1. An automatic synchronous motor starter can be used with a synchronous motor to provide automatic control of the startup sequence. 2. There are three basic methods of starting synchronous motors automatically. 3. The squirrel cage winding will overheat if a synchronous motor starts, accelerates, and reaches synchronous speed within a time interval determined to be normal for the motor. 4. A synchronous motor is started by accelerating the motor to as high a speed as possible from the squirrel cage winding and then applying the DC field excitation. 5. The development of the brushless DC exciter is an improvement in synchronous motor excitation.
