This efficiency of motor is affected by the losses which include copper losses, mechanical losses due to friction, iron losses due to dissipation of magnetic energy in core and different losses depending upon type of material used.

To improve the efficiency these losses in the motor are required to be reduced during the design stage:

  1. Providing more fins for cooling of motor.
  2. Another basic tip is to keep minimum gap between any walls positioned near the back of the fan cover to allow air intake. Keep motor surroundings clean and periodically check for any air blockage that can reduce the cooling system performance. So the more cool motor will be running, it will be having more life span.
  3. Increase the cross section of winding wire to reduce the copper losses in Stator.
  4. reduction in Rotor losses by using copper bars in rotor.
  5. Using improved quality of steel in core - reduction in hysteresis loss.
  6. By reducing the thickness of lamination and increasing the length of lamination ,can minimize the flux density also and core losses.
  7. Eddy current losses can be largely minimized by ensuring proper insulation between the sheets or laminations used.
  8. Reduction in air gap
