Problems solved by technology
[0002] The brake motor is a common power source component in daily production and life. It converts electrical energy into rotational potential energy and outputs it to the outside, and the output shaft is connected to the load device, thereby providing power to the load device, and the output shaft of the brake motor can quickly stop and brake. Motors are widely used in machine tool processing. The purpose is to improve the processing efficiency of machine tools on the one hand, and improve the safety performance of machine tools on the other hand. At present, the structure and principle of brake motors are complex, costly, and difficult to repair and maintain. Therefore, it is necessary for the present invention to provide an electromagnetically triggered emergency braking method for an electric motor with ingenious structure, simple principle, high safety and convenient operation.

The invention provides an electromagnetic braking method of a brake motor, which comprises the following steps: firstly, a controller controls a circuit to enable a motor body to normally start and operate, and a rotating spindle is connected with load equipment and outputs rotating potential energy outwards from a power output end of the rotating spindle; secondly, when the rotating spindle needsto be stopped suddenly under an emergency, the controller controls the circuit to stop supplying power to the motor body and controls the circuit to start an electromagnetic triggering mechanism, theelectromagnetic triggering mechanism converts electric energy into a magnetic field and forms magnetic attraction to a limiting mechanism to enable the limiting mechanism to relieve the limiting constraint on a friction mechanism, the friction mechanism is automatically switched from a non-braking state to a braking state and applies a braking force to the rotating spindle, and the rotating spindle rapidly stops rotating under the action of the braking power applied by the friction mechanism; and finally, the electromagnetic triggering mechanism is powered off and resets, the friction mechanism is switched from the braking state to the non-braking state, and the limiting mechanism recovers the limiting constraint on the friction mechanism.
