Tractor for elevator
The present invention discloses a tractor for an elevator. The tractor comprises a motor, a fixed machine base, a fixed main shaft, a rotor case, a rope wheel for driving ropes of the elevator, a bearing, a rotating body and an encoder, wherein a stator installation part is disposed at a hollow disc-type extension part of the fixed machine base, a rotor installation part is disposed at a hollow disc-type extension part of the rotor case and is opposed to the stator installation part, the diameter of a hollow part of the fixed main shaft is larger than that of a rotating shaft part of the rotating body, the rotating body rotates along with the rotor case, and the encoder is disposed at the rotating shaft part of the rotating body. A novel structure is provided for the elevator tractor using a disc-type electric motor, the tractor is fully utilized to fix space of the hollow part of a main shaft, arrangement and operation of the encoder become convenient, overall thinness of the tractor is maintained, and the tractor is suitable for elevators, with small machine rooms or without machine rooms, requiring thinness of the tractor.
