WebIn case of a series resistor a lot of power is dissipated in the series resistor. Speed control behavior With PWM the motor will 'see' a very low power supply impedance, even though the power supply is constantly switching between high and low voltages. The result is that the motor has a much higher torque. WebAug 30, 2024 · The disadvantages of the rotor resistance starter are given as follows −. Lower efficiency due to the I 2 R losses in the external resistance connected in the rotor circuit. This starter can only be used for starting a slip ring induction motor. It needs frequent maintenance due to presence of slip rings and carbon brushes. lyrics to song magic https://innerbeautyworkshops.com
