Abstract: A motion control system that includes a support motion control system and a body motion control system. The body motion control system includes passive motion control components and active motion control components.

Abstract: The present invention relates to a multi-fan assembly with an oscillating structure comprising a base body, a mounting seat, a differential mechanism, an oscillating link system, and a down rod. When the differential mechanism rotates the oscillating system, the base body of the multi-fan assembly and the mounting seat will be caused to oscillate limitedly, so that the airflow rate can be effectively controlled through the self-rotation and the revolutionary oscillation of the member fans.

Abstract: A worm-gear type ceiling fan motor comprises a stator, a rotor, two bearings, two heat-expelling covers, the stator and the two bearings are fixed on a motor shaft, the rotor is fixed on the bearings by cooperating with the heat-expelling covers. A plurality of hollow slots are formed on surface of the heat-expelling covers, in which are provided with plural worm-gear blades, when the rotor rotates, fresh air is instantly introduced into the ceiling fan motor via the upper heat-expelling cover expelled out from the lower heat-expelling cover, thus, air is circulated through the inside of the worm-gear type ceiling fan motor to cool down the working temperature and prolong the service life of the ceiling fan motor accordingly.
