Description

A energized electromagnetic brake suitable for rotating stage

technical field

The utility model relates to an energized electromagnetic brake, in particular to an energized electromagnetic brake suitable for a rotating stage.

Background technique

The energized electromagnetic brake is a device that has the functions of decelerating, stopping or keeping the moving parts (or moving machinery) in a stopped state. It is a mechanical part that stops or slows down the moving parts in the machine. Commonly known as brakes, brakes. The energized electromagnetic brake is mainly composed of frame, brake parts and operating device. Some brakes are also equipped with an automatic adjustment device for the clearance of the brake parts. In order to reduce the braking torque and structural size, the energized electromagnetic brake is usually installed on the high-speed shaft of the equipment.

At present, the principle of the energized electromagnetic brake on the rotating stage is that when the motor is energized, the electromagnet converts the alternating current in the motor into direct current through a rectifier, generates magnetic force through the direct current electromagnet, attracts the armature, and the friction disc is separated from the rear end cover of the motor. turn. When the motor is powered off, the magnetic force disappears, and the armature presses the friction disc under the force of the brake spring, and the friction disc and the rear end cover generate a moment of friction, and the motor stops rotating. Disadvantages of the currently used brakes: the armature brake is unstable, the brake balance is poor, and the noise generated by the brake disc is large, which affects the no-load current of the motor. The strength of the existing small teeth linked by the brake disc and the motor shaft is insufficient, and the fit between the teeth is not tight enough.
