The following is a summary of common electrical faults and solutions for brushless motor motor manual stator slot wedge machine, the content is clear and concise, easy for operators to quickly troubleshoot the problem:


Brushless motor manual stator slot wedge machine common electrical faults and solutions


1. equipment can not start (no response)


Possible causes


Power supply is not connected or unstable voltage


Fuse blown


Emergency stop button is not reset or circuit breaks


Solution: Check the power plug, switch and supply voltage (normal range: 220V).


Check the power plug, switch and supply voltage (normal range: 220V±10%).


Replace the fuse with the same specification (power off operation is required).


Reset the emergency stop button, check whether the control circuit is disconnected, and test the line with a multimeter.


 


2. Abnormal motor operation (shaking, weakness)


Possible causes


Motor driver (controller) failure


Motor winding short-circuited or disconnected


Encoder signal interference or damage


Solution


Restart the drive and check the status of the indicator; replace the drive if necessary.


Measure the resistance of the motor winding with a multimeter; if it is abnormal, the motor needs to be returned for repair or replacement.


Check the encoder connection line, make sure the shield is grounded and the signal line is not interfered.


 


3. Sensor failure (position detection error)


Possible causes


Photoelectric / proximity sensor contamination or offset


Abnormal power supply to the sensor


Poor contact of signal wire


Solution


Clean the sensor surface and adjust the sensing distance to the standard value (refer to the manual).


Measure the sensor power supply voltage (usually DC 12-24V) with a multimeter.


Re-plug the signal cable connector, or replace the damaged cable.

4. Frequent overload protection


Possible causes


Excessive motor load (e.g. slot wedge too tight or jammed)


Incorrect setting of drive parameters


Poor heat dissipation leading to overheating


Solution


Check whether the mechanical parts are jammed, adjust the slot wedge pressure or lubricate the moving parts.


Check whether the drive current and speed parameters match the motor nameplate.


Clean up the drive and motor heat sink to ensure normal ventilation.


 


5. Control panel display abnormality (garbled code / no display)


Possible causes


Control panel power supply failure


Loose wires on the display


Program error or memory failure


Solution: Check whether the DC 5V/24V power supply of the control board is normal.


Check whether the DC 5V/24V power supply of the control board is normal.


Re-plug the display wires to make sure the contact is firm.


Power off and restart the device, if still abnormal, contact the manufacturer to upgrade or replace the control board.


 


Daily Maintenance Recommendations


Regular Inspection: Clean the electrical cabinet monthly and tighten the terminals.


Preventive measures: Avoid running the equipment in humid and high temperature environment.


Record faults: Record the fault phenomenon and treatment, to facilitate the subsequent rapid troubleshooting.


 


Through the above steps, can quickly locate and solve most electrical problems
