Embodiment 1

[0031] combined with Figure 1-6 , the rotor core of this embodiment includes a plurality of stacked first chips 1 and second chips 2, the first chips 1 and the second chips 2 are alternately arranged, and the first chips 1 have a plurality of First guide grooves 11 distributed in the circumferential direction, the second chip 2 has a plurality of second guide grooves 21 distributed along its circumference, the outer wall of the second chip 2 has an opening 22 extending to the second guide grooves 21 . The setting of the opening 22 enables the gas inside the rotor core, as well as impurities such as aluminum slag and oxide slag to be discharged in time, so that the performance of the rotor core is stable, not easily deformed, and the performance of the motor is improved.

Embodiment 2

[0033] combined with Figure 1-6 , Compared with the technical solution of Embodiment 1, the rotor core of this embodiment can be improved as follows: the number of the first chips 1 is greater than the number of the second chips 2 . The number of the first chips 1 is greater than the number of the second chips 2 to ensure the electromagnetic performance of the motor.

Embodiment 3

[0035] combined with Figure 1-6 , Compared with the technical solution of Embodiment 1 or 2, the rotor core of this embodiment can be improved as follows: the materials of the first chip 1 and the second chip 2 are silicon steel sheets.

Abstract

The invention discloses a motor and a rotor core thereof, and relates to the technical field of motor manufacturing. The motor comprises a plurality of first chips and second chips which are superposed; the first chips and the second chips are arranged in a staggered manner; each first chip is provided with a plurality of first guide grooves distributed along the circumferential direction of the first chip, and each second chip is provided with a plurality of second guide grooves distributed along the circumferential direction of the second chip; the outer walls of the second chips have openings extending to the second guide grooves. With the openings adopted, gas, aluminum slag, oxidizing slag and other impurities in the rotor core can be discharged in time, so that the rotor core is stable in performance and not easy to deform, and the performance of the motor is improved.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a motor and a rotor core thereof. Background technique [0002] Most of the rotor cores used in motors are closed slots, but during the die-casting process, the closed slot rotor cores will cause the air resistance generated during the injection of aluminum hydraulic pressure to be unable to discharge, and the stamping oil will be atomized at high temperature to produce oily aluminum slag and aluminum oxidation. The slag cannot be discharged, and it is easy to cause cast aluminum defects such as thin strips and shrinkage holes in the end ring. Contents of the invention [0003] 1. The technical problem to be solved by the invention [0004] Aiming at the technical problem that the closed slot rotor core will cause air resistance, oily aluminum slag and oxidized slag to be unable to be discharged during aluminum hydraulic injection, the invention provides a motor an...
