A switched reluctance machine (=variable reluctance machine in the United States) is a motor or a generator with the following charateristics:

  • Like other types of reluctance machines, its "torque is produced by the tendency of its movable part to move to a position where the inductance of the excited winding is maximised" (Miller: Electric Control of Switched Reluctance Machines (2001)).
  • The stator and the rotor both have salient poles (contrary to synchronous reluctance motors with smooth stators)
  • The stator has concentrated windings, wound on the stator poles
  • Torque is generated by letting a sequence of current pulses flow through the stator coils
  • The flux-linkage through each stator coil has a triangular or sawtooth waveform (not sinusoidal like synchronous reluctance motors )

Switched reluctance machines and variable reluctance stepper motors are very similar, but differ in control method and application: Usually, stepper motors are open-loop controlled (no rotor position feedback), built to be precise but not to be very energy efficient. On the contrary, switched reluctance machines usually use rotor position feedback and are designed to be energy efficient.
