In the process of production and use of the motor, there will be various reasons for failure; belowMori machineSmall series collected some aboutTorque motorThe common faults and troubleshooting methods at work are only for reference. If there are any questions or faults in use, you can contact the technical department of the company to solve them in time.
[1]
Symptom: Can not start, but there is a sound?
Possible causes:
1.Power line break
2.Motor internal wire break
Treatment method:
1.Check the line, find the break, fix it
2.Check the winding for breakage with the key table to determine whether to repair or rewind
【 2 】
Fault symptoms:Torque motorWhen starting, the starting torque is insufficient, and the speed is lower than(1/3)n?
Possible causes:
1.The power supply voltage is too low. Procedure
2.A phase break in the motor
3.Excessive load moment
4.Improper selection of deceleration ratio
Treatment method:
1.Check the supply voltage
2.Check the winding with the table
3.Check the load, check whether the stator core is on the right end
4.Check if the reduction ratio is too small and replace the reducer
【 3 】
Fault phenomenon: The motor is overheated and there is a sound when rotating?
Possible causes:
1.Excess load
2.undervoltage
3.Interphase winding short circuit or a set of two points around the pole ground
4.Motor at low speed is lower than (1/3)n
Treatment method:
1.Remove overload or replace largeTorque motor
2.Check the supply voltage
3.Check line voltage, determine short circuit and repair or rewind
4.Replace motors with a large number of poles, such as4Pole commutator6Pole; Change the pulley diameter or increase the deceleration ratio
【 4 】
Fault symptom: Insulation resistance is reduced?
Possible causes:
1.The environment is too wet and dirty, corrosive gases or harmful impurities
2.Motor insulation aging due to long-term overheating
Treatment method:
1.Use according to the specified conditions of use
2.Check insulation status to determine repair or rewinding
【 5 】
Fault phenomenon: bearing ring, overheating?
Possible causes:
1.Bearing wear has reached its limit
2.Bearing room is not clean, there are debris
3.Bearing grease is of wrong grade, bad quality, too much or too little
Treatment method:
1.Check the bearing and replace the broken bearing
2.Check bearing room, clean and remove debris
3.Check grease, replace, and quantity is appropriate
[6]
Failure phenomenon: mechanical vibration, motor torque is not enough?
Possible causes:
1.Improper installation or unstable foundation
2.The concentricity of the motor shaft and the driven shaft is abnormal and different
Treatment method:
1.Check the installation and correct it
2.Check concentricity with a dial gauge and correct
