CONSEQUENT-POLE MOTOR ROTOR WITH MAGNETIC-FLUX-SEPARATING RECESSES

摘要

A consequent-pole motor rotor with magnetic-flux-separating recesses has a main body and multiple magnets. The main body has multiple magnet holes, multiple rotor air hole assemblies, and multiple magnetic-flux-separating recess assemblies. The magnet holes and the rotor air hole assemblies are formed through the main body. The magnetic-flux-separating recess assemblies are radially formed in a radial outer surface of the main body and extend through two axial end surfaces of the same. Each magnetic-flux-separating recess assembly has at least one magnetic-flux-separating recess. The magnetic lines produced during the operating of the motor can be pushed by the magnetic-flux-separating recesses toward the center of the main body, so the outermost magnetic line will be less likely to deviate from its path and probability of cogging torque in the motor during operation is reduced.
