Effect of Magnetic Properties of Magnetic Composite Tapes on Motor Losses
Energies, 2022 Alternating current (AC) copper losses in motors increase with carrier frequency of the pulse width modulation (PWM) and are further increased by leakage flux of the permanent magnet. Therefore, AC copper losses increase with motor speed.
