The braking function of Liming motor is mainly to decelerate, stop, reverse, or not rotate due to external force. There are two main modes - electromagnetic friction and mechanical friction.
Electromagnetic: The motor coil generates a reverse magnetic force to decelerate the motor. When the motor stops, the motor coil generates a magnetic force to prevent the motor from rotating.
Mechanical friction type: In general motors, the power supply will be cut off. The mechanical friction brake motor will install a mechanical brake pad (brake pad) at the end of the motor. When the motor is working normally, it will generate a magnetic force to pull the brake pad away from the contact. If When the motor is not energized, due to the action of the spring, the clutch plate will come into contact with the clutch plate installed on the tail shaft of the motor, so that the motor will not rotate without being energized.
Using reducer clutch braking, in fact, clutch and brake refer to two things: 1. Clutch refers to the combination or separation mechanism that transmits power to another shaft, called clutch. 2. Brake refers to the mechanism for stopping power .
Many mechanisms combine the two in the same mechanism, making it both the functions of a clutch and a brake, and become a brake clutch. Clutches, brakes, and brake clutches are divided into electromagnetic, mechanical friction and their combinations, just like motor mechanisms. The principle is the same as that of moving. The clutch transmits the power to another shaft or opening, and the brake transmits the power to a fixed rigid structure which counteracts the power by force.
Simply put, it is:
1. Motor braking is of course to stop the motor.
2. Start when you want to stop the motor.
3. The purpose of using the clutch brake is to prevent the Liming motor from starting and stopping all the time, which is generally used when starting and stopping are frequent.
The brake of Liming motor is usually placed in the motor. The size of the brake depends on the magnetic force or mechanism that the motor can generate, so the braking force is limited. Often the transmission force or braking force required by the equipment is generated by the various reducers or inertial mechanisms of the motor. This is why the brake clutch system is added to the motor. This brake clutch system is external to the motor and can be used according to the needs of the equipment to meet the transmission or braking force required by the equipment, so the general purpose of the motor is not used. brake.
