Why permanent magnet technology

Why permanent magnet technology

Conventional synchronous machines

  • Magnetic field is created by feeding current into the rotor winding
  • Massive field poles in the rotor bring complexity and losses in the system

 

Permanent magnet machines

  • Magnetic field is created in a simple way without losses by using magnets instead of a rotor winding
