Question

A trapezoidal permanent magnet ac motor is fed by a quasi rectangular current of 120o pulse width, such that the current pulse is located in the region where the induced voltage is constant and maximum. The torque produced by the motor is proportional to

Answer 1

Answer:

Explanation:

A trapezoidal permanent magnet ac motor is fed by a quasi rectangular current of 120o pulse width, such that the current pulse is located in the region where the induced voltage is constant and maximum. The torque produced by the motor is proportional to

the current flows in the DC power links.
