Abstract
Reluctance-based resonant linear motors and methods of operation are provided. An example linear motor includes a spring having a plurality of coils. The linear motor includes a stator coaxially surrounding at least a portion of the spring. The stator includes a plurality of teeth. The linear motor includes a plurality of windings respectively positioned within a plurality of winding cavities respectively formed by the plurality of teeth. The application of electrical energy to the plurality of windings generates a magnetic field that flows through one or more of the coils of the spring. The flow of the magnetic field through the one or more coils of the spring causes the spring to actuate towards a compressed position. An example method includes periodically applying electrical energy to the plurality of windings such that the spring oscillates at a resonance frequency associated with the linear motor.
