    摘要： A material of the stator core is different from a material of the housings, in a state where one end portion in the axis direction of the stator core is contacted to the first housing, and the other end portion in the axis direction of the stator core is contacted to the second housing; and a neighboring portion of a contact portion, at which the first housing is contacted to the stator core, and another neighboring portion of a contact portion, at which the second housing is contacted to the stator core, are connected by a connecting component in the axis direction, of which material is the same as a material of the stator core, whereby the first housing and the second housing are connected each other; and the first housing and the second housing face each other in a state where a gap intervenes between both housings.

    摘要： A permanent magnet rotating electric machine includes: a stator including: a stator core having teeth, and an armature winding wound around each of the teeth to configure the multiple phases; and a rotor including a rotor core, and permanent magnets provided in order around the rotor core. The rotor is arranged to be spaced apart from the stator with an air gap therebetween. Each of the permanent magnets has a curved surface opposed to the stator and is configured to satisfy the following relationship: 0.65 ≤ Rm × h ⁢ ⁢ 1 W ⁡ ( h ⁢ ⁢ 1 + g ) ≤ 1.37 where Rm denotes a radius of curvature of the curved surface, h1 denotes a thickness of a central portion of the permanent magnet in the peripheral direction, W denotes a width of the permanent magnet in the peripheral direction, and g denotes an air gap length of the air gap.

    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.
