Abstract:
1. A motor for controller integrated electric power steering apparatus comprising: a motor for generating assist torque with respect to a steering wheel of a vehicle; a controller which drives and controls this motor and is accommodated in a case; and a resolver which detects a rotational angle of a motor shaft of the motor and is accommodated in the case, wherein the motor, the controller and the resolver are formed integrally in a motor shaft direction, and the motor for controller integrated electric power steering apparatus is mounted in a speed reduction mechanism for reducing a speed of rotation of the motor and also is placed substantially coaxially in order of the motor, the controller and the speed reduction mechanism in the motor shaft direction, the motor for controller integrated electric power steering apparatus, further comprising: a driving substrate having a power element is arranged in the side of the speed reduction mechanism of the inside of the case; and a control substrate for controlling driving of the driving substrate is arranged in the side of the motor of the inside of the case, wherein the resolver and a lead frame comprising connection wiring are arranged between the control substrate and the driving substrate in the motor shaft direction, and an input-output terminal of the resolver is electrically connected to the control substrate.
