ABSTRACT:
An electric power steering removes external wiring connecting between an electric motor and a control unit, whereby the influence of radiation noise caused by a PWM operation can be reduced. In addition, the heat radiation and assemblability of the electric motor and the control unit can be improved, while achieving high power output. A housing64with a metal substrate61fixedly secured thereto is arranged at a side opposite to an electric motor30. The cooling fins are formed on an outer side of a housing64and on an outer side and an inner side of a cover65. A metal substrate61, a large current substrate62and a control substrate63are arranged inside of the housing64and the cover65in a laminated structure.
