  • Publication number: 20140183993
    Abstract: An extended end portion (20) of a coil conducting wire (16) and an extended end portion (30) of a flat plate bus bar (35) are placed in parallel and adjacent to each other. The width of the bus bar (36) is wider than that of the coil conducting wire (16). On an end portion of the bus bar extended end portion (30), a tapered portion (44) is formed. Tip ends of the coil conducting wire extended end portion (20) and of the bus bar extended end portion (30) are welded to each other. As the tip end of the bus bar extended end portion is thin, welding heat is transmitted to a deeper position in the longitudinal direction of the bus bar, which results in a wider welding area. In addition, welded material flows along the slant surface of the tapered portion (44), which also results in a wider welding area.

  • Patent number: 8307929
    Abstract: First and second motors have structures different from each other. A control device estimates a first magnet temperature of the first motor and a second magnet temperature of the second motor and controls a drive unit based on the first and second magnet temperatures. The control device estimates the first magnet temperature using a first parameter (the temperature of cooling oil of the first and second motors) and estimates the second magnet temperature using the temperature of the stator of the second motor. Since an appropriate parameter is selected from among a plurality of parameters concerning the state of the first and second motors, the first and second magnet temperatures can be estimated more accurately.
