The present invention achieves both highly accurate positioning control and high-speed speed control. The present invention is provided with a high-resolution encoder (11) for positioning control, and a low-resolution encoder (21) for speed control. The present invention also includes: position control means (13, 14) for generating a speed command in accordance with the difference between a given position command and a detected position based on the output of the high-resolution encoder; and speed control means (23, 24) for generating a current command in accordance with the difference between the speed command and a detected speed based on the output of the low-resolution encoder. The speed control cycle for the speed control means is set to be faster than the position control cycle for the position control means.
The purpose of the present invention is to detect the absolute rotation angle of a rotor in a simple manner. In order to detect the rotation angle of a rotor of a stepping motor including a rotor and stator windings, a first magnetic sensor (151) having a resolution of 200 steps per mechanical angle of 360° detects the rotation angle of a rotor. An incremental encoder (60) outputs a plurality of types of signals periodically in accordance with the rotation angle of the rotor. A rotation angle acquisition unit (122) in a control unit (102) acquires the absolute rotation angle of the rotor on the basis of the rotor rotation angle detected by the first magnetic sensor (151) and the type of signal outputted by the incremental encoder (60).

An actuator comprises: a housing which is provided with an opening; a slider which is installed so as to be movable relative to the housing; a drive means which is installed in the housing and which moves the slider; at least a pair of seal members which is disposed at the opening of the housing so as to face each other and which exhibits dust-proof and drip-proof functions by engaging with each other; and move-through members which are mounted to both sides of the slider in the movement direction thereof and which move through the pair of seal members. The move-through members each comprise: a move-through section which pushes apart the pair of seal members in the direction in which the pair is separated; a cover section which covers an expanded opening formed between the pair of seal members when the pair is pushed apart by the move-through section; and an opening restriction section which, when the pair of seal members is pushed apart from each other by the move-through section, restricts the amount of opening between the pair of seal members and in turn restricts the size of the expanded opening.

The purpose of the present invention is to provide an actuator such that egress of a lubricant to the outside of a housing during forward and rearward movement of a rod is prevented. The actuator comprises: a housing having a rod through-hole; a rod which passes through the rod through-hole such that a portion thereof protrudes to the outside of the housing and is driven forward and rearward; a first rod sealing member which is arranged near the outside of the housing in the rod through-hole; a second rod sealing member arranged near the inside of the housing in the rod through-hole; a lubricant supply part provided in the housing and supplying lubricant to the rod through-hole; and a pressure change absorption groove which is provided between the first rod sealing member and the second rod sealing member in the rod through-hole to communicate with the lubricant supply part, and forms an air layer while absorbing the pressure changes associated with the forward and rearward movement of the rod.
An actuator (10) includes a guide apparatus (30) that guides a rod 11 in a Y-axis direction. The guide apparatus (30) includes a slider (31), a rail (60) formed of a steel material, and balls (rolling elements) formed of a steel material. The slider (31) is supported by the rail (60) through the balls. Accordingly, even if torque originating from a rotation of the output shaft of a motor unit (20) is applied to the slider (31) through a ball screw shaft (71), the slider (31) does not move around the output shaft with respect to the rail (60). Hence, torque originating from the rotation of the output shaft is not likely to be transmitted to the rod (11) through the guide apparatus (30), thereby suppressing an occurrence of the wobbling of the leading end of the rod (11). In addition, a reduction of the work precision of the actuator (10) is preventable.

The actuator (10) comprises a guide device (30) that guides a rod (11) in the y-direction. Said guide device (30) is provided with a sliding part (31), a rail part (60) obtained from a steel material, and balls (rolling bodies) obtained from a steel material. The sliding part (31) is supported by the rail part (60) via the balls. As a result, even if a torque arising from rotation of the output shaft of the motor unit (20) is applied on the sliding part (31) via the shaft (71) of the ball screw, the sliding part (31) does not move around the output shaft with respect to the rail part (60). Therefore, it is more difficult for torques arising from rotation of the output shaft to be transmitted to the rod (11) via the guide device (30) and deflection of the tip of the rod (11) can be limited. Reduction in work precision of the actuator (10) can also be prevented.
