ABSTRACT:
The invention relates to a motor's stator for a household fan whose silicon steel sheets have an enlarged middle hole for increasing from 16 slots to 24 slots along the circumference of the middle hole. Accordingly, the number of poles is increased from four to six so as to form a six-pole motor that upgrades the revolutions and torsion. In addition, the enlargement of the middle hole can correspondingly diminish the whole area of the slots so that the number of turns in the slots can be lowered. Meanwhile, the material cost is reducible, the temperature rise is suppressible and the efficiency is enhancable.
