Winding, stator and motor

Abstract

The invention relates to a winding, a stator and a motor. The winding comprises: a plurality of coils; each coil comprises a double-layer conductor module, a first conductor and a connecting conductormodule; the double-layer conductor module is connected with the first conductor through the connecting conductor module; the double-layer conductor module comprises a second conductor and a third conductor; and the connection conductor module comprises a first connection conductor and a second connection conductor. The second conductor and the third conductor are vertically arranged side by side,the output end of the second conductor is connected with the input end of the first conductor through the first connecting conductor, and the output end of the first conductor is connected with the input end of the third conductor through the second connecting conductor. According to the invention, the second conductor and the third conductor are arranged side by side up and down, so that the twoconductors have a capacitance effect under high-frequency pulse potential excitation, the loss is reduced when current flows through the conductors, the electrical load density of the motor can be improved, and the high density of the motor is realized.

Description

technical field [0001] The invention relates to the field of motors, in particular to a winding, a stator and a motor. Background technique [0002] In the industrial field, 60% of the electric energy is used by the motor. In some occasions that require the installation space of the motor, such as the electric drive of the vehicle, the high efficiency and high density index of the motor system has become an important direction of technological development. The high efficiency of the motor is high. Densification is the development goal of the motor industry. It can not only improve the energy efficiency of the system, but also greatly reduce the cost of materials and realize miniaturization. It has obvious practical value in many occasions (such as electric vehicles, aerospace, military industry, etc.). The coil in an ordinary AC motor has an integer number of turns, and the number of turns is generally more than 2 turns. The coil of a conventional AC motor exceeds two turns ...

AI Technical Summary

Problems solved by technology

The coil in an ordinary AC motor is an integer number of turns, and the number of turns is generally more than 2 turns. The coil of a conventional AC motor exceeds two turns (more than two turns). During the transmission of electromagnetic energy, part of the electromagnetic energy enters the conductor and is converted into conduction loss. Reduce the efficiency and density of the motor. In order to solve the above problems, the 2025 technology route of electric vehicles in the United States lists the super wire based on graphene and copper materials as the research and development goal. In 2015, the Oak Ridge National A breakthrough has been made in the preparation method of graphene, which solves the problem of graphene accumulation and greatly promotes the super wire project. However, at present, this technology is still in the laboratory stage, the cost is high, and there is a long distance from practical application, so it is urgently needed A motor with high efficiency and high density
