Universal Motor: Construction, Working, Principles

WebEven when used with AC power source, this motor can rotate at a rotation speed above the frequency of the supply, and because most electric motor properties improve with speed, however, universal motors are inefficient: up to 70–75% for larger motors and around 30% for smaller motors. WebIdeally, motor speed should be proportional to voltage, so it should remain constant regardless of torque. In reality however, increasing torque increases the current, which in turn results in more resistive losses in the motor. As a result, less voltage remains available to counter back-EMF, and the motor speed drops.
