MV1027 Synchronous Machine

Description

The machine has a DC excited rotor with salient poles, operating on voltages up to 220 V DC (maximum excitation)

The advantages rising from this type of machine are measurements and characteristics corresponding to those of larger machines and the excitation voltage is readily available in most laboratories. An additional damping winding will counteract oscillations and also facilitate return to synchronism if the rotor falls out of phase.

The damping winding also allows the motor to be started as an asynchronous motor before energizing the field.

Suitable excitation rheostat : MV1905.
