摘要： In a related-art resolver, a front and a back of a stator core (3) cannot be distinguished, and it is difficult to mass-produce the resolver while matching directions of shear drops and burrs. Thus, assembly accuracy of the resolver is degraded. Further, productivity and assembling ability are degraded because electromagnetic steel sheets are laminated by rotary lamination. The present invention provides a resolver including: a resolver stator (2) including: a stator core (3) formed of electromagnetic steel sheets, which have teeth (3a), and are laminated without rotary lamination; a one-phase excitation winding; and two-phase output windings; and a resolver rotor (1) arranged to be opposed to the resolver stator (2), in which the stator core (3) has marks (3b) which enable distinction of a rolling direction of the stator core (3) and distinction of a front and a back of the stator core.

摘要： A rotary electric machine includes a rotary electric machine main body (2), and a controlling apparatus (3) that is disposed on the rotary electric machine main body. The rotary electric machine main body includes: a stator (4); a rotor (5) that includes a rotating shaft and that is rotatable relative to the stator; and a supporting body (6) that supports the stator and the rotor. The controlling apparatus (3) includes a power circuit portion that is disposed around the rotating shaft (12), and that converts electric power that is received from the rotary electric machine main body (2) or electric power that is supplied to the rotary electric machine main body (2) between alternating current and direct current. The power circuit portion includes: a power module that includes a switching element; and an electric power interconnecting part that includes a conductor that is connected to a terminal of the power module. The electric power interconnecting part is disposed so as to avoid overlapping with a region of the power module when the power circuit portion is viewed in an axial direction of the rotating shaft.

摘要： A control unit assembly A is located at a rearmost side, a brush unit assembly C is located at a frontmost side, and a power unit assembly B is located between the control unit assembly and the brush unit assembly, respectively. The control unit assembly, the brush unit assembly and the power unit assembly are incorporated in a rear bracket 5. The rear bracket, the control unit assembly, the power unit assembly, and the brush unit assembly are integrated to configure a rear side semi-manufactured assembly D. In a controller-integrated electric rotating machine configured to assemble a front side semi-manufactured assembly E formed from an electric rotating machine main body 1 and a front bracket 4 with the rear side semi-manufactured assembly D, a series of brush restricting pin insertion holes 24 are disposed from a rear side end surface of the control unit assembly through the brush. Assembling workability is improved without failures in assembling work which occur due to breaking away of a brush from a brush holder to the rotary shaft side.

摘要： An electric rotating machine is provided that efficiently radiates heat, caused in the vicinity of a portion where a brush and a slip ring makes contact with each other, to the outside of a brush holder and that can prevent the temperature of the brush from excessively rising. The brush holder holding the brush that supplies a magnetic-field current to a magnetic-field winding by way of the slip ring is provided with an energization terminal that electrically connects a magnetic-field circuit with the brush and a brush cooling metal member that cools the brush; the brush cooling metal member radiates heat, generated in the vicinity of a contact portion between the brush and the slip ring, to the outside of the brush holder.
