Problems solved by technology

[0002] In elevators with machine rooms, small machine rooms or machine rooms, motors are required. The brake drums of drum brakes are generally used in the prior art, which increases the thickness in the axial direction and wastes axial space. The structure of the pulley is too simple, and its practical function is not strong. Based on this, it is still necessary to design an outer rotor planar motor traction machine

Embodiment Construction

[0013] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0014] refer to figure 1 , the specific embodiment adopts the following technical solutions: the outer rotor planar motor traction machine includes a motor stator 1, a traction wheel 2, a permanent magnet 3, an encoder 4 and a disc brake 5, and the outer surface of the traction wheel 2 is arranged There is a wire rope groove 6, and a permanent magnet 3 is pasted on the inner surface of the traction sheave 2. As the rotor of the permanent magnet synchronous motor, one part is used as both the traction sheave and the rotor of the motor, and is also used as a brake disc. , Motor stator 1 is installed inside the motor housing, and a symmetrical three-phase AC coil is wound on the motor stator 1. An encoder 4 is installed in the middle of the hollow sh...

Abstract

The invention discloses an outer rotor plane motor traction machine and relates to the technical field of motors. The outer rotor plane motor traction machine comprises a motor stator, a traction sheave, a permanent magnet, an encoder and a disc brake, steel wire rope grooves are formed in the outer surface of the traction sheave, the permanent magnet is attached to the inner side surface of the traction sheave, the motor stator is installed inside a motor shell, symmetric three-phase alternating current coils are wound on the motor stator, the encoder is installed in the middle of a hollow shaft of a motor, a vertical plate is installed at one side of the motor shell, and the disc brake is fixed on the vertical plate. According to the outer rotor plane motor traction machine, the structural design is reasonable, the axial direction space is saved, the axial direction thickness is reduced, the practicability is great, the application range is wide, and the stable operation of an elevator lift car is guaranteed.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an outer rotor planar motor traction machine. Background technique [0002] In elevators with machine rooms, small machine rooms or machine rooms, motors are required. The brake drums of drum brakes are generally used in the prior art, which increases the thickness in the axial direction and wastes axial space. The structure of the pulley is too simple, and its practical function is not strong. Based on this, it is still necessary to design an outer rotor planar motor traction machine. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an outer rotor planar motor traction machine, which has a reasonable structural design, saves axial space, reduces axial thickness, has strong practicability, is widely used, and ensures The stable operation of the elevator car. [0004] In order to achieve the abo...
