Efficient generator with help of coil tap

Abstract

The invention discloses an efficient generator with the help of a coil tap. The efficient generator comprises a stator and a rotor, wherein a plurality of coil slots are uniformly distributed along the circumference of a stator core, and a three-phase coil winding is nested in each coil slot; each phase of the coil winding consists of at least four single-turn coils which are connected with each other end to end; each coil is provided with a head tap, a middle tap and a tail tap; the first coil to the fourth coil in an A phase coil winding are crossly wound on the first coil slot and the fourth coil slot, the ninth coil slot and the twelfth coil slot, the fourteenth coil slot and the seventeenth coil slot, and the nineteenth coil slot and the twenty-second coil slot in sequence; the eleventh coil to the fourth coil in a B phase coil winding are crossly wound on the second coil slot and the fifth coil slot, the seventh coil slot and the tenth coil slot, the fifteenth coil slot and the eighteenth coil slot, and the twentieth coil slot and the twenty-third coil slot in sequence; and the first coil to the fourth coil in a C phase coil winding are crossly wound on the third coil slot and the sixth coil slot, the eighth coil slot and the eleventh coil slot, the thirteenth coil slot and the sixteenth coil slot, and the twenty-first coil slot and the twenty-fourth coil slot in sequence. The generator in the invention has the advantages of small reluctance torque and high generation efficiency.

Description

technical field [0001] The invention relates to a generator, in particular to a high-efficiency generator by means of coil taps. Background technique [0002] As a power source, generators are widely used in various industries. However, the disadvantages of existing generators are large resistance torque and low power generation efficiency. Taking wind power generators or hydroelectric generators as an example, when coming When the flow velocity is small, due to the large resistance torque of the generator, it is difficult for the unit to enter the starting state, let alone output electric energy to the outside. That is to say, the wind energy and water energy in this case cannot be effectively converted into electric energy, thus cause a waste of energy. In order to maximize the use of wind or water energy, in addition to optimizing the hydrodynamic shape of the impeller of the wind turbine or hydroelectric generator to improve its energy absorption efficiency, it is also ...
