ABSTRACT:
A single bearing motor comprises a fan blade set, a motor set and a fan blade base. The fan blade set has a fan blade hub to join with a spindle fitting with a bearing on the outside thereof. The motor set is attached to the fan blade base and a hollow axial seat is provided in the center of the fan blade base to receive the bearing. Further, magnetic elements are disposed at the axial seat to avoid internal clearances being created for lack of a preset pressure acting on the bearing casing and balls therein. The balls and the bearing itself can run smoothly to effectively enhance motor operation.
