What are the common electrical faults and solutions for brushless motor motor manual stator slot paper machine?
Brushless motor motor manual stator slot paper machine common electrical faults and solutions are as follows:
First, the motor does not run
1、Power problem
Fault description: After turning on the power, the motor does not have any response. It may be that the plug is loose, the power cord is broken or the power switch is damaged.
Solution: Check whether the plug is inserted tightly, whether the power cord is broken, broken, if there is a problem, then replace the power cord; check the power switch, if it is damaged need to be replaced in a timely manner.
2、Motor winding failure
Fault description: The motor winding may be short-circuited, disconnected or grounded, resulting in the motor can not start normally.
Solution: Use a multimeter to measure the resistance of the motor winding to determine whether there is a short circuit or disconnection; megohmmeter to check the insulation resistance between the winding and the motor shell to determine whether it is grounded. If there is a fault, the motor winding needs to be rewound or replaced motor.
3、Controller failure
Fault description: the controller internal circuit failure, such as chip damage, capacitor failure, etc., can not normally output control signals.
Solution: Check whether the power indicator of the controller is bright, if possible, use an oscilloscope and other tools to detect the output signal of the controller. If the controller is faulty, you need to contact a professional to repair or replace the controller.
Second, abnormal motor operation
1, motor shaking or noisy
Fault description: The motor runs with obvious shaking, accompanied by abnormal noise. It may be that the motor bearing is damaged, the rotor is not balanced or the motor is not firmly installed.
Solution: Check the motor bearings, if worn or damaged, replace them in time; carry out dynamic balance test on the motor rotor, adjust or replace the rotor; check whether the motor mounting bolts are loose, re-tighten the installation.
2、Motor overheating
Fault description: The temperature of the motor is too high after running for a period of time, and even the odor appears. May be too large a load, poor heat dissipation or motor winding local short circuit.
Solution: Check whether the load carried by the motor exceeds the rated load, if necessary, can reduce the load; clean up the motor cooling fan and the dust on the heat sink to ensure good heat dissipation; use a multimeter and other tools to detect the motor winding, find the short-circuit point and repair or replacement of the winding.
Third, the control circuit failure
1, button switch failure
Fault description: press the start or stop button, the motor does not respond. May be the button internal contact oxidation, damage or poor line contact.
Solution: Disassemble the button switch, clean up the contacts or replace the button; check the connection line between the button and the controller to ensure a firm connection.
2、Relay failure
Fault description: The relay can not be properly absorbed or released, resulting in the circuit can not conduct or cut off. It may be that the relay coil is damaged, the contacts are eroded or the control signal is abnormal.
Solution: Use a multimeter to measure the resistance value of the relay coil to check whether it is damaged; observe whether the contacts are ablated, and replace the relay if there is; check whether the control signal of the relay is normal, and exclude signal source failure.
3、Line failure
Fault description: The wires in the control line may be broken, short-circuit or poor contact, affecting the normal operation of the equipment.
Solution: Use a multimeter to check the line section by section to find the fault; repair or replace the damaged wires to ensure that the line is connected reliably.
