Fit structure.
On the basis of such scheme, the quantity of the fit structure is equal to the quantity in the space.
On the basis of such scheme, the thickness of the fit structure is less than the thickness of magnet steel 2.
On the basis of such scheme, the magnet steel 2 is arranged on the outer wall of punching 4 by bonding method.
On the basis of such scheme, the generator amature is quadrupole.
On the basis of such scheme, the magnet steel 2 is shaped as ring-type prismatoid, the fit structure be shaped as with
The ring-type trapezoid cylinder that the space matches.
On the basis of such scheme, the length of the magnet steel 2 is 80mm, and outer annular diameter is 70mm, and annular diameters are
62mm；A diameter of 10mm at a diameter of 62mm of the punching 4, front and rear shaft；The outer annular diameter of the base of the fixed cover 1 is
68mm, the annular diameters of base are 10mm, and the thickness of base is 5mm；The annular diameters of the ring-type trapezoid cylinder are 62mm, ring
A height of 40mm of shape trapezoid cylinder.
The magnet steel 2 fixed by fixed cover 1 is because rim pressure makes magnet steel 2 be difficult to drop, therefore magnet steel 2 is by radial load
When, the magnet steel 2 on rotor will not fall off.And because the permeability of fixed cover 1 is close to air permeability, to magnetic Circuit Design
Very little is influenceed, leakage field is reduced, so generator performance is barely affected.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Figure 1-3, a kind of generator amature, including：Fixed cover 1, magnet steel 2, punching 4 and rotating shaft 3；The magnet steel 2
The outer wall of punching 4 is arranged on, the punching 4 is arranged in rotating shaft 3, it is characterised in that：The fixed cover 1 can be from punching 4
The space that two ends are inserted between adjacent magnet steel 2 respectively axially back and forth, and with the fit structure for preventing that magnet steel 2 from coming off, it is described to match somebody with somebody
The space closed between the shape and adjacent magnet steel 2 of structure matches.
On the basis of such scheme, the permeability of the fixed cover 1 is close to the permeability of air, and hardness is 105-
175HV。
On the basis of such scheme, the permeability of the fixed cover 1 is 0.99990.
On the basis of such scheme, the fixed cover 1 includes annular base and some is arranged on the annular base
Fit structure.
On the basis of such scheme, the quantity of the fit structure is equal to the quantity in the space.
On the basis of such scheme, the thickness of the fit structure is less than the thickness of magnet steel 2.
On the basis of such scheme, the magnet steel 2 is arranged on the outer wall of punching 4 by bonding method.
On the basis of such scheme, the generator amature is quadrupole.
On the basis of such scheme, the magnet steel 2 is shaped as ring-type prismatoid, the fit structure be shaped as with
The ring-type trapezoid cylinder that the space matches.
On the basis of such scheme, the length of the magnet steel 2 is 80mm, and outer annular diameter is 70mm, and annular diameters are
62mm；A diameter of 10mm at a diameter of 62mm of the punching 4, front and rear shaft；The outer annular diameter of the base of the fixed cover 1 is
68mm, the annular diameters of base are 10mm, and the thickness of base is 5mm；The annular diameters of the ring-type trapezoid cylinder are 62mm, ring
A height of 40mm of shape trapezoid cylinder.
