In a typical inverter-fed AC drive system, the stator windings carry current with large harmonics content, resulting in an increased loss. this paper, additional copper losses caused by non-sinusoidal currents are investigated for different magnet wire topologies, including flat conductor, stranded, and litz wires. Also, two-slot simplified model is introduced accurate prediction of at high frequency. It found that one major issues conventional coil not uniformly distributed across slot, over 70% concentrated near slot opening. Moreover, using transient finite element method, winding topologies arrangements simulated stranded level to evaluate density each strand under highly distorted currents. Furthermore, samples prototyped same geometries compare their performance pulse-width modulation (PWM) waveforms wide range frequencies. Finally, new hybrid proposed, which employ wires or materials within slot. The results demonstrate utilizing mixed configuration can effectively mitigate adverse effects eddy losses. This approach yield up 16–41% lower while also achieving weight savings 36–70%.
