Abstract
An actuator is provided, which includes a stator, a rotor passing through the stator and rotated in an interaction with the stator upon supply of external power, a driven body operating in accordance with a rotation of an axis of the rotor, a case surrounding the stator such that the axis of the rotor is protruded, and one or more rotation angle regulators installed on an outer side of the case and regulating a rotation angle of the rotor. Further, an electronic device having the actuator mentioned above is also provided.
Claims14
An actuator, comprising:
- a stator;
- a rotor passing through the stator and rotated by interacting with the stator upon supply of external power;
- a case surrounding the stator such that an axis of the rotor is protruded;
- and
- one or more rotation angle regulators installed on an outer side of the case and configured to regulate a rotation angle of the rotor, wherein, after the rotor is rotated, the rotation angle regulators cause the rotor to return an initial position under elastic recovery force by using an elastic member connected to the axis of the rotor protruding from one end of the case.
