Rotor flux control in a permanent magnet (PM) electric machine involves controlling fluid flow through the rotor based on the torque versus speed operating point of the PM machine. When the torque at a given speed falls below a predetermined threshold, the rotor receives a reduced fluid flow compared to when the torque is above the threshold. Fluid flow through the stator is controlled in an inverse manner relative to the rotor's fluid flow such that when the rotor experiences reduced fluid flow, the stator receives an increased fluid flow. This approach enables efficient control of the rotor's magnetic flux, enhancing the performance and efficiency of the PM electric machine during various operating conditions.
