Title: Adjustable flux permanent magnet brushless AC or DC motor
Inventor: CHAN CHING CHUEN
IPC: H02K1/27
Filed: 1993-11-17
Abstract: The stator of the motor is similar to that of conventional ac motor, whereas the rotor incorporates magnetic bridge b between circumferentially adjacent pole pieces p. Auxiliary air gaps g may be provided in the bridge b. The magnetic bridges b provide parallel paths for air gap flux so that the airgap flux can be adjusted effectively, efficiently and flexibly. The distinct features of the design lie in: (i) the airgap flux consists of two parallel flux, (ii) the magnetic paths are optimized, (iii) the reluctance of direct axis armature flux is significantly smaller than that of conventional permanent magnet ac motor, (iv) the arrangement of the permanent magnet m is so designed that no magnetic isolation is required at the rotor shaft, and (v) the configuration of the permanent magnets and the construction of the rotor are simple. Therefore, the motor possesses the following major advantages: (i) higher power-to-weight ratio, (ii) higher performance-to-cost ratio and (iii) higher efficiencies over the operating torque-speed range. The motor is suitable for use in an electric vehicle. <IMAGE>
