Recently, a customer friend asked, the ordinary gear reduction motor used in the cam indexer does not need to brake, here is a sub-board and discussion.
Intermittent cam indexers mostly use ordinary gear reducer motors to meet the requirements of use, then, should the drive motor brake? First, let's analyze what the function of the motor is. The brakes used by the indexer motor are mainly used to control the inertia of the motor to achieve the required accurate positioning. In the case of the system issuing the stop and stop command to turn off the power, the motor itself is realized. Positioning control. The brake of the motor can play the role of clutch, inching, shifting, and reversing. When the motor uses the brake, the motor with the electromagnetic brake is more common in actual use. When the drive motor is energized and started to run (normally, the brake is energized before the motor is started), the brake is energized to release the brake, so that the motor restarts. . When the motor stops driving, the brake also stops powering and acts as a brake, causing the motor to stop running quickly. The general brake system and the electromagnetic brake coil are all coaxially mounted with the rotor of the motor.

From the above analysis, it can be seen that the brake of the indexer motor is very helpful for the precise positioning of the motor stop. Most of the automatic turntables are added to the automatic control system under the premise of the intermittent function of the indexer itself. Especially for some high-speed operation, at the same time, when the drive system is frequently stopped, the requirements for the performance of the motor are relatively high. Therefore, the use of the brake on the driving motor reduces the wear of the motor caused by the frequent movement of the motor. , it plays a role in reducing the precise positioning of inertia.
Speaking of this problem, you may ask, the indexer drive motor uses the brakes to have any effect on the indexer or the auxiliary function of positioning. The answer is completely wrong, because the indexer has its own self-locking function, its There is no relationship between the stop and the motor or the brake, including the accuracy. Only the motor is unstable due to the stability of the voltage, etc., which affects the indexer.
In summary, it is recommended that the cam indexer drive the motor to use the brake.
