    Tips: How does the AC servo spindle motor realize speed control?

    AC servo spindle motor is a typical closed loop feedback system. The reduction gear set is driven by motor, and its terminal (output end) drives a linear proportional potentiometer for position detection. The potentiometer converts the corner coordinates into a proportional voltage and feeds it back to the control circuit board. The control circuit board compares it with the input control pulse signal, generates a correction pulse, and drives the AC servo spindle motor to rotate in the forward or reverse direction, so that the output position of the gear set is consistent with the expected value. The correction pulse tends to be 0, so as to achieve the purpose of precise positioning and constant speed of the AC servo spindle motor.

    Existing reviews of 5 hp (3.7 kW) AC Servo Spindle Motor, 24 Nm, 1460 rpm
    Nice AC Servo Spindle Motor
    Compared with my previous motor, I think this AC servo spindle motor's function of regulating speed has been greatly improved. It starts and corresponds very quickly. The structure is compact and easy to operate. Great performance of this servo motor and nice quality. It seems that I don't have to spend too much effort on maintenance in the future.
