Problems solved by technology

[0002] The current three-phase permanent magnet synchronous motor design does not take into account the motor shielding problem. The electromagnetic waves generated by the motor may come out through the gaps such as the end cover and outlet of the motor, causing electromagnetic interference. The overall motor does not play a shielding role. Make other systems subject to electromagnetic wave interference

Abstract

The invention discloses a three-phase-shielded permanent magnet synchronous motor which comprises a back end cap, a stator, a permanent magnet rotor, a front end cap, a protective cover, a terminal block, an encoder and a conductive sealing material. According to the three-phase-shielded permanent magnet synchronous motor, electromagnetic waves which are generated by the motor can be totally shielded in the motor so that leakage of the electromagnetic wave to outside of the motor is prevented, thereby preventing electromagnetic interference to other systems.

Description

technical field [0001] The invention relates to a motor, in particular to a three-phase shielded permanent magnet synchronous motor. Background technique [0002] The current three-phase permanent magnet synchronous motor design does not take into account the motor shielding problem. The electromagnetic waves generated by the motor may come out through the gaps such as the end cover and outlet of the motor, causing electromagnetic interference. The overall motor does not play a shielding role. Make other systems subject to electromagnetic interference. Contents of the invention [0003] The technical problem solved by the present invention is to provide a three-phase shielded permanent magnet synchronous motor, which can shield all the electromagnetic waves generated by the motor inside the motor, so that the electromagnetic waves will not leak to the outside of the motor and will not cause electromagnetic interference to other systems. [0004] The technical solution is ...
