1. Check the armature carbon brush, the length of the carbon brush, the contact surface and the elastic force are suitable;
2. Check the reversing ring, the surface should be flat, no dents, no damage, and the groove is not short-circuited by the toner;
3. Check that there is no problem with the coupling part of the speed measurement feedback component and the motor non-load measurement.
4. Check if there is any problem with the motor gear box. If the oil leakage, lubrication is poor, and the transmission mechanism is worn, the load may be unstable and the governor may be adjusted frequently.
If it is an analog speed control system, it will be more difficult for general electrical maintenance personnel, but still have to be handled as follows:
1. Measure whether the excitation provided by the governor to the motor meets the requirements of the motor and is stable. Generally, it should be constant to ensure the stability of the magnetic field. This is an advantageous condition for constant speed;
2. Measure the armature voltage to determine its range of variation; (for a given, generally about 40% of the maximum given)
3. Measuring the feedback voltage of the tachogenerator under the above conditions;
4. Measuring the current of the motor under the above conditions;
5. Observe the motor load to observe the change of motor speed. If the load increase speed changes significantly, IMAX should be increased; if there is no obvious change, go to the next step;
6. Adjust the feedback gain (increase or decrease to see if there is any change). If there is no change, return to the pre-adjustment position and proceed to the next step;
7. Adjust the speed loop proportional gain and integrate the capacitor to make the speed stable;
8. Re-setting the current loop parameters;
9. Test the car in all setting ranges and make fine adjustments to keep the speed stable under all speed segments and any changes in load;
10. Production test run to confirm that it meets its process requirements. Complete the repair according to the requirements, do not meet, adjust the parameters as needed.
