A three-phase electrically magnetized synchronous machine has been studied. The peculiarity of the motor is that the magnetization coils are locating on the stationary part and no sources of magnetic energy are introduced in the moving part. The conventional electrical coupling via slip rings has been replaced with a magnetic coupling via additional air-gap. The idea of the design is to investigate a low speed high torque direct drive system more suitable than PM motors where field-weakening operation is required
