Patent ID: 8587172

Claim:
A sensor fastening frame for fastening in position a sensor to an axial side surface of a motor stator of a distributed-wound brushless DC motor, wherein the motor stator has a first coupling portion, the sensor fastening frame comprising: a wall-less flat plate extending toward a second direction; a second coupling portion directly provided to the plate and extending toward a first direction perpendicular to the second direction, further comprising a carrier board that is integral with a fastening pin; and a planar flat fastening part directly attached onto the plate and parallel to the plate, and disposed at a same level as the plate for directly securely fastening the sensor and extending toward the second direction, wherein the fastening pin of the second coupling portion is installed to said motor stator at a fixed angular location with the carrier board resting upon the axial side surface of the motor stator; and wherein the plate is formed with an adjustment slot, and the second coupling portion is formed with a sliding rail for being engaged with the adjustment slot via at least an adjustment screw, so as to secure the second coupling portion to the plate such that the relative angular location of the plate is adjustable with respect to the fixed angular location of the second coupling portion, and wherein the sliding rail is spaced apart from the carrier board a height sufficient to allow the planar flat fastening part to cross over windings of the motor stator.
