Background technology
At present, known brushless AC generator structure mainly contains three kinds: one, be pressed into stator core in the cast iron casing; Two, welded and installed muscle in the steel plate welding frame is pressed into the support inner chamber with stator core; Three,, the sheet metal casing is installed on the support stick, forms complete casing at stator core outside weldings support stick.There is following defective in these three kinds of structures: 1, processing technology is complicated, manufacturing cost is higher; 2, assembling process is more loaded down with trivial details, production efficiency is lower; 3, in the assembling process concentricity not high, be easy to generate the rotor friction and cause generator to damage.
Summary of the invention
The utility model provides a kind of cost brushless AC generator structure low, simple in structure to the deficiency of above-mentioned prior art, this electric generator structure concentricity with rotor of can enhancing productivity.
The technical scheme that provides according to the utility model: a kind of brushless AC generator structure; Comprise support and stator; Said support comprises the stack shell and the one-body molded expansion segment at said stack shell two ends of welding fabrication; The outer rim of said stator is one-body molded to have a plurality of convexities that are uniformly distributed with, and said convexity contacts with the inner chamber of said stack shell, forms heat dissipation channel between each said convexity.
The expansion segment at said stack shell two ends is by the die drawn moulding.
Be welded with axial connecting bolt seat in the said expansion segment.
The top of said stack shell is welded with hanger, and its underpart is welded with bearing.
Compared with present technology the utility model has the following advantages: the stack shell of generator pit and the expansion segment at two ends are one-body molded, simplified processing technology, reduced manufacturing cost; Stator is protruding directly to be contacted with the support inner chamber, and the installation muscle and the heat dissipation channel of formation nature between the convexity have been simplified connecting between stator and the support; Excitation system and transition connector directly are installed to the expansion segment at support two ends, have guaranteed the concentricity of rotor, have improved the quality of product percent of pass and finished product.
