The present disclosure relates to a rotor of a motor, a method for maintaining the rotor of the motor, the motor and a wind-power electric generator set. The rotor of the motor includes a magnetic yoke, in which the magnetic yoke is in a cylindrical-like shape, and the magnetic yoke is configured to fix a magnet on its circumference surface; and a rotor support, including a shaft connection unit and a supporting ring, in which the shaft connection unit is coaxially connectable to a rotation shaft of a motor, the supporting ring is arranged on an outer periphery of the shaft connection unit, and the magnetic yoke is connected to the supporting ring; herein, at least one of the magnetic yoke and the supporting ring of the rotor support has a structure divided into a plurality of segments in a circumference direction of itself.

Rotor of motor, method for maintaining rotor of motor, motor and wind-power electric generator set

Disclosed is a device with a stator and a rotor, the device comprising: a stator; a rotor, wherein an air gap is provided between the rotor and the stator; and an air gap protection device fixedly connected to the stator, wherein the radial distance between the air gap protection device and the rotor is less than the radial distance between the stator and the rotor, and the air gap protection device rotates relative to the rotor when in contact with the rotor. By arranging the air gap protection device fixedly connected to the stator, the air gap protection device can rotate relative to the rotor when in contact with the rotor, and the radial distance between the air gap protection device and the rotor is less than the radial distance between the stator and the rotor.
