Abstract
The invention relates to a motor lubricant cycling system, wherein a plurality of slots are disposed in the inner wall of the shaft tube in contact with the bearing, one end of the slot is connected to the conjunction of the top side of the bearing and the shaft, the lubricant, due to the pump effect, elevates along the shaft when the motor is rotating at high speed and is sucked in the slot by a backflow suction, and the other end of the slot is connected to the lubricant container beneath the bearing in formation of a guiding path dedicated to the lubricant cycling. According, the lubricant can be recycled for operation so as to reduce the noise resulting from the motor operation and prolong the life cycle.
