A frame is an aluminum die-cast product and includes a frame main body and a frame hole. The frame main body is placed at an inside of an opposite part of a case tubular portion, which is opposite from a case bottom portion. An outer wall of an outer peripheral portion of the frame main body is opposed to an inner wall of the case tubular portion. A receiving space is formed by the frame main body, the case tubular portion and the case bottom portion. The frame hole is formed in a center part of the frame main body. A stator is received in the receiving space. A rotor is rotatable together with a shaft. A seal member is placed between the case tubular portion and a housing of a rack gear and can liquid tightly seal between the case tubular portion and the housing.

In a rotary electric machine having an integrated drive control device, a motor housing joined to a mounting housing, which is a cast member, is made of a steel material. Therefore, an outer diameter is reduced and strength for retaining a stator core is satisfactorily ensured even under high-temperature environments.

A segmented component for a housing includes a first shaped part, a first segment having a first cast metal region which is material-bonded to the first shaped part by a first bonding zone. The first shaped part is material-bonded to a second cast metal region of a second segment by a second bonding zone. At least one additional element is material-bonded to the second segment by a third bonding zone and material-bonded to the first segment by a fourth bonding zone, wherein the first shaped part, the first and second segments, and the at least one additional element defining an extension of an interior space of the housing in a cross-sectional plane.

A motor is contained in a motor container space. A controller is contained in a controller container space. The motor container space and the controller container space are arranged in series in a direction of a rotation axis of a motor shaft, while interposing a partition wall therebetween. The motor shaft is inserted in a motor shaft through-hole of the partition wall. A magnet is disposed at an end of the motor shaft, in the controller container space. A rotation sensor is disposed in the controller container space oppositely to the magnet, for monitoring a rotational position of the motor shaft on the basis of variation in magnetic field due to rotation of the magnet. A cover made of nonmagnetic metal is disposed between the magnet and the rotation sensor so as to cover the motor shaft through-hole.
