Closed-loop gains are determined based on these characteristics. The excitation signal may be sampled and a peak value in each interval may be identified and stored to produce an envelope of peak values for determining the gain response. Operation of the motor is controlled using the determined gains.

A rotor assembly for an electric machine includes a rotor core that is fabricated from a plurality of laminations stacked along a rotational axis of the electric machine. The rotor core has a plurality of arcuately arranged, axially extending magnet-receiving slots. The rotor core includes a plurality of magnets received in respective ones of the magnet-receiving slots. Each of the laminations includes opposed deflectable magnet-retaining prongs that extend into a corresponding one of the magnet-receiving slots. The magnet-retaining prongs are deflected by and engage the magnets to exert a reactive force against the magnets and hold them in place. Each of the laminations also includes respective support posts axially adjacent the magnet-retaining prongs. The support posts extend alongside and thereby limit the deflection of the magnet-retaining prongs when engaged with the corresponding one of the magnets.
