Title: homemade cresting machine - electrical question
Post by: TroyH on September 16, 2009, 02:17:00 PM
Made myself a homemade cresting machine.  Getting ready to try it out, but am concerned that it spins too fast.  Was reading that it should spin around 300 rpm.  Mine is from a small fan motor and is probably much faster.
I bought a standard dimmer switch, but when I hook it up, the motor barely turns when the switch is turned all the way on.
The dimmer is a standard 120v, reads 600w.
I don't know much when it comes to electricity, just some basics, so is there a different dimmer switch I should get, or is the problem with the motor I'm using?

This may sound stupid but is it a AC or DC motor?

Not sure about what you have,but old sewing machine motors work real well,with the foot pedal to control speed.

Pastorhunter,
I don't know exactly the motor you have but you will need a speed contol for a fan not a light dimmer switch.There is a dimmer called a triac based dimmer that you can get from a radio shack that would work but a speed control for a fan from  Home Depot or Lowes should work and is i think around $15.00.If you run into and problems send me a PM with you're phone number and we will work it out.

PastorHunter, There are many different style motors out there and some might turn with a light dimmer but it's the wrong device for the job.I don,t consider myself an expert but have been an electrician for many moons.If you need some help let me know.
