Stator for birotor generator and manufacturing process of stator

Abstract

The invention relates to a stator for a birotor generator. The comprises a plurality of iron core units which are annularly arranged;excitation coils are wound on the iron core units; supporting plates are inserted between the intervals of the iron core units; the top ends of the supporting plates abut against the inner wall of a shell; the excitation coils are fixedly connected with the iron core units and the supporting plates. The invention relates to a manufacturing process for the stator of the birotor generator. The manufacturing process comprises the following steps of: 1, inserting and fixing iron core units in notches of a support frame; 2, winding excitation coils on the iron core units; 3, inserting supporting plates into the gaps of the iron core units; 4, fixedly connecting the iron core units, the excitation coils and the supporting plates; 5, taking out the support frame; 6, winding the residual excitation coils; and 7, fixedly connecting the excitation coils with the iron core units. According to the stator and the manufacturing process thereof, higher magnetic flux density can be generated, the power generation efficiency of a generator is improved, and the stability of the stator structure is ensured.

Description

technical field [0001] The invention relates to the field of generators, in particular to a stator for a dual-rotor generator and a manufacturing process thereof. Background technique [0002] The generator is based on the law of electromagnetic induction and the law of electromagnetic force. The general principle of its construction is to use appropriate magnetic and conductive materials to form a magnetic circuit and circuit for mutual electromagnetic induction to generate electromagnetic power and achieve the purpose of energy conversion. Due to the inevitable existence of various forms of energy loss in the process of energy conversion, resulting in the reduction of energy conversion efficiency, how to minimize energy loss to improve energy conversion efficiency is an important issue that technicians in the field of generators continue to explore. . [0003] A conventional generator generally includes a housing 3, a stator, a rotor 4, a rotor shaft 1, and an excitation ...
