Synchronous Motor DefinitionA synchronous motor is defined as a machine whose rotor speed is synchronized with the frequency of the current supply; it requires external methods for starting.f = supply frequency and p = number of poles.Self-Starting ChallengeDue to alternating magnetic forces that fail to move the rotor from a standstill, synchronous motors are not self-starting.Starting Methods of Synchronous MotorStarting a Synchronous Motor Using an Induction MotorBefore starting the synchrono
