    摘要： A motor drive device employed, for example, in an electric power steering apparatus for vehicle, achieves a reduction not only in size but also in vibration and noise at the same time.At least one of a motor drive control unit (30) and a motor (10) is provided with at least two screw holes (53) for fixation to a gear (speed reducer) of an electric power steering apparatus. Let L1 be a maximum value of a distance between center points of the screw holes (53) and L2 be a distance between an end face (D) of a stator iron core (12) in an axial direction on a farther side from the gear and an attachment surface (C) attached to a gear side, then a value of L1 is equal to or greater than a value of L2.

    摘要： The axial direction of a worm wheel is defined as a motor short-transverse direction, and a plane orthogonal to the motor short-transverse direction is defined as a motor flat plane. An imaginary plane contacting a first end of a sensor magnet in a motor short-transverse direction and parallel with the flat plane is defined as a first imaginary plane. An imaginary plane contacting a second end of the sensor magnet in the motor short-transverse direction and parallel with the flat plane is defined as a second imaginary plane. A control circuit board is provided with a rotation detecting element that detects rotation of the rotary shaft of the motor. The control circuit board is arranged to be parallel with or inclined relative to the flat plane, and is provided between the first and second imaginary planes.
