[0078] see Figure 1 to Figure 4 According to the first embodiment of the present invention, a rotary actuator 1 includes a base 10, a first linear motor 20, a second linear motor 30, a first linear track 41, a ball screw 50, two A first linear slider 61 and a second linear slider 62.
[0079] In this embodiment, the base 10 is an elongated member. More specifically, the base 10 has a parallel and opposite first side 10A and a second side 10B, wherein the major axes of the first and second sides 10A and 10B are parallel to the Z axis defined in the figure, and the second side 1. A recessed elongated space R is formed on the second sides 10A and 10B respectively, the long axes of which extend in the Z-axis direction. In addition, the base 10 also has a third side 10C and a fourth side which are parallel and opposite 10D is parallel to and opposite to a fifth side 10E and a sixth side 10F, wherein the third to sixth sides 10C-10F are respectively located between the first and ...
