A method of controlling an electric motor may include determining a desired torque at the electric motor. A current at a first phase of the electric motor may be calculated at a controller. The calculated current may be a current that results in supplying the desired torque at the electric motor. The controller may compare the calculated current to a predetermined threshold current, and when the calculated current is greater than the predetermined threshold current, the controller may reduce the calculated current to the predetermined threshold current and adjust a current in a second phase adjacent to the first phase of the electric motor to continue to supply the desired torque at the electric motor.
