Composite electromagnetic material engine

Abstract

The invention relates to a compound electromagnetism material starter. The invention comprises a machine casing, a front end cover, a rear end cover, an electromagnet switch, a rotator assembly, a stator assembly, an output gear, a middle separating plate and a shifting fork, the technical main point is: aluminum electromagnet rotator coils are distributed in the iron core groove of the rotator of the rotator assembly, a wrapping type copper and aluminum compound dip welding structure is adopted at the connection between the outgoing line of the rotator coil and the commutator, a rolling bearing is arranged at the connection between the both ends of the rotator assembly axle and the front and rear end covers, and a bearing transverse orientation device is arranged at the inner side of the front end cover. Four groups of aluminum electromagnet coils are distributed at the inner side of the machine casing of the stator assembly, and overlapping type welding structure is adopted at the connected of the ends of the adjacent two groups of aluminum electromagnet coils. Because the wrapping type copper and aluminum compound dip welding structure is adopted at the above connection, in order to realize the copper and aluminum welding in the starter, and to enable the replacement of the copper wire by the aluminum electromagnet wire to be possible. The invention also has the advantages that the structure is simple and reasonable, the cost is inexpensive, the working performance is stable, and the service life is long, as well as the application scope is broad.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a composite electromagnetic material starter for agricultural motor vehicles. Background technique [0002] As we all know, the traditional starter motor structure is composed of: DC motor, electromagnetic switch, driving gear, etc., and the electromagnetic coil is all made of copper material. Because copper material has good conductivity, it is widely used, but In recent years, due to the continuous rise in the price of copper materials, product promotion has been affected to a certain extent. Aluminum has good electrical conductivity and excellent thermal conductivity, as well as low production costs, and can completely replace copper in this field. However, due to the difficulty of its welding technology and complicated process, it has not been popularized and applied in this field so far.

[0002] As we all know, the traditional starter motor structure is composed of: DC motor, electromagnetic switch, driving gear, etc., and the electromagnetic coil is all made of copper material. Because copper material has good conductivity, it is widely used, but In recent years, due to the continuous rise in the price of copper materials, product promotion has been affected to a certain extent

Aluminum has good electrical conductivity, excellent thermal conductivity, and low production cost, so it can completely replace copper in this field. However, due to the difficulty of welding technology and complicated process, it has not been popularized and applied in this field so far.
