Embodiment Construction
[0024] Please refer to Figure 1 to Figure 3 , the initial calibration method of the arc segment motor control system of a kind of telescope of the present invention, comprises the following steps:
[0025] Step S1. Calibrate the positive direction of the electrical angle rotation of the motor and be consistent with the positive direction of the encoder rotation: take the clockwise rotation direction of the turntable of the telescope as the positive direction, which is the positive direction of the encoder rotation, and also the positive direction of the electrical angle rotation of the motor ; When the motor rotates in the positive direction at the electrical angle of the motor, the U opposite electromotive force of the motor leads the V opposite electromotive force of the motor by 120°, and the V opposite electromotive force of the motor leads the W opposite electromotive force of the motor by 120°;
[0026] Step S2, electrical angle calibration of the motor: the zero-crossi...
