Abstract:
A motor includes a rotating shaft, a rotor, a stator, a bracket, and a control device mounted on the bracket. The bracket includes a cylindrical bracket main body, and a stator frame which faces the bracket main body across a clearance and holds an outer surface of the stator on the radially inward side of the bracket main body. The control device is mounted on the bracket main body. The bracket is provided with a cooling passage, and an inflow port and an outflow port connected with the cooling passage. The cooling passage includes a control device cooling passage provided between the bracket main body and the control device, a stator cooling passage provided between the bracket main body and the stator frame, and a communication passage coupling the control device cooling passage and the stator cooling passage.

Claim (Index 1):
A motor comprising:\n a rotating shaft extending in a central axial direction; a stator including a core back concentric with the rotating shaft; and a bracket housing the stator; wherein the bracket includes a cylindrical bracket main body, and a stator frame which faces the bracket main body and holds an outer surface of the stator on a radially inward side of the bracket main body, the bracket main body and the stator frame being defined by separate members; the bracket is provided with a cooling passage through which a cooling medium is able to flow, and an inflow port and an outflow port connected with the cooling passage; the cooling passage includes a first portion provided directly adjacent to a radially outermost surface of the bracket main body, a second portion provided radially between a radially innermost surface of the bracket main body and the stator frame, and a communication passage coupling an output of the first portion and an input of the second portion with each other; a cooling medium in the first portion and a cooling medium in the second portion flow in opposite circumferential directions with respect to one another; at least a portion of the communication passage is located at a position which is farther outward in a radial direction than any portion of the second portion such that the communication passage does not overlap a radially inner surface of the stator cooling passage when viewed in a direction extending along the communication passage; and a portion of the communication passage and a portion of the core back overlap one another when viewed from a radial direction which is orthogonal to both the central axial direction and the direction extending along the communication passage.
