Abstract

The improvements of the new structure of a brushless DC (BLDC) motor with the low cogging torque for the ceiling fan is presented. The new type ceiling fan is designed by using BLDC motor theory and the six-step wave form for the purpose of the manufacture cost reduction. The energy also can be saved at least 50% when the new type motor is compared to the conventional fan based on the induction motor. The cogging torque also can be improvement by using the sin back EMF voltage with the sine wave form currents. The new BLDC motor is required to meet both of the basic ceiling fan control and the cost reduction.
