The principle of motor brake pads:
1. The rear bearing end cover of the motor is equipped with a friction disc and excitation coil made of asbestos metal composite material. When the motor jumps to a stop, the friction disc is clamped by the brake spring and presses firmly on the produced plan view of the rear bearing end cover of the motor, which in turn causes the brake disc to cause strong friction torque to achieve braking. The purpose.
2. The clutch brake pad DC brake can not be connected to the AC power immediately. The brake glass suction cup is equipped with a winding electromagnetic coil, and the rated current of the winding is the bottom voltage AC voltage. When working, the single-phase asynchronous motor source must be supplied with a glass suction cup winding resistance after the rectifier, so an electronic rectifier is additionally provided in the brake motor terminal.
3. The braking time of the friction pad brake motor of the loader is the time that the motor and the brake terminate the power supply system in an instant, and the time it takes to completely terminate the shaft. Under normal conditions, the braking time of the motor with the motor shaft number of 63~80 is about 0.5 seconds, the braking time of the motor with the motor shaft number of 90~132 is one second, and the motor with the motor shaft number of 160~180 has a braking time. The moving time is about 2 seconds.
