In an AC servomotor constructed so that the outer circumference (21b) of a stator core (21) formed by laminating thin steel plates (22) is used as part of a motor housing, bearing mounting bores (25a, 26a) for receiving bearing members (27, 28) to be mounted on a pair of brackets (25, 26) attached to the front and rear ends of the stator core (21) and mounting surfaces (25b, 25c) of the motor are formed with accurate concentricity and squareness with reference to the center bore (21a) and the outer circumference (21b) of the stator core (21) after firmly joining the brackets (25, 26) to the stator core (21). Thus, a rotor (29) is supported with high accuracy in concentricity with the stator core (21) on the brackets (25, 26) and the squareness of the output shaft (29a) to the mounting surfaces (25b, 25c) is established. |
