The stator has a housing with n side portions and n connecting portions distributed alternately, wherein n is a integer equal to or greater than 3. Adjacent side portions are interconnected by one of the connecting portions. The radial cross section of each side portion is a convex curved line which is curved outwardly relative to a straight line passing through the two ends of the convex curve line. Permanent magnets are fixed to an inner surface of the housing. An end cap fixed to one end of the housing, has a bottom and n side walls extending from the bottom. A flat mounting surface is formed at the outer surface of a first one of the side walls.

摘要： A motor comprises a stator and a rotor (20) disposed within the stator. The stator comprises a shell comprising a plurality of sidewalls (10a-10d) and arcuate connection parts (11a-11d) connecting neighboring sidewalls. The cross section of the shell is a polygon with fillets. The stator also comprises a plurality of magnets (12a-12d) installed inside the arcuate connection parts. The magnets (12a-12d) are mutual arranged at intervals. The outer surface of each magnet (12a-12d) is attached to inner surfaces of the two neighboring sidewalls (10a-10b) and a gap is formed between the magnet and the inner surface of the corresponding arcuate connection part. Air gaps are formed between the inner surface of the magnets (12a-12d) and the outer surface of the rotor. Disposing the magnets inside the arcuate connection parts improves the space utilization ratio. In addition, the gaps formed between the outer surface of magnets and the inner surface of arcuate connection parts may be used for adhesive to fix the magnets to the shell.
