Abstract
A motor, which has a braking function and is used in a linear actuator includes a main body, a rotation shaft, a braking means and a stopping means. The rotation shaft penetrates the center of the main body. The braking means includes a braking ring and a helical ring. The braking ring includes a plurality of curved plates. The helical ring surrounds outer edges of the curved plates. Each curved plate is put on the outer periphery of the rotation shaft. The stopping means is disposed between the main body and the braking means for restricting the rotation of any of the curved plates. By this arrangement, a better braking and decelerating function can be achieved.
Claims4
A motor having a braking function and used in a linear actuator, including:
- a main body;
- a rotation shaft penetrating the center of the main body;
- a braking means comprising a braking ring and a helical ring, the braking ring being constituted of a plurality of curved plates, the helical ring surrounding an outer edge of each curved plate, each curved plate being put on an outer periphery of the rotation shaft;
- and
- a stopping means disposed between the main body and the braking means for restricting the rotation of any of the curved plates;
- wherein the main body comprises a shaft tube, the shaft tube is put on the rotation shaft and fixed to the interior of the main body, and the stopping means includes an insertion hole provided in the shaft tube and a pin fixed to any of the curved plates and inserted into the insertion hole.
