Stray load losses are small, difficult-to-measure losses that occur when a motor is under load. These losses are not directly accounted for in the standard categories like copper loss or core loss.
Primary Causes of Stray Load Losses
- Leakage fluxes: Magnetic flux that doesn’t follow the intended path can induce eddy currents in nearby conductors or structures.
- Harmonic effects: Harmonics in the current can generate additional core losses and eddy currents, especially in the stator and rotor.
- Slot harmonics and saturation: These create localized heating and additional losses.
