Abstract
An electric motor for a vehicle includes a stator, a rotor and a plurality of independent bridge drivers. Each bridge driver supplies a portion of current to the electric motor. There may be a phase shift between each independent bridge driver. Optionally, each bridge driver delivers current at a slew rate that is different from each other independent bridge driver.
