Abstract: 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.

Abstract: A rotor for a brushless motor has a main body and multiple magnet assemblies. The main body has multiple first holes that extend in a bending shape. The first holes are arranged annularly and a bent corner portion of each first hole is closer to the rotation axis of the main body. Each magnet assembly has two magnets formed as a rectangular block and is mounted in one of the first holes. An angle is between the magnets and an air interval is formed between the magnets. With such a structure, a conventional curved magnet is substituted and magnetic lines of force are more concentrated, so a stator tooth can provide higher magnetic flux density. Especially, with the air interval, the magnetic flux leakage may be decreased. Consequently, even though the total weight of magnets is reduced, the efficiency of motor is still improved.
