Electromagnetic brake motor

Abstract

The invention discloses an electromagnetic brake motor, and relates to the technical field of motors. According to the technical scheme, the electromagnetic brake motor comprises a machine shell, a rotating shaft and an electromagnet, wherein a brake shaft is rotationally arranged in the machine shell, the brake shaft is sleeved with a clutch cylinder, the clutch cylinder can slide in the axial direction of the brake shaft but cannot continuously rotate around the brake shaft, the rotating shaft is provided with a first tooth part facing the clutch cylinder, the end, facing the first tooth part, of the clutch cylinder is provided with a second tooth part, a spring is arranged between the clutch cylinder and the brake shaft, the elastic force of a spring drives the first tooth part and thesecond tooth part to be connected in an inserted mode, the clutch cylinder is made of a ferromagnetic material, the electromagnet right faces the clutch cylinder, a friction disc is fixed to the brakeshaft, a brake disc is fixed to the machine shell, and the friction disc and the brake disc are kept in an abutting state. When the motor operates normally, the brake shaft and the friction disc do not rotate, so that an energy-saving effect is achieved; when the power supply of the motor is cut off accidentally, the motor can still realize automatic braking of the rotating shaft, so that the motor is relatively safe; and heat dissipation of the friction disc and the brake disc is efficient.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an electromagnetic braking motor. Background technique [0002] Motor refers to the power device that converts electrical energy into mechanical energy (rotation form) according to the law of electromagnetic induction, and is widely used in various mechanical equipment. After the motor is powered off, the shaft, rotor and the objects it drives will continue to rotate for a period of time due to inertia. Due to factors such as safety or processing efficiency, in many cases, the motor needs to stop rotating quickly after power off. At present, in order to realize the rapid stop of the motor, the electromagnetic brake is often used in technology to quickly stop the rotating shaft. [0003] The Chinese invention patent application with the existing application publication number CN106787424A discloses an electromagnetic brake motor, which includes a motor body, an end cover with vent...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: in order to achieve a better braking effect, the friction plate needs a certain braking contact area, so the size of the friction plate should not be too small; the rotating shaft of the motor continues to drive the friction plate Rotation, the friction plate will cause resistance to the rotation of the shaft during operation, especially when the motor starts or the speed increases, there is a waste of energy
