Abstract
A dual-winding electric motor for an electric vehicle includes a stator core including multiple teeth, multiple slots defined between the multiple teeth, a first set of stator windings wound in a first portion of the multiple slots, a second set of stator windings wound in a second portion of the multiple slots, and a control module is configured to supply a first pulse-width-modulation (PWM) signal to the first set of stator windings and a second PWM signal to the second set of stator windings. The first PWM signal has a different phase than the second PWM signal and the dual-winding electric motor operates according to PWM interleaving, and the first portion of the multiple teeth having the first set of stator windings is spatially separated from the second portion of the multiple teeth having the second set of stator windings.
