Abstract
According to one embodiment, an electric actuator is provided comprising windings constructed from a conductive core of high magnetic permeability material surrounded by an electrical insulator. The conductive core simultaneously carries an electric current and a magnetic field, resulting in an actuator that can develop a high force or torque for its size compared to conventional electric actuators.
