Re: Motor, potentiometer, & power supply.

dacflyer <p>Thanks. I don't know why I didn't think of a sewing machine. If the motors small enough it just might work. I'll start looking this weekend.

Re: Motor, potentiometer, & power supply.

I'm from Orange County California.<p>I think I'll try building a series of cicuits starting off simple and like stairs work my way up. This weekend I'll go to Radio Shack and try getting a cheap motor, battery, wire, switch and hook them up like you suggest. Next the rheostat or LM317. When my back ...

Re: Motor, potentiometer, & power supply.

I'm using it to control the speed of a fan. It's mostly a learning project. Someday I want to design my home with a series of fans to constantly move warm air and carbon dioxide from room to room and out of the house. I may have other ideas regarding fans to. <p>I think I will order that back issue ...

Re: Motor, potentiometer, & power supply.

This is a little more complicated than I originally thought. But I’m learning.<p>It sounds like I should just order a 12 vdc permanent magnet motor of at least 3000rpm and work from there. I will look for the (PN 0123850R) from Windsor Distributors Company you mentioned and see what else they have.<...

Re: Motor, potentiometer, & power supply.

I will attach fan blades.
Is a simple rheostat power control two devices in one?
1. converts ac to dc.
2. used to adjust the speed of the fan, kind of like adjusting the speed of the slot cars.

Re: Motor, potentiometer, & power supply.

Can an electric screwdriver produce at least 3000rpm? I also need to mount the motor on a metal plate, tighten it down and attach something to the drive shaft.<p>By the way thanks for the "servo motor controller" tip. That may come in handy in the future when I'm more knowledgeable.

Re: Motor, potentiometer, & power supply.

I can be flexable with tork if it will make selecting the right kind of motor easier.

Re: Motor, potentiometer, & power supply.

Hi.<p>1. I would like to use a small motor preferably no larger than 3 cubic inches. Maybe a computer hard drive motor would work. 2. I want to very the speed with a knob or some control from about 120rpm to at least 3000rpm. 3. I would rather this motor not slow down when there is a load put on it....

Motor, potentiometer, & power supply.

Hi I'm new to electronics.<p>I want to mount a small motor on metal, turn it on and very the speed of the motor with a control knob. I know I can buy parts at Digi-key but I don't know just what to buy. For example: 1. How does the motor plug into the wall? 2. Must I wire this through a potentiomete...
