Switched reluctance motors convert reluctance torque into mechanical power. Power is delivered to windings in the stator rather than the rotor. When power is delivered to the stator windings, the rotor's magnetic reluctance creates a force that attempts to align the rotor with the powered windings. In order to maintain rotation, adjacent windings are powered up in turn. Modern designs feature a high-power electronic switching system that offers advantages in terms of control and power shaping.

Key Characteristics

  • Does not utilize a permanent magnet
  • Pointed poles in both stator and rotor
  • Comparatively robust and efficient
  • Suitable for use in very high ambient temperatures
  • Disadvantages: acoustic noise and torque ripple
