Two induction motor resistor speed control

WebOct 3, 2024 · If a small induction motor has a non-linear load, such as a fan, you can somewhat control the motor speed by reducing the motor voltage. In that case the motor no longer has sufficient torque to maintain its speed and starts operating at a lower speed, with a large amount of slip between the synchronous speed and the actual speed. WebThese devices control the speed of the motor by directly changing the frequency or the amplitude. By using the system to that end, there are hardly any heat losses and the speed control provides numerous programs that allow you to operate the machines. This is very important when you start and break in large electric motors, because the ...
