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.
