Abstract
An actuator having a switched reluctance motor and a plunger assembly. The switched reluctance motor has a stator and a rotor. The stator has a plurality of stator poles and a plurality of stator windings. Each of the stator windings is wound about a corresponding one of the stator poles. The rotor is rotatable about an axis and has a plurality of rotor poles. The plunger assembly has a plunger and at least one spring. The plunger is co-axially received in the rotor and movable in an axial direction along the axis. The at least one spring is disposed in a force transmission path that includes the plunger and is configured to permit movement of the plunger along the axis in opposite axial directions. The plunger assembly is being driven by the rotor.
