摘要： A stator (10) for a rotary electric machine has a tooth (14) whose width in a circumferential direction is substantially constant in a radial direction of the stator (10), and a concentrated winding coil (20) including winding conducting wires (21 to 26) around the tooth (14). A height (H2) of a first conducting wire (26) of the sixth turn at a tooth's (14) top end (15) side measured from a surface (17) of the tooth (14) is lower than a height (H 1 ) of a conducting wire (25a) adjacent to a tooth's (14) root end (16) side of the conducting wire (26a) measured from the tooth surface (17). Conducting wires of the first to fifth turns, that is, second conducting wires (21 to 25), have the same height (H 1 ) from the surface (17) of the tooth (14).

摘要： A device for estimating an internal temperature of an electric motor (MG). The electric motor (MG) has a stator core (22) extending cylindrically in a direction of an axis (CL) and around which a coil (28) is wound, a rotor arranged rotatably around the axis (CL), and a case (70) that houses the stator core (22) and the rotor (30), the coil (28) being cooled by a first cooling liquid (OIL) in the case. The device estimates the internal temperature by using a thermal circuit that regards a temperature of the first cooling liquid after heat reception from the coil (THoil1) as a first temperature equal to a temperature of the case (70).
