PROBLEM TO BE SOLVED: To provide aθZ actuator for realizing exact rotating operation and rectilinear operation with a single actuator having a simple structure. SOLUTION: TheθZ actuator comprises a mover 200 equipped with a permanent magnet 203 as a field magnet or iron teeth, and a stator 100 equipped with aθ-axis armature winding 102 for generating rotary magnetic field in a rotaryθ-axis direction and a Z-axis armature winding 103 for generating a progress magnetic field in a rectilinear Z-axis direction, wherein current is applied to theθ-axis armature winding 102 and the Z-axis armature winding 103, and a torque is generated in aθ-axis direction and a thrust force is generated in the Z-axis direction to execute the rotation operation and the rectilinear operation of the mover 200. In theθZ actuator, a hollow core portion of theθ-axis armature winding 102 is used as a crossover processing space 110a of theθ-axis armature winding 102 and the Z-axis armature winding 103.
