Embodiment Construction

[0030] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0031] Please refer to figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 . An elevator ring-type outer rotor permanent magnet brake according to an embodiment of the present invention, such as figure 1 As shown, it includes a first permanent magnet 1 , a second permanent magnet 2 , an electromagnet 3 , a rotor 4 and a fixing frame 5 .

[0032] The rotor 4 is sheathed on the shaft of the traction machine (not shown), and the rotor 4 and the shaft of the traction machine can be fixedly connected through a shaft coupling to realize synchronous rotation. The rotor 4 extends radially inwards relative to the traction machine shaft.

[0033] The rotor 4 can directly serve as the second permanent magnet 2, that is, the rotor 4 itself can be integrally made of p...

Abstract

The invention provides an elevator ring type outer rotor outer rotor permanent magnet brake. The elevator ring type outer rotor outer rotor permanent magnet brake comprises a first permanent magnet, asecond permanent magnet and an electromagnet, wherein the second permanent magnet surrounds the periphery of the first permanent magnet; the second permanent magnet is fixedly connected with a traction machine shaft and rotates along with the traction machine shaft; the first permanent magnet provides a first magnetic field, the second permanent magnet provides a second magnetic field, and the first magnetic field attracts the second magnetic field to provide braking force for stopping the second permanent magnet from rotating; the electromagnet is arranged between the first permanent magnetand the second permanent magnet, and the electromagnet selectively provides a third magnetic field; the third magnetic field controls the influence of the first magnetic field on the second magnetic field so as to control the braking force; and the elevator ring type outer rotor permanent magnet brake is braked by magnetic force, so that various mechanical faults existing in mechanical braking canbe effectively avoided.

Description

technical field [0001] The invention relates to the field of elevator braking, in particular to an elevator ring-type outer rotor permanent magnet brake. Background technique [0002] The elevator brake is a key component to ensure the normal and safe operation of the elevator. When the elevator car stops running, the brake brakes the brake to keep the elevator car at the level or the desired position. [0003] Traditional elevator brakes include drum brakes, block brakes and butterfly brakes. Their working principles are basically the same, that is, when the electromagnet is energized, the brake shoe and the brake wheel are disengaged by the electromagnetic force to overcome the elastic force of the spring (brake release). ), when the electromagnet is de-energized, the brake shoe is attached to the brake wheel under the action of the spring to achieve braking (holding brake). [0004] Since the above-mentioned traditional elevator brakes rely on springs to push the brake s...
