Abstract

An electric vehicle includes an electric motor switchable between a first mode with a first number of poles and a second mode with a second number of poles less than the first number of poles, a plurality of inverters coupled to the motor, and a control module coupled to the plurality of inverters. The control module receives current vehicle information, determines that a mode switch is required between the first and second modes of the motor based on the current vehicle information, wherein the first mode achieves higher torque than the second mode, and performs the mode switch by controlling the plurality of inverters.
