Abstract

The invention relates to the technical field of braking motors, in particular to a motor with a good braking effect, which comprises a machine body and a rotor rotationally connected in the machine body, a rotating shaft of the rotor extends out of one end of the machine body, and a braking device for braking the rotating shaft is arranged at the end part of the machine body. The braking device comprises a brake shell fixed to the machine body, a brake shoe arranged on the brake shell and used for abutting against the rotating shaft, an electromagnet arranged on the brake shell and used for attracting the brake shoe to be away from the rotating shaft, and an elastic piece arranged on the brake shell and used for driving the brake shoe to reset. One end of each brake shoe is hinged to the brake shell, the other end of each brake shoe is a free end, the number of the brake shoes is not less than three in the circumferential direction of the rotating shaft, and the free ends of the brake shoes are distributed in a spiral shape. The motor has the following effects that during braking, the influence on the brake shoe is reduced, shaking is reduced, and the braking effect is more stable.

Description

technical field [0001] The present application relates to the technical field of braking motors, in particular to a motor with good braking effect. Background technique [0002] After the ordinary motor is powered off, the rotor will continue to rotate under the action of inertia, which is suitable for working conditions such as winches. The brake motor is a motor with an electromagnetic brake function, and the electromagnetic brake is realized by an electromagnet; the electromagnetic brake motor can quickly stop when it stops, and is suitable for driving occasions that require fast braking. [0003] A general brake motor includes a body 100, a rotor 110 is rotatably connected to the body 100, a rotating shaft is provided on the rotor 110, one end of the rotating shaft extends out of the body 100, and a brake housing 121 is fixedly connected to the body 100. An electromagnet body 123 is fixed on the inner wall of the brake housing 121, and the electromagnet body 123 is in a...
