What are the categories of motor losses?


5 Categories motor losses

1.Core - The energy required to magnetize the core.

  1. Stator - I squared R heating of the stator due to current flow in the stator winding.

3.Rotor - I squared R heating of rotor bars as induced current flows.

4.Friction and Windage - Bearing and air friction on the rotor shaft and cooling fan.

5.Stray load - Leakage reactance fluxes induced by the load current.
