Motor Description

Common faults and troubleshooting methods are as follows when this series of motor fails during the operating process.

If the motor shell is live, reasons may be:
1) bad grounding;
2) damp winding, insulation damage or dirt on the terminal board;
3) frayed lead wire.
Relevant solutions are:
1) check ground connection;
2) winding drying, repair insulation damage and clean the wiring board;
3) repair or replace the insulated wire.

If the motor has abnormal sound at operating, possible reasons are:
1) motion of defective phase;
2) bearing damage and lack of oil;
3) mechanical rubbing or rubbing between stators and rotors;
1) check electrical connections and eliminate phase failure;
2) replace the bearing or grease;
3) check the stator bore for any debris such as paint lump, then process.

If the motor has abnormal vibration during operation, reasons are:
1) loose installation of motor or load;
2) the coupling or pulley is eccentric or unbalanced;
3) the shaft is bent after impact;
4) poor rotor balancing.
When facing this condition, solutions are:
1) check and fasten the foot bolt;
2) calibrate the eccentricity or rebalance;
3) replace the rotor or shaft;
4) rebalance.
