Problems solved by technology

[0003] When the brake is working, the friction plate will inevitably generate dust. When the friction plate is not flat or the material is not good, the amount of dust generated will be greater. If the generated dust is not collected and cleaned in time, it will Floating in the motor shell, it is easy to enter the precision components such as bearings, oil seals, encoders, etc., which will damage the components and cause the motor to fail to work normally

Embodiment Construction

[0030] see in conjunction Figure 1 to Figure 4 As shown, according to the embodiment of the present invention, a brake is provided for use in a motor, including a brake stator 1, an armature 2, a friction plate 3 and a dust collection device 4, and the armature 2 is located between the brake stator 1 and the Between the friction plates 3, and the armature 2 can move toward or away from the friction plates 3 to realize motor braking or release the brake, and the dust collecting device 4 can collect the dust produced by the friction plates 3 during braking. Dust, specifically, the brake stator 1 can be flexibly connected with the armature 2 through the guide post 11, for example, an electromagnetic coil is arranged in the brake stator 1, and when the electromagnetic coil is energized, a magnetic force is generated, and the generated magnetic force will attract The armature 2 is combined to force the armature 2 to move away from the friction plate 3, that is, the brake release o...

Abstract

The invention provides a brake and a motor. The brake is used in motors, and the brake includes a brake stator, an armature, a friction plate and a dust collecting device, wherein the armature is positioned between the brake stator and the friction plate, and the armature is movable toward or away from the friction plate to effect braking or unbraking of the motor, and the dust collecting device is capable of collecting dust generated by the friction plate when braking. According to the brake and the motor of the invention, the dust generated by the friction plate when the brake is running iscollected timely through the dust collecting device to prevent the generated dust from entering the precision components inside the motor, so as to ensure the operation reliability of the motor.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to a brake and a motor. Background technique [0002] The brake is one of the common parts of the servo motor, which is used to lock the rotation of the shaft when the motor is powered off. Traditional brakes generally use electromagnetic coils and springs to work together to control the friction coefficient between the friction plate and the armature and the plate by controlling the relative gap state of the friction plate in the brake; when the motor is running normally (that is, the shaft rotates) , the brake does not work, and the friction plate is in a free state in the axial direction of the brake (there is a gap between the friction plate, the armature and the plate), and the friction coefficient is approximately 0 at this time; when the motor is powered off or the position is maintained, the brake works, and the friction The plate is locked in the ax...
