A power plant outputs motive power by driving a motor (22) using electric power from a direct-current power source (32). When the direct-current power source (32) has a low temperature, the direct-current power source is rapidly heated, whereby the perform...

A positive side conductor (3) and a negative side conductor (2) of an input terminal electrically connected to semiconductor elements, are electrically insulated from each other, and are laminated with each other, and the input terminal having such a lamin...

A controller (100) for a vehicle motor includes a switching unit (12), a capacitor unit (14), output terminals (15a, 15b, 15c) and wiring lines (15d, 15e, 15f). The switching unit (12) is provided on a substrate (11) to control power supply to a motor. The...

The invention provides a permanent magnet rotary electric motor as a starter-generator apparatus with which high driving torque is obtained when it functions as a starter motor whereas the driven torque can be suppressed low when it functions as a generato...
