Specific embodiment
Referring to Figures 1 and 2, a kind of rotor comprising frame shell 1, the shading ring 2 being set on frame shell 1 and be located at
The magnetic shoe 3 of 2 inside of shading ring.The side of frame shell 1 has boss 11, and the top of boss 11 is provided with the first threaded hole 12, boss
11 bottom is provided with the second threaded hole 13.
Shading ring 2 is partly or entirely made of metal material, and to armoured magnetic field, magnetic field is avoided to leak, and frame shell 1 is used for
Shading ring 2 and magnetic shoe 3 are installed, so that rotor becomes an independent component.
First threaded hole 12 is longitudinally-aligned with the second threaded hole 13 and is connected to, in order to the first threaded hole 12 and the second screw thread
The processing in hole 13.
In certain embodiments, bolster stake 14, the first threaded hole 12 and the setting of the second threaded hole 13 are provided on boss 11
In on bolster stake 14.Frame shell 1 generallys use the materials such as plastic cement and is made, and bolster stake 14 is then larger using metal material or intensity
Nonmetallic materials be made, thus can avoid the first threaded hole 12 and the second threaded hole 13 in helicitic texture be damaged.Phase
It answers, the bolster stake 14 of metal material is located at the outside of shading ring 2, in order to avoid interference magnetic field.
The side wall of boss 11 is connected with the side wall of frame shell 1 by cambered surface, to reduce structural stress, and can avoid frame shell 1
There are sharp corner angle between shell 5.
Frame shell 1 extends along magnetic shoe 3 is respectively formed limit layer with the top and bottom in magnetic shoe 3, passes through frame shell 1 and shielding
The collective effect of ring 2 can protect magnetic shoe 3, and magnetic shoe 3 is avoided to be damaged in the handling process, also can avoid in ceiling-fan motor
There is a situation where 3 avalanches of magnetic shoe to splash in operational process.
Referring to Fig. 3, the quantity of magnetic shoe 3 is several, several magnetic shoe 3 is sequentially arranged to surround a ring, adjacent magnetic
There is spacing between watts 3.
In the present invention, the thickness of magnetic shoe 3 is set as being gradually increased from two sides to centre.
Specifically, in certain embodiments, the lateral wall of magnetic shoe 3 is in the arc surfaced of evagination, the inner sidewall of magnetic shoe 3 is in plane
Shape.
