Abstract

The invention relates to an electromagnetic brake with a permanent magnet, comprising spring plates, a friction plate, a coil baffle, a stand, a coil lining, a coil, a magnetic steel framework, magnetic steel and an engine seat, wherein each spring plate is provided with a fixed hole; a plurality of spring plates are mounted at corresponding positions in the friction plates by hat pegs; the stand is sleeved on the engine seat; the coil is arranged between the engine seat and the stand; the coil lining is arranged on the inner wall of the coil; the coil baffle is arranged on the front end face of the coil; the magnetic steel framework is arranged between the inner end part of the stand and the engine seat; multiple pieces of magnetic steel are arranged in the magnetic steel framework; and a magnetic leakage channel is formed between the end parts of two adjacent pieces of magnetic steel and is bent or curved. The invention has the advantages of simple and compact structure, simple assembly process of products and favorable stability; the brake torque can be greatly increased by the improvement on the permanent magnetic steel; and the elastic service life can be prolonged by the reasonable design of a spring plate.

Description

technical field [0001] The invention relates to a brake device used in an automatic control system of a servo motor, in particular an electromagnetic brake with a permanent magnet suitable for the matching use of a servo motor, and belongs to the technical field of automation devices. Background technique [0002] At present, in conventional electromagnetic brakes with permanent magnets, the permanent magnetic steel structure is prone to magnetic flux leakage and large magnetic resistance, resulting in reduced torque. And its spring leaf adopts four pieces of independent packaging, so there will be disadvantages such as bad installation and shortened service life. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the prior art, and provide an electromagnetic brake with permanent magnets with less flux leakage, less magnetic resistance, convenient installation and greatly increased service life. [0004] According t...
