Device for reducing running down of motor

Abstract

The invention provides a device for reducing the running down of a motor. The device comprises a motor mechanism and a brake mechanism. The motor mechanism comprises a stator, a rotor and an outer shell of the motor, wherein the stator is fixed to the inner wall of the outer shell of the motor and connected with the rotor in a rotating mode. The brake mechanism comprises a spring, a guide pillar and a brake pad, wherein one end face of the brake pad is fixedly connected with the rotor, and the other end face of the brake pad is closely attached to an armature; a guide groove is formed in the end face, which is not attached to the end face of the brake pad, of the armature; one end of the guide pillar penetrates into the guide groove, wherein the guide groove slides relative to the guide pillar; one end of the spring is connected with the end face, which is not attached to the end face of the brake pad, of the armature; the other end of the spring is fixed inside the outer shell of the motor, and the movement direction of the spring is the same as that of the guide groove. The brake mechanism further comprises an electromagnet, wherein the electromagnet is coaxial with the guide pillar. The device for reducing the running down of the motor can achieve the purposes that the brake is applied at the time of an outage, the brake is not applied during energization, the brake is applied in a mechanical mode, and the device is synchronous with the motor in operation to better reduce the running down.

Description

technical field [0001] The invention relates to the field of industrial machinery, in particular to a device for reducing motor idling. Background technique [0002] Motor devices are widely used in the field of industrial machinery. However, a serious problem that plagues people in the field is that when the motor device stops working, the rotor of the motor cannot stop moving in time. In order to solve this problem, people in the field have proposed many solutions, but these solutions are either complicated in structure, or the cost is too high or the braking force is not enough. Contents of the invention [0003] The problem to be solved by the present invention is to realize power-off braking of the electric device, and the operation of the braking device and the motor is synchronized, and the motor can be self-locked when the motor is not working. [0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a de...
