Patent ID: 8299657

Claim:
A linear motor, at least including an electrically controlled actuator and an elastic member, the electrically controlled actuator at least comprising: a fixed element, a movable element positioned within the fixed element, and an electrical unit positioned around the outside of the movable element; and the elastic member at least comprising: a fixed portion, an elastic portion linked to the fixed portion, a movable portion linked to the elastic portion, and a pair of power supply terminals linked to the fixed portion, wherein the elastic member is positioned between the fixed element and the movable element of the actuator, the elastic member electrically communicates with the electrical unit of the actuator, the fixed portion of the elastic member is connected to the fixed element of the actuator, the movable portion of the elastic member is connected to the movable element of the actuator, and the thickness of the fixed portion is different from that of the elastic portion; and wherein power from an external power source is input to the electrical unit through the pair of power supply terminals that leads to an axial displacement of the movable element of the actuator and a linear displacement of the elastic portion of the elastic member.
