Detailed Description
The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.
As shown in fig. 1-2, a motor braking device, including the motor, it includes brake disc 4, 4 covers of brake disc are established on 1 main shaft shell of motor, brake disc 4 passes through fixed pin 5 and is connected with 1 frame of motor, it has two mounting holes to open near 4 one side of brake disc on the 1 frame of motor, spring 2 and electromagnetic device 3 are installed respectively to the mounting hole, the outside of brake disc 4, be provided with rolling disc 7 on the 1 main shaft of motor, install on the rolling disc 7 and stretch out rolling disc 7 and be close to the rolling pin 6 of 4 one sides of brake disc, brake disc 4 corresponds 6 positions of rolling pin and is equipped with the pinhole.
The electromagnetic generating device 3 is an electromagnetic coil or an electromagnet, and the electromagnetic generating device 3 is connected with an external power supply; preferably, in the present embodiment, the electromagnetic generating device 3 is an electromagnetic coil.
The fixed pin 5 and the rotating pin 6 are both spring pins which have good shearing resistance.
For weight reduction, the brake disc 4 is composed of an aluminum plate 401 and an iron plate 402, and the iron plate 402 is arranged on the side close to the base of the motor 1, and the aluminum plate 401 and the iron plate 402 are fixedly connected, preferably, in the embodiment, the fixedly connected manner is through a screw.
The working process of the utility model is as follows: when the motor normally operates, the electromagnetic device 3 is electrified to generate suction force to attract the brake disc 4 to move leftwards, the brake disc 4 is not in contact with the rotating pin 6, and the motor does not brake.
When the motor needs to brake, the electromagnetic device 3 is powered off, the electromagnetic attraction disappears, the spring 2 pushes the brake disc 4 to move rightwards, the brake disc 4 is in contact with the rotating pin 6, the rotating pin 6 is inserted into a pin hole formed in the corresponding position of the brake disc 4, the rotating pin 6 cuts the brake disc 4, meanwhile, the fixing pin 5 and the rotating pin 6 generate elastic deformation, the kinetic energy of the motor rotor is converted into cutting energy and the potential energy generated by deformation of the fixing pin 5 and the rotating pin 6, and the motor brakes.
