The working principle of the brake safety brake

                                             The working principle of the brake safety brake

1, the structure of the electromagnetic brake brakes brake:

Is mainly composed of two parts: brake electromagnet brake and brake shoe.

Brake electromagnet by core, coil and armature of three parts. Brake shoe brake including brake drum, brake shoe, and spring etc, brake wheel and motor installed on the same axis.

2, the working principle of the electromagnetic brake brakes brake: motor power, and electromagnetic brake coil electricity, armature and, to overcome the tension of the spring brake shoe and brake wheel, motor function. Disconnect switch or contactor, motor power, electromagnetic brake coil also lost electricity at the same time, the armature to separate from the core, under the action of a spring tension and make brake shoe hug brake wheel, motor is braking and halt.

3, the characteristics of the electromagnetic brake brakes brake

Mechanical brake mainly adopts the electromagnetic brake, electromagnetic clutch brake, both magnetic field generated by electromagnetic coil after electrify make the static iron core produces enough suction and armature or moving iron core (electromagnetic clutch of moving iron core is sucked, dynamic and static friction piece separately), to overcome the tension of the spring and meet the requirements of the job site. Electromagnetic brake is to rely on the brake shoe friction disc brake wheel. Electromagnetic clutch is the use of dynamic and static friction piece immediately when the power is enough friction between motor brake.

Advantages: electromagnetic brake braking, braking force is strong, widely used in lifting equipment. It is safe and reliable, won't because suddenly loses power and accident.
