The stopping sequence of the motor power supply and brake po

The motor used as the driving source of the indexing gearbox realizes the function of intermittent motion and stop during the assembly and use of the indexing gearbox. Then, the automatic system in operation needs to frequently perform the motion and stop braking action on the motor. In order to ensure the timely and accurate braking positioning and effectively eliminate the inertia of the motor, most of them will use the brake motor.

The motor and the brake system have separate power lines. During use, customers will think that it is troublesome to connect the power lines separately. Connect the power line and the brake of the motor to the same power source. In this way, the motor can work normally, but, The brake does not work normally, and it does not achieve the expected effect of using the brake.

Therefore, the correct method is to separate the motor and the brake with different power sources. The motor and the brake are two different entities. The brake system works when the motor stops. The start and stop time of the brake power supply and the motor power supply can be delayed by 0.1 to 0.4. Seconds, generally in the case of inverter control, first stop the motor, and then start the brake. In this way, the service life of the motor can be effectively guaranteed.

The selection of the indexing gearbox needs to consider factors such as load, accuracy, speed, etc. In the selection of the motor, power is one of the main considerations. The role of the motor using the inverter is to ensure that the motor is within the rated power range. Adjust the motor speed to control the running speed of the indexing gearbox. Therefore, in the mechanical action of intermittent stop using the cam indexing gearbox, the inverter and brake used for motor control are commonly used components. In this case, there is no driving angle and angle of repose. In this way, the cam rotary indexer is equivalent to a reducer.
