ISG (Integrated Starter Generator) driven motor coil

Abstract

The invention discloses an ISG (Integrated Starter Generator) driven motor coil which comprises a plurality of coil elements (1), wherein each of the coil elements (1) is a hollow cylinder which is formed by winding and stacking a complete wire in a rectangular shape along longitudinal direction. An end point of one coil element (1) is connected with a starting point of an adjacent coil element (1). Compared with the traditional motor coil, the ISG driven motor coil has the advantages that: the end height of the coil is reduced and the axial length of a winding iron core of the motor is effectively controlled, so that the structure of the motor is more compact; and the coil elements are directly connected, so that the connecting length of the adjacent coils is reduced and the cost is lowered.

Description

technical field [0001] The invention relates to a coil, in particular to an ISG drive motor coil. Background technique [0002] The AC drive system is widely used in electric vehicles due to its advantages of high efficiency, high energy density, large driving force, reliable operation and almost no maintenance. [0003] ISG drive motor is also widely used in electric vehicles as a kind of AC drive system. The ISG drive motor is directly integrated on the engine shaft to reduce engine idling loss and pollution. It is an energy-saving and environmental protection solution between hybrid and traditional vehicles. However, due to the short axial dimension of the ISG drive motor, the requirements for the size of the end of the motor coil are extremely strict. like figure 1 and figure 2 As shown, the end of the traditional motor coil A2 is arc-shaped, and the end of the traditional motor coil B3 is triangular. It is difficult to meet the requirements for the size of the end ...

AI Technical Summary

Problems solved by technology

However, due to the short axial dimension of the ISG drive motor, the requirements for the size of the end of the motor coil are extremely strict.

like figure 1 and figure 2 As shown, the end of the traditional motor coil A2 is arc-shaped, and the end of the traditional motor coil B3 is triangular. It is difficult to meet the requirements for the size of the end of the ISG drive motor coil, which makes the manufacture of the ISG drive motor difficult and expensive.
