WebAs your current speed is 1750rpm, however, I assume that your motor is asynchronous. Therefore, you can decrease your effective speed by using a rheostat, as long as your slip is low enough to keep your motor running. Obviously, you'll still decrease your system efficiency. In my opinion, you should go for VFD: for a 1.12kW motor, this is cheap. WebThese circuits cause highly distorted currents leading to a low power factor. Knowing this, you will easily find examples of such circuits online. Varying current through an incandescent lamp with a series resistor (rheostat, potentiometer) wastes an unacceptable, even unmanageable, amount of power. Note that this applies to incandescent lamps.
