Problems solved by technology

[0003] Since the flat copper enameled wire stator assembly needs to insert 192 formed enameled wires in a small space and weld 192 solder joints, the process is very difficult. Special equipment is required for forming, interspersing, twisting and welding enameled wires , the investment is very large, the production efficiency and yield are very low, and the Japanese factory has patent protection, if it is not authorized, it cannot be mass-produced and sold

Abstract

The invention discloses a stator assembly of an alternating-current power generator of an automobile, and relates to high-capacity stator assemblies with output power of 14 volts times 120-150 amperes. The stator assembly comprises a stator iron core, stator coils, insulation slots and slot wedges. Round copper enameled wires are wound to form the stator coils, the stator coils are embedded in slots of the stator iron core and are cushioned by the insulation slots, the slot wedges are tightly inserted in notches of the stator iron core, and the stator coils are fixed into the slots of the stator iron core by the aid of the slot wedges. The stator assembly is characterized in that silicon steel sheets with the thicknesses of 0.35 millimeter are overlaid and welded with one another to form the stator iron core; the outer diameter of the stator iron core ranges from 128 millimeters to 129 millimeters, the inner diameter of the stator iron core ranges from 99.5 millimeters to 100.5 millimeters, the thickness of the stator iron core ranges from 32 millimeters to 33 millimeters, the stator iron core is provided with the 48 slots and 48 teeth, the diameter of the bottom of each slot of the stator iron core ranges from 120.2 millimeters to 121.2 millimeters, and the width of each tooth of the stator iron core ranges from 2.4 millimeters to 2.6 millimeters; the stator iron core is manufactured by the aid of a single-group or double-group independent three-phase delta connection method. The stator assembly has the advantages that the high-capacity stator assembly is made of the round copper enameled wires instead of the original flat copper enameled wires and is used on power generators of NIPPONDENSO series automobiles, a process is simplified, equipment is simple, and the cost is lowered.

Description

technical field [0001] The invention relates to the technical field of automobile generators, in particular to an automobile generator stator assembly. Background technique [0002] The existing new NIPPONDENSO (Japan Denso) series automotive generators use flat copper enameled wire high-capacity stator assembly. The output power of this stator assembly is about 30% higher than that of ordinary stators of the same volume. Insert it into the slot of the stator core, then twist the head, splice the wires, and weld, and insulate the slot between the stator core slot and the stator coil to prevent the coil from grounding. Each outlet of the stator coil is drawn from a specified angle for Output the current when the stator generates power. The stator core is 96 slots and 96 teeth. [0003] Since the flat copper enameled wire stator assembly needs to insert 192 formed enameled wires in a small space and weld 192 solder joints, the process is very difficult, and special equipmen...
