Abstract

The present invention relates to a rotating shaft for a motor. The rotating shaft comprises a portion disposed at an output end of the rotating shaft and used for installation of a load, a portion used for installation of a rotor core of the motor, a portion used for installation of a first bearing close to the output end, and a portion used for installation of a second bearing close to a rear end opposite to the output end, and is characterized in that a circumferential groove is arranged near the portion used for installation of the first bearing on the rotating shaft. The present invention also relates to a motor including the rotating shaft. According to the rotating shaft and the motor, vibrations and noises of the motor can be reduced in a simple manner.

Description

technical field [0001] The present invention relates to electric motors, in particular to shafts for electric motors and electric motors comprising such shafts. Background technique [0002] As is well known, an electric motor generally includes a stator fixedly supported on a housing and a rotor rotatably supported on the housing through bearings and capable of rotating in a space defined by the stator. Depending on the type of motor, for example, the stator of a permanent magnet motor includes permanent magnets fixed to the housing, while the stator of an field motor includes a stator core and stator windings wound around the stator core. A rotor of an electric motor generally includes a rotating shaft, a rotor core disposed on the rotating shaft, and a rotor winding wound on the rotor core. Of course, the rotor of a switched reluctance motor has no rotor windings. When the winding of the motor is energized, a magnetic field is generated, and the rotor rotates under the ...
