| Abstract: | Formulas of electromotiveforce and electromagnetic torque of rare earth permanent magnet brushless DC motor are developed by using the method of analysing DC motor. The armature reaction of the motor is discussed. The result that the flux per pole is approximately equal in no load and load is retained. |
