Abstract
Motors for fans are provided. The motor includes a stator and a rotor. The stator includes a plurality of magnetic poles. The rotor is coupled to the stator and includes a magnetic structure with a plurality of magnetic poles. Each magnetic pole has an interpolar portion. A uniform gap is formed between the stator and the magnetic structure.
Claims19
A motor, comprising:
- a stator comprising a plurality of magnetic poles;
- a rotor coupled to the stator and comprising a magnetic structure comprising a plurality of magnetic regions, wherein each magnetic region comprises an interpolar portion for easily starting the motor;
- and
- a Hall sensor detecting the phase change of the magnetic poles, wherein the interpolar portion is located on a side of the magnetic structure corresponding to an induction surface opposite to the Hall sensor positioned on the other side of the magnetic structure, wherein a uniform gap is formed between the magnetic structure and the plurality of magnetic poles.
