PROBLEM TO BE SOLVED: To make a servo unit compact while enhancing heat dissipation of a motor.SOLUTION: A servo unit structure comprises: a servo case 10 consisting of a case body 11 and a lid member 12; and an inner rotor type motor 20 in the servo case 10. The case body 11 integrally has a concave motor chamber 10a into which the motor 20 is inserted in the axial direction, and a concave detector chamber 10b into which a detector 30 is inserted in the same direction. The lid member 12 is attached to the case body 11 so as to close the opening of the motor chamber 10a and detector chamber 10b. The motor 20 includes a cylindrical stator 20a not having a casing on the outer periphery, and a rotor 20b being inserted rotatably into the stator 20a. The stator 20a is brought into direct contact with the inner wall surface of the motor chamber 10a and fitted in place. |
