5 Categories motor losses
1.Core - The energy required to magnetize the core.
- 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.
