Abstract
An electric machine includes a rotor including a channel defined between a pair of magnets and a bridge assembly within the channel. The bridge assembly includes a bridge element and a spring arranged to bias the bridge element toward a center of the rotor such that responsive to spinning of the rotor, the bridge element moves radially away from the center against a force of the spring to alter a magnetic flux pattern associated with the magnets.
