WIPO Patent Application WO/2024/042986
Kind Code:
A1
Abstract:
[Problem] To provide an electric compressor that can cut down a material cost with a reduction in the dimension of an end plate used to prevent movement of a permanent magnet embedded in a rotor core of a motor. [Solution] This electric compressor is provided with a motor 2 having a rotor 23 in which a permanent magnet is embedded in a rotor core 62. End plates 71 and 72 provided at ends in an axial direction of the rotor core 62 and used to restrict movement in the axial direction of a permanent magnet 68 and balance weights 73 and 74 provided at the ends in the axial direction of the rotor core 62 are provided. The end plates 71 and 72 cover a part of an end surface in the axial direction of the rotor core 62, and the balance weights 73 and 74 cover the remaining part of the end surface to restrict movement in the axial direction of the permanent magnet 68.
