- Abstract
- This paper proposes a novel strategy of
spoken-type IPM motor with four surface-mounted magnets
to improve torque density and decrease torque ripple, in which
the motor is with ferrite magnet. The asymmetrical rotor
structure concept is used during the design process to make
the two torque compositions of the spoken-type motor - the
reluctance torque and the magnetic torque – get a better
utilized. Under this design, the torque is improved by making
the maximum values points of the magnetic torque and the
reluctance torque be close to each other. To verify the
analysis result, the frozen permeability method (FPM) is
employed to provide feasible insights into the separation of the
torque components based on a 2-D finite element method
(FEM). To highlight the superiority of the proposed model, a
conventional spoken-type IPM motor with symmetrical rotor
structure is adopted for comparison under the same magnet
amounts, machine size and operating conditions.
