Abstract

The invention relates to the technical field of rotating parts of magnetic circuits, in particular to a rotor punching plate adapting to high-speed rotation. The rotor punching plate comprises a punching plate body, wherein a magnetic steel placement cavity is arranged on the edge of the punching plate body; a magnetic bridge is arranged at the end part of the magnetic steel placement cavity; themagnetic bridge is sequentially provided with a straight section and a reinforcing section along the length direction; the side, toward the magnetic steel placement cavity, of the straight section isa straight edge; one side, toward the magnetic steel placement cavity, of the reinforcing section is arranged in a rounded manner; a boss is arranged at one side, back to the magnetic steel placementcavity, of the reinforcing section; and the width of the reinforcing section is gradually increased from one end close to the straight section to one end far away from the straight section. Accordingto the rotor punching plate, the problem that the magnetic bridge of the rotor punching plate is easily damaged under the condition of high-speed rotation in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of rotating components of a magnetic circuit, in particular to a rotor punching plate adapted to high-speed rotation. Background technique [0002] Now there are higher and higher requirements for the efficiency of new energy vehicle motors. It is hoped that the motors will have higher power density and higher efficiency. The wider the high-efficiency range, the better. In order to adapt to the characteristics of small volume, small moment of inertia, fast dynamic response and good peak speed performance of the new energy vehicle motor, higher requirements are put forward for the speed of the motor. Therefore, as the speed of the motor increases, higher requirements are placed on the strength design and reliability of the rotor punch. [0003] The edge of the rotor punching sheet of the motor is provided with a magnet steel placement cavity inside, and the magnet steel placement cavity is provided with a ma...
