Magnetic circuit

In this page, we study several magnetic circuits in order to modelize the reluctance motor.

The reluctance motor

Advantages of the reluctance motor:
  • no permanent magnet
  • consists mostly of soft iron and wiring
  • simple mechanics
  • also efficient at high speed
  • only limited by the electrical power source and electrical switching speed
Disadvantages of the reluctance motor:
  • Advanced electronics
  • Requires current sensors and position sensor
