Patent ID: 8456049

Claim:
A drive apparatus comprising: a motor having a motor case formed in a cylindrical shape to define an outer periphery, a stator located radially inside the motor case and including coils wound to provide a plurality of phases, a rotor located radially inside the stator and rotatable relative to the stator, and a shaft rotatable together with the rotor; a heat sink located in an axial direction of the motor case; a power module arranged on the heat sink to switch over current supply to the coils; a control circuit wiring part arranged on the heat sink and electrically connected to the power module to supply a control current for controlling the motor; a power circuit wiring part arranged on the heat sink at a position opposite to the control circuit wiring part and electrically connected to the power module to supply a drive current for driving the motor; a control circuit connector electrically connected to the control circuit wiring part to input and output the control current; and a power circuit connector electrically connected to the power circuit wiring part to input and output the drive current, wherein the control circuit connector and the power circuit connector are located between the control circuit wiring part and the power circuit wiring part.
