We connected the motor according to the above wiring method, and the motor can operate normally. However, as for the wiring of the feedback signal, we do not understand it. Moreover, our wiring method still has certain problems, as the pulse frequency suitable for speed regulation of this motor is between 1000HZ-26000HZ. For every increase in frequency of 1000 HZ, the motor's speed increases by 150 revolutions, which is very accurate, But we found during the machine test that when the frequency was below 16000 Hz, it was not possible to start according to our wiring method. We used the last positive electrode of the starting wire as the starting method, but only when the frequency was between 16000HZ-26000HZ can we effectively start. After startup, the frequency can be adjusted between 1000HZ-26000HZ, which can adjust the speed. \u003cbr\u003eThis is just a strange thing, it can start even when the input pulse is below 1000Hz, and it can start normally when the input frequency is between 16000HZ and 26000HZ. The intermediate pulse frequency (1100-16000HZ) will shake when starting, but it cannot start.
