Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing 1,2,3, the present invention is made further detailed
It states, the embodiment is only for explaining the present invention, is not intended to limit the scope of the present invention..
Be superimposed rotor brushless energy-saving motor outside a kind of permanent magnetism, including p-m rotor body (1), main shaft (2), stator body (6),
Outer housing (3), the first shell end cap (4), second housing end cap (5) composition, p-m rotor body (1) are affixed to main shaft (2)
Cylindhca permanent magnet and magnetic pole are magnet radial poles；Stator body (6) is cylindric iron core, and inner surface is evenly equipped with the first stator core
