Current slide {CURRENT_SLIDE} of {TOTAL_SLIDES}- Best-selling in Speed Controls
It is inexpensive, but I'm trying to use it to control a DC treadmill motor using a rectifier. It works fine unless I make rapid speed changes, then it blows it's 2 amp fuse. Maybe I'm expecting too much from it for my application.

This is a good circuit. It uses a triac rated for 600v and 40A. The circuit starts reliably at the lowest setting, a problem with other circuit designs, and it has a replaceable fuse. I used it at 120vac and found that the entire speed control range occurred only in the last quarter turn of the potentiometer. Shunting the pot with a ~200K, 1/2W resistor would allow full control over the entire range of the pot. ! used a 180K resistor for my application since I wanted the motor to turn slowly at the lowest setting.

This motor controller is just what I needed so I can get my project to work I am making a belt grinder with a dc treadmill motor now I have variable speed awesome

it does work as expected but i did blow the fuse it would be better if you could change the fuse without taking the cover off

only drops voltage 1 volt..Not enough to control anything as far as a speed controller for small motors .There is more fluctuation in normal line voltage. Don't waste your money.
