Non-joint wire embedding device for random-embedded windings of large-power motor stator and wiring method

Abstract

The invention discloses a non-joint wire embedding device for random-embedded windings of a large-power motor stator. The non-joint wire embedding device comprises a base, wherein a supporting plate is rotationally connected to the base; at least three wire releasing frames are rotationally connected to the first supporting plate; a horizontal wire releasing rod is arranged on each wire releasing frame and passes through the wire releasing frame; the middle of each wire releasing rod is rotationally connected with the corresponding wire releasing frame; and fixing devices are arranged at two ends of each wire releasing rod. The invention further discloses a wiring method, which sequentially comprises the steps as follows: variable-frequency enameled circular electromagnetic wires are wound on circular wire discs; a stator iron core is vertically placed on a rolling frame; two wire releasing devices are respectively placed on two sides of the stator iron core; the wire discs are evenly placed on the wire releasing rods of the wire releasing devices on the two sides of the stator iron core by phase number; the variable-frequency enameled circular electromagnetic wires are embedded into the stator iron core; and after the wires are embedded into the stator iron core, the end parts of coils are manually bent. The non-joint wire embedding device and the wiring method have the advantages that the wires are continuously and randomly embedded into the stator iron core, the insulating integrity of the windings is guaranteed, materials and production costs are saved, and the performance of the motor is improved.

Description

technical field [0001] The invention relates to a nodeless wire embedding device and a wiring method of a large-power motor stator scattered embedding winding. Background technique [0002] Existing stators of high-power motors, such as wind power generators, all use a single flat wire to form a coil. Due to the immature domestic frequency conversion flat magnet wire technology, in order to achieve the ideal anti-corona effect according to the special requirements of wind turbines, it must rely on the follow-up insulation system to ensure that the cost is high and the technology is difficult. The stator coil adopts flat wire. A system of processes such as winding, drawing, shaping, insulation, hot pressing, and welding must be carried out first, which has a long production cycle, high cost, and high technical difficulty. Contents of the invention [0003] The object of the present invention is to provide a nodeless wire embedding device and a wiring method for a stator lo...
