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.
