With the gradual improvement of the automation of daily life, the use of automatic doors has become more and more extensive. As a key part of the automatic door system, permanent magnet motor must have the advantages of high power density, fast response and low price. With the increasing power density of the permanent magnet motor, the magnetic field distribution inside the motor is more and more complicated, and the magnetic circuit structure is more and more abundant. The electromagnetic design using the traditional magnetic circuit calculation method is no longer applicable.
First, you must first keep the power off, open the chassis?, then loosen the screws on the cover, and finally remove the cover.
Second, use a hex wrench to adjust each of the tension spring screws so that the controller of the permanent magnet motor can achieve the best results when the rod is running.
3. If there is a jitter in the lever time lever, it means that the tension of the balance spring is too large. The above operation should be repeated at this time.
4. Connect the channel gate power supply, press the up or down button of the controller to make the controller of the permanent magnet motor run up and down 90 degrees 4 to 5 times. If the falling rod time bar appears to be shaking, it means that the balance spring tension is not enough. The controller of the permanent magnet motor can be operated to the vertical state.
5. If the controller of the motor is running when the lever is up, and the controller of the permanent magnet direct drive motor does not work, the tension of the balance tension spring is insufficient. At this time, we should adjust the tension spring state or increase the tension spring until The motor's controller is operating normally.
