What are the common electrical failures and solutions for brushless motor motor automatic stator press end plate machine?
Brush motor motor automatic stator press end plate machine common electrical faults and solutions are as follows:
First, motor failure
1, the motor does not start
Failure causes: power failure, such as power outage, power line disconnection, loose plug, etc.; motor winding burnt or short circuit; motor overload protection device action; controller failure, not output start signal.
Solution: check whether the power supply is normal, repair or replace the damaged power cord, plug tight; using a multimeter to detect the motor winding, if there is a burnt or short-circuit situation, need to replace the motor; check whether the load is too heavy, wait for the overload protection device reset, or to adjust the load; check the output signal of the controller, repair or replace the controller.
2, motor running noise or vibration
Failure causes: motor bearing wear or damage; motor rotor imbalance; motor winding local short-circuit or disconnection; motor installation is not solid.
Solution: Replace the worn or damaged bearings; motor rotor dynamic balance correction; using professional instruments to test the motor winding, repair or replace the problematic winding; re-tighten the motor mounting bolts to ensure that the installation is firm.
Second, the controller failure
1、No display of the controller
Failure causes: controller power failure, such as power adapter damage, internal power circuit failure; display damage; controller motherboard failure.
Solution: check whether the power adapter is working properly, measure the output voltage is normal, if damaged, then replace; check whether the display connection is loose, if the display is damaged, need to be replaced; test the controller motherboard, repair or replace the faulty motherboard.
2, the controller output signal abnormality
Failure causes: controller internal program error; controller input signal is abnormal; controller electronic components are damaged.
Solution: re-download or update the controller program; check whether the input signal lines and sensors are normal, to ensure that the input signal is correct; the use of professional tools to detect the controller's electronic components, such as chips, capacitors, resistors, etc., to replace the damaged components.
Third, the sensor failure
1, sensor no signal output
Failure causes: sensor damage; sensor power failure; sensor installation location is not appropriate, be covered or offset.
Solution: use a multimeter and other tools to detect the sensor, if it is damaged, then replace it; check the sensor power supply lines and supply voltage, repair or replace the power supply; adjust the sensor installation position to ensure that it can normally detect the target object.
2、Sensor malfunction
Failure causes: sensor sensitivity is not set properly; the surrounding environment has interference, such as electromagnetic interference, light interference, etc.; sensor surface dust or debris.
Solution: Re-adjust the sensor sensitivity, so that it reaches an excellent detection state; shielding of the sensor line, or change the sensor installation location to avoid interference sources; clean the sensor surface to ensure its detection accuracy.
Fourth, drive failure
1, drive alarm
Failure causes: drive over-current, over-voltage, overheating protection; motor parameter setting errors; drive and motor connection line failure.
Solution: check whether the motor load is too large, resulting in overcurrent, check whether the power supply voltage is stable, whether there is overvoltage, check the drive heat dissipation to ensure that the heat dissipation is good; reset the correct motor parameters; check whether the connecting line is loose, disconnected or short-circuited, repair or replace the line.
2、Drive output is not stable
Failure causes: drive internal electronic components aging or damage; drive power ripple is too large; electromagnetic interference.
Solution: test the drive, replace the aging or damaged electronic components; check the drive power supply, increase filter capacitors and other measures to reduce power ripple; drive and motor lines for shielding and grounding to reduce electromagnetic interference.
