A method (200) of controlling an electric motor (116) may include determining a desired torque at the electric motor (116). A current at a first phase (142) of the electric motor (116) may be calculated at a controller (166). The calculated current may be a current that results in supplying the desired torque at the electric motor (116). The controller (166) may compare the calculated current to a predetermined threshold current, and when the calculated current is greater than the predetermined threshold current, the controller (166) may reduce the calculated current to the predetermined threshold current and adjust a current in a second phase (146) adjacent to the first phase (142) of the electric motor (116) to continue to supply the desired torque at the electric motor (116).
