Web19 sep. 2015 · 1. The ONLY is going to be use a VFD. To vary the speed of a three phase motor, you need to change both the frequency and voltage. That is exactly what a variable frequency drive does. Using a rheostat to vary the voltage will cause the torque to drop off, but won't change the speed until except that it will drop when loaded due to reduced torque. Web8 sep. 2024 · Applications. Rheostat is generally used in applications where high voltage or current is required such as: Changing the light intensity of a light bulb. An increase in the resistance of the rheostat decreases the flow of electric current, leading to dimming of lights and vice-versa. Generators. Motor speed.

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. WebThe temperature coefficient is a measure of how much the resistance will change as the temperature changes. TCR is measured in units of ppm/˚C. If a manufacturer rates a resistor at 50 ppm/˚C, the resistor will not change more than 50 Ω in resistance for each 1 MΩ of the resistors given value, for a temperature change of 1 ˚C.
