Example Embodiment

[0014] Such as figure 1 , figure 2 The engine rotor shown includes a main shaft 1, a rotor core 2 and a coil 3; the rotor core is installed on the main shaft with evenly distributed slots on its outer circumferential surface; the coil is embedded in the slot of the rotor core, and the coil The end has a joint and is wrapped with an insulating film or wool tape; the two ends of the rotor core are covered with an insulating hoop 4 slightly larger than the outer circle of the coil end, and a coil is formed between the rotor core and the insulating hoop At the end, the insulating hoop is a steel hoop and a multi-layer high temperature insulating film is wrapped on the steel hoop. Of course, it can also be other components; the insulating hoop is wrapped with a high temperature resistant insulating layer, the high temperature resistant insulating layer is high temperature resistant The insulating film layer or wool weft tape, obviously, can also be other high temperature resistant ins...

Abstract

An engine rotor includes a principal shaft, a rotor core, a coil and an insulating bracket cover; the rotor iron is mounted on the principal shaft, and is provided with a groove on the outer circumference surface; the coil is arranged in the groove of the rotor core; the insulating bracket cover is covered on two ends of the rotor core, and the insulating bracket cover is coated with high temperature resistant insulation layer outside. A method for manufacturing the same includes the steps of mounting the rotor core on the principal shaft firstly, then embedding the coil into the groove of the rotor core and linking the coil joints, banding the joints with insulating tapes well, casing the insulating bracket cover on the rotor core end section, and then coating the high temperature resistant insulation layer outside the insulating bracket cover, finally making the bracket cover and the coil end section to form one body by means of dipping paint and high-temperature bake. The structure of the invention intensify greatly the mechanical strength of the rotor coil end section, and the coil end section is not easy to disassemble to throw out the core groove, which ensures non friction between the rotor and the stator, and ensure the generator from being burned.

Description

technical field [0001] The invention relates to a generator rotor and a manufacturing method thereof. Background technique [0002] The current generator rotor is composed of a main shaft, a rotor core and a formed or wound coil. The rotor core is mounted on the main shaft, and the outer surface of its circumference has evenly distributed grooves, and the coils are embedded in the iron core slots. , and then weld or form the end of the coil, and then bind the end with wool weft tape, and strengthen the strength of the rotor coil after dipping paint and baking at high temperature. With this structure, when the high-power load of the generator is suddenly increased or decreased, or the welding of the formed coil end is bad, resulting in high temperature, or the mechanical strength of the scattered coil end is insufficient, the wool weft belt at the end of the rotor will lose its function, resulting in the overall coil end. The part disintegrates, so that the coil is thrown ou...
