Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, but does not constitute any limit to the present invention
System, the amendment of anyone limited number of time made in scope of the invention as claimed, still the right in the present invention is wanted
In the range of asking.
The specific embodiment of the present invention is such that shown in reference Fig. 1, a kind of novel generator amature,
Including rotating shaft 1, collector ring 2, the 4, second pawl pole 5, collector-ring lead the 3, first pawl pole, Exciting Windings for Transverse Differential Protection 6,
Rotating shaft 1 passes from the center of the first pawl pole 4 and the second pawl pole 5, and Exciting Windings for Transverse Differential Protection 6 is arranged on the first pawl pole 4
And between the second pawl pole 5, Exciting Windings for Transverse Differential Protection 6 is connected with Exciting Windings for Transverse Differential Protection 6 by collector-ring lead, it is being positioned at the
Fore bearing supporting part, belt pulley installation portion outwards it is sequentially provided with from its root in rotating shaft 1 outside two pawl poles 5,
Rear bearing supporting part, installation outwards it is sequentially provided with from its root being positioned in the rotating shaft 1 outside the first pawl pole 4
The collector ring installation portion of collector ring 2, the rear bearing supporting part of rotating shaft 1 is provided with installs collector-ring lead 3
Axial notch 12, axial notch 12 is provided with the tabletting 11 of fixing collector-ring lead 3.Fore bearing supporting part
Being arranged on rotating shaft 1 root of both sides, pawl pole with rear bearing supporting part, the distance between two supporting-points contracts significantly
Little, when electromotor bears bigger power, can operate steadily, reduce fan blade abrasion, bearing damage several
