall effect device and not a pot. The billy cart also has a handbrake with a switch that closes when applied. I use this with a resistor to discharge C2 and pull pin 4 (inhibit) high. This ensures a gentle start (as the capacitor slowly charges through the 100k resistor) if the brake is released with the throttle advanced. The output range of the throttle is 950 mV to 4.1 V if VREF (5V) is used as the supply. (I'm dropping it in in place of the pot.) 4.1 V is sufficient to achieve the maximum 90% duty cycle of the chip, but 950 mV leaves me with a minimum duty cycle of about 21%, and of course a motor that won't stop. Will changing the divider ratios 20k/2k2 & 47k/47k be sufficient to get me zero speed or am I going to have to do something more exotic? Thanks in advance.

115VAC low current fan speed controller

Greetings, I am fairly new to electronics, and have mostly worked with DC circuits so far.  I have an AC fan I want to use to make a carbon filtered ventilation fan for my soldering station.  I can do this with a DC circuit and DC fan, but when researching how to do it with an AC fan I came up with more questions than I started with... The fan I have is a Nidec TA450AC model A30122-10.  It is about 5x5x1.5 inches, and rated for 115VAC, 50/60Hz, .26/.21A.  I found data on the fan here: http://http://www.nidecpg.com/fanpdfs/ta450ac.pdf In my research so far it seems there might be three solutions: 1> Use a TRIAC/DIAC circuit, 2> Use a MOSFET circuit or 3> Use a microcontroller/PWM circuit.  There seem to be benefits/drawbacks to each method, and I don't know which method to choose, or even if I'm headed in the right direction..  I don't know how to tell if the fan is  single-phase, triple-phase, induction...  ugh.  I am looking for an inexpensive solution I can build myself,  that performs well. Can anyone help me find the right solution for my application?  Or at least point me in the right direction? Thanks much, doval

In the early stages of planning an electric kayak build.

After some research it appears i want a PWM Speed controller that can handle at least 24V.   Amps wise i think i want at least 4 Amps. (Assuming my calculation was correct based off the Watts and Volts )  So this is basically more of a "am i barking up the right tree" question!   As i said earlier this is just early planning stages of the build and i want to make sure i don't make any silly mistakes!  Any help is greatly appreciated!

My intention is to make the user select AUTO mode or MANUAL Mode. After selecting, the user will be asked to select speed and duration. So this requires a lot of loop-inside-a-loop, if-inside-if etc. When I'm using push button, the microcontroller cannot read the command when the second button is push. I heard, if using push button I need electronic relay.

Help with dc motor and potentiometer! Thanks

OK so my dad has this old turntable and I got him some cool records for Christmas and I tested them out and it sounded good but now the motor isn't working, its kinda temperamental. I know the motor works because i tested it separately with a 9V, i guess the wiring is just kinda old and faulty. Any way my idea is to put the motor on its own independent circuit and adjust its speed with a potentiometer. Its one of those small DC motors 12V. I was thinking about hooking it up to a battery pack and a pot to adjust the rpm, I could mount the knob on the face of the player and adjust it until the music sounds just right. Then i could make a mark for 33 rpm and 45 rpm so he can change records with just a twist of the knob. Or slow them down and speed them up just for fun lol. How can I wire all this? I did some googling and tried with a couple pots and motors I've harvested over the years but all the pots seem to smoke and sizzle with only a 9V battery. Do I need a different pot?
