With reference to the phasor diagram, state what is meant by the load the angle of a synchronous motor. (b) What is the value of this angle when the motor runs on no-load?
(a) With reference to the phasor diagram, state what is meant by the load the angle of a synchronous motor. (b) What is the value of this angle when the motor runs on no-load? Sketch the curve of the power factor characteristic of the asynchronous motor as the excitation current changes. (b) (i) With reference … Read more
