Servo motor is a typical closed loop feedback system, driven by a motor gear group, the terminal (outputs) to drive a linear potentiometer position detection, the proportion of the potentiometer Angle coordinate transformation into - proportional voltage feedback control circuit boards, control circuit board to be compared with the control of input pulse signal, produce correct pulse, And drive the motor to rotate forward or reverse, so that the output position of the gear set is consistent with the expected value, so that the correction pulse tends to be 0, so as to achieve the purpose of accurate positioning and speed of the AC servo motor.
Observe whether sparks are generated between the carbon brush and the commutator when the AC servo motor is running and the degree of sparks is repaired
1. There are only 2 ~ 4 small sparks, at this time if the commutator surface is flat, most cases can not be repaired.
2. No spark, no need to repair.
3. there are more than 4 small sparks, and there are 1 ~ 3 large sparks, it is not necessary to remove the armature, just use sandpaper to grind the carbon brush commutator.
4. If there are more than 4 big sparks, it is necessary to use sandpaper to grind the commutator, and the carbon brush and the motor must be removed to replace the carbon brush and grind the carbon brush.
The flange of the machine mounted with the HC-MF(HC-MF-UE)/HC-KF(HC-KF-UE)/HC-AQ/HC- MFS/HC-KFS must be connected to the earth.
