Patent ID: 7705505

Claim:
A motor comprising: a shaft; a rotor magnet rotating along with the shaft centering around a central axis; a stator arranged radially opposite from the rotor magnet; a substantially cylindrical housing arranged to retain the stator, and including an opening portion at an axially upper side; a bracket arranged to cover the opening portion of the housing; a plurality of bearing portions supporting the rotor magnet with respect to the stator; and a resolver arranged to detect a rotational position of the rotor magnet, the resolver including: a resolver rotor affixed to the shaft; and a resolver stator including an annular portion arranged coaxially with the central axis and radially opposite from the resolver rotor, and a connector portion extending from the annular portion in a radially outward direction; wherein the bracket has a substantially cylindrical portion extending in an axially downward direction, and the substantially cylindrical portion includes a retaining mechanism arranged to retain the resolver stator, and the retaining mechanism includes a first positioner portion, and a second positioner portion arranged axially below the first positioner portion, the first positioner portion is arranged to contact with a top surface of the resolver stator, the second positioner portion is defined by a deformed portion of a bottom end portion of the substantially cylindrical portion that is deformed in a radially inward direction, and the resolver stator is sandwiched between the first positioner portion and the second positioner portion.
