In one text of machine " (number of patent application: CN200920172777) patent, inventor is to permanent magnetism spherical motor rotor structure and rotor
Modes of emplacement has carried out to discuss detailed in stator, gives the detailed description of rotor magnet structure design, but not to fixed
Minor structure is specifically designed, and is also specifically discussed without detailed structure heat dissipation technology, is only simply secured to the coil of stator
It is simply introduced on shell, from its stator structure figure, it can be seen that, stator structure is just to describe structure herein above
Drawback, coil are only individually fixed on stator spherical shell, and radiating mode is natural heat dissipation, and heat dissipation effect is excessively poor, are being improved
It is also significantly limited in terms of power density.
