  • Patent number: 8415845
    Abstract: In a motor, a stator with a three-phase winding set and a rotor are located in an operation region of a motor casing having a side wall. An inverter circuit constructed with power modules is located in a control region that is located on the opposite side of the operation region across the side wall in an axial direction of the motor. Each power module has a pair of transistors and a common terminal connected to the pair of transistors. A lead of a winding corresponding to one phase and a lead of a winding corresponding to another phase extend in the axial direction to cross over from the operation region to the control region and are connected together to the common terminal of a corresponding power module.

  • Publication number: 20120286605
    Abstract: A drive unit used in an electric power steering device has a motor and a control unit. A motor wire of the motor has a terminal, which is engaged with a power board side terminal of the control unit to electrically couple the motor and the control unit. In such structure, the motor and the control unit may be electrically coupled and decoupled, without the use of a special tool. Further, a terminal holder is disposed on an opening of the motor by a first short protrusion and a second short protrusion, thereby coupling the terminal to the motor.
