Definitions

  • the power electronics device (5) is a diagram of an electric motor (3) and a transmission device (4). It is placed across the middle and upper sides. Therefore, in the electric drive unit (1) of Patent Document 1, the dimensions of the entire electric drive unit (1) in the axial direction are those of the electric motor (3), the transmission device (4), and the power electronics device (5). It tends to be relatively large according to the sum of the arrangement areas in each axial view.
  • the vehicle drive device 100 includes a rotary electric machine 1, a pair of output members 6 that are driven and connected to a pair of wheels W (see FIG. 1), and a pair of output members 6 that are driven and connected to the rotary electric machine 1. It is provided with a transmission mechanism 3 for transmitting a driving force between the two, and an inverter device 90 for driving and controlling the rotary electric machine 1.
