Abstract

With increased interest in transportation electrification, the accurate modelling and analysis technique of AC copper loss plays a crucial role in the design. The distributed wound stator is dominant in electric car motors due to their suitable characteristic in the electric powertrain. The random wound-distributed windings are considered in this paper to analyze AC copper loss. The paper shows a case study with two different methods to calculate the AC copper loss for random windings and discusses each method’s merits and demerits. The first method uses a pure magnetic solver or decoupled approach, while the second uses a coupled magnetic and circuit solver.
