Jiaozuo brake

There are many classifications of brakes, including type parking brakes, parking brakes, and motor brakes.

So what is a motor brake, there's no need to say more. What are the functions of motor brakes?

The electrode may be dragged by the load during parking and may occasionally be in a power generation state. Simply put, it is in a power generation state when the speed and torque direction are opposite. At this time, the motor will convert mechanical energy into electrical energy.

Assuming that the equipment controlling the motor can only absorb energy from the grid and cannot send it back to the grid, the motor brake is needed to consume some of the remaining energy.

When the brake motor is powered on, the motor and brake coil are energized together. At this moment, the magnetic disc of the brake overcomes the pressure of the tension spring and is attracted to the side of the magnetic pole group, causing the conflicting plate to detach from the brake plate, allowing the motor to start.

When the power supply is cut off, the magnetic disc is pushed out by the tension spring due to the disappearance of the magnetic field, causing the conflict plate on the magnetic disc to collide with the brake plate, and quickly braking the motor.

Some people may ask about the function of the brake and clutch on the motor.

The brake is used to park the machine immediately after the power outage of the electric motor, so that the machine stops in the direction it should be stopped without causing too much erroneous travel. There are several types of clutches, such as separate clutches, which can separate some of the automatic transformation machinery from the forced transformation machinery. When operation is required, the clutch can be closed to operate, avoiding the harm caused by frequent starting of the motor. Another type is the overrunning clutch. It is a mechanical protection device that, when forced to overload some machinery, the overrunning clutch will slip, so as not to cause excessive damage to the machine
