What are the main characteristics of synchronous motor?
What are the main characteristics of synchronous motor? Main Features of Synchronous Motors Synchronous motors are inherently not self starting. The speed of operation of is in synchronism with the supply frequency and hence for constant supply frequency they behave as constant speed motor irrespective of load condition. Why synchronous motor is a constant speed […]
