How to adjust the spring of permanent magnet DC motor?

When using a permanent magnet motor, it is necessary to change the spring to a certain extent. What are the methods of using the spring to adjust the permanent magnet motor? The following Vshida micro-motor will give you a brief introduction.

1. After opening the case and keeping the power off, loosen the screws of the case cover and remove the case cover.

2. Use a hex wrench to adjust each tension spring screw for optimal operation of the PM motor controller as the tension rod moves.

3. If the lever vibrates when it is just moved, the tension of the balance spring is too large, and the above procedure should be repeated.

4. After turning on the power of the gate, press the up and down keys of the controller to make the permanent magnet motor controller rotate four to five times. Just switch the controller of the permanent magnet motor to the vertical position.

5. If the motor controller starts when the lever is lifted, but the permanent magnet direct drive motor controller does not start, it means that the tension of the balance tension spring is insufficient. At this time, the state of the tension spring should be changed or hardened until the motor controller works normally.
