ABSTRACT:
A stator and rotor for a DC brushless ceiling fan motor includes an integrated design of the stator and rotor to form an integrated stator, the integrated stator is made of a permeable material and is formed by means of a secondary production process. The DC brushless ceiling fan motor further includes an electrical controlling circuit that comprises a computer microprocessor, a power supply, a frequency converter, a phase detector and a remote control device or a manual control switch with the purpose of controlling the speed and the orientation of the motor, and thus achieving the result of low working temperature and high electrical efficiency.
