Synchronous Machines Questions And Answers
Synchronous Machines Questions And Answers. Electrical machines questions on “efficiency of synchronous machines”. Dear readers, welcome to synchronous motor interview questions and answers have.
Electrical machines multiple choice questions on “synchronous machine applications”. The speed at which the stator field rotates is called synchronous speed and it depends upon the frequency of supply and number of poles for which the stator is wound. A synchronous motor always runs at synchronous speed because of the magnetic locking.
