Embodiment Construction

[0020] A generator stator winding, comprising a silicon steel sheet 1, a plurality of inner slot teeth 3 and a plurality of outer slot teeth 4 on the silicon steel sheet 1, the positions of the plurality of inner slot teeth 3 and the plurality of outer slot teeth 4 in the radial direction Correspondingly, the gaps between the plurality of inner teeth 3 form the inner groove 2 facing the direction of the center of the circle, and the gaps between the plurality of outer teeth 4 form the outer groove 5 away from the direction of the center. Multiple silicon steel sheets 1 of the same structure are stacked together to form the stator of the generator.

[0021] A method for winding a stator winding of a generator, specifically comprising the following process:

[0022] In the card slot of each silicon steel sheet, take the ring part of the silicon steel sheet group as the axis, and wind it into a ring coil according to the specified direction. In the slot, the number of turns ...

Abstract

The invention discloses a generator stator winding and a winding method of the generator stator winding. The novel generator stator winding comprises a plurality of silicon steel plates, wherein a plurality of inner slot teeth and a plurality of outer slot teeth are formed on each silicon steel plate; the plurality of the inner slot teeth and the plurality of the outer slot teeth are in positional correspondence in the radial direction; inner blocking slots facing towards the direction of the center of the circle are formed in the gaps among the plurality of the inner slot teeth; outer blocking slots deviating from the direction of the center of the circle are formed in the gaps among the plurality of the outer slot teeth; and the plurality of the silicon steel plates of the same structure are overlapped together to form the stator of the generator. According to the winding method of the generator stator winding disclosed by the invention, the variation magnetic fields in the silicon steel plates are sufficiently utilized to generate induced current, so that the intensity of the generated current is directly improved on the condition of not verifying the input power; and the generating efficiency of the generator is improved on the condition of not increasing the input mechanical energy.

Description

[0001] technical field [0002] The invention relates to a generator stator winding and a winding method thereof. Background technique [0003] At present, in all kinds of generators seen, the stator windings are composed of silicon steel sheets with slots in the inner ring and enameled wires (or copper bars), and the enameled wires are stuck in the slots of the silicon steel sheets according to the specified rules. Their common feature is that the effective power generation parts of the enameled wire are all stuck in the groove of the silicon steel sheet facing the center of the circle. This stator winding method keeps the wires parallel to the magnetic rotor, allowing the wires to "cut the flux lines" to generate electricity. At the same time, silicon steel sheet, a highly magnetic material, plays a vital role in improving the generator's power generation efficiency. If there is no silicon steel sheet as a support for the enameled wire, and a non-magnetic material is used...
