ABSTRACT:
A motor with single bearing 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. The motor set is attached to the fan blade base and a hollow axial seat is provided in the fan blade base to receive the bearing. Further, an elastic element or magnetic element is disposed at the axial seat to avoid internal clearance being created by lacking preset pressure acing to the bearing casing and balls therein. The balls and the bearing itself can run successfully to enhance operation of the motor effectively.
