Abstract

The invention relates to a permanent-magnet synchronous traction machine. The permanent-magnet synchronous traction machine comprises a base, a stator, a rotor block, a band-type brake, a traction sheave, a permanent magnet, oil nozzles, a self-aligning roller bearing, a rotary shaft, elastic cylindrical pins, a double-side sealed deep groove ball bearing, an inner bearing cover, a support, an encoder, brake arms, brake shoes and friction plates which are manufactured to form the permanent-magnet synchronous traction machine. The permanent-magnet synchronous traction machine has the advantages that noise generated during brake is low, a brake system is table, and the integral performance of equipment is improved.

Description

technical field [0001] The invention relates to the field of elevator equipment, in particular to a permanent magnet synchronous traction machine. Background technique [0002] With the development of modern control theory and technology and the progress of permanent magnet motor design and manufacturing technology, elevator traction drive technology has also been developed rapidly. The gearless traction machine directly driven by permanent magnet synchronous motor has been widely used. Compared with the asynchronous traction machine, the permanent magnet synchronous traction machine cancels the gear reduction box, realizes the gearless direct drive of the elevator, greatly improves the transmission efficiency of the system, reduces the overall volume of the system, and makes the transmission system stable in vibration, noise and The running performance such as low-speed stability has been improved. [0003] At present, the gearless tractors on the market have basically rep...
