Current Profile Strategy for Minimizing Torque Ripple and Current

A system for controlling an electric motor, the system comprising:

• a switching bank configured to individually control current in each of a plurality of phases of a stator in the electric motor;
• and
• a controller configured to:
• determine a desired torque to be produced by the electric motor;
• calculate a current during a first phase of the electric motor required to supply the desired torque;
• determine whether the calculated current during the first phase is greater than a threshold current for the first phase;
• when the calculated current is greater than the threshold current, limit the calculated current during the first phase to the threshold current;
• and
• increase a current in a second phase of the stator adjacent to the first phase to at least partially compensate for a shortfall of torque at the first phase resulting from limiting the calculated current during the first phase.
