The embodiment of the invention provides a motor rotor and a motor. The motor rotor comprises a plurality of rotor punching sheets and support ribs; each rotor punching sheet is provided with a magnetic barrier through hole with a preset shape; the plurality of rotor punching sheets are arranged in an overlapping manner; the magnetic barrier through holes in the plurality of rotor punching sheetsare arranged oppositely; the supporting ribs are arranged in the magnetic barrier through holes between the rotor punching sheets in a penetrating mode; the side edges of the supporting ribs are fixedly connected with the rotor punching sheets respectively; and the supporting ribs do not conduct magnetism. According to the motor rotor and the motor provided by the embodiment of the invention, themechanical strength of the rotor can be improved on the premise of not arranging a magnetic isolation bridge, so that the problem that the mechanical strength of the rotor is reduced due to thinning of the magnetic isolation bridge in the prior art is solved, and a relatively good effect is achieved.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of electromagnetic equipment, and in particular to a motor rotor and a motor. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction, usually including a rotor and a stator. The function of the motor is mainly to convert mechanical energy into electrical energy, so the efficiency of converting mechanical energy into electrical energy reflects the working efficiency of the motor. [0003] The types of motors mainly include permanent magnet motors and reluctance motors. In permanent magnet motors, a magnetic isolation bridge is usually installed, and the magnetic flux at the magnetic bridge reaches saturation to limit the magnetic flux leakage and improve the working efficiency of the motor. Therefore, from the perspective of preventing magnetic flux leakage, the smaller the width o...
