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.
