Abstract
An actuator including at least one moving body, at least one fixed body and a connecting member is provided. The moving body is suitable for moving along a direction, and includes at least one coil. In addition, the fixed body includes a permanent magnet and a yoke, wherein the coil is disposed between the permanent magnet and the yoke, and the polarity direction of the permanent magnet is parallel to the moving direction of the moving body. Furthermore, the connecting member is used for connecting the moving body and the fixed body. The actuator meets the requirements of miniaturization, low power consumption and low cost.
Claims11
An actuator, comprising:
- at least one moving body, suitable for moving along a direction, wherein each moving body comprises at least a first coil and a second coil;
