Document Type and Number:
WIPO Patent Application WO/2023/103138
Kind Code:
A1
Abstract:
Disclosed is a method for collaborative optimization design of permanent magnet-armature double harmonics of a magnetic field-modulated permanent magnet motor. An expression between a flux linkage and a magnetic field harmonic is established according to a harmonic characteristic formula of permanent magnet and armature magnetic fields; and the influence of the flux linkages corresponding to the permanent magnet and armature magnetic field harmonics on torque and power factor is analyzed according to a vector diagram and a power factor expression, so that a collaborative optimization design thought for permanent magnet-armature double harmonics is established. The dimensions of armature magnetic field harmonic optimization objectives and design parameters are reduced by means of sensitivity analysis, experimental point distribution calculation, and independence judgment for an armature magnetic field non-working harmonic; a parameter range constrained by the permanent magnet magnetic field harmonic is taken as a constraint condition to optimize the armature magnetic field harmonic by using a Kriging model and a multi-objective optimization algorithm, so that collaborative optimization design for the permanent magnet-armature magnetic field double harmonics is achieved, thereby improving the torque density and power factor of the motor.
