Problems solved by technology

Using the above-mentioned existing technology, the action of wrapping the metal strip is relatively complicated, which is labor-intensive and limits the improvement of production efficiency
At the same time, if the traditional wrapping method is used to place insulating material outside the metal strip, the insulating material is difficult to be tightly combined with the metal strip and is easy to loosen
Especially in order to fix the metal strip, the width of the wire groove is closer to the width of the metal strip, and the gap between the wire groove and the metal strip is small. The action of wrapping the insulating material outside the metal strip and then inserting the wire groove will easily damage the insulation layer, Wrinkles will affect the insulation effect and limit the popularization and application of the above-mentioned motors

Abstract

The present invention provides a slot insulation method for a flat-wire motor stator. Stator wire slots are provided in the flat-wire motor stator; an insulation tube is provided in each stator wire slot; the insulation tube is an integrally formed insulation tube; the insulation tube is symmetrically inserted into the stator wire slot. According to the present invention, slot insulation is implemented by inserting an insulation tube into each stator wire slot of the flat-wire motor stator, and thus, production efficiency is high, product quality is stable, and insulation performance is good.

Description

technical field [0001] The invention belongs to the technical field of drive motors for electric vehicles, and in particular relates to a slot insulation method for flat wire motor stators. Background technique [0002] Electric vehicle drive motors (including permanent magnet brushless DC motors and AC induction motors) are new integrated motors that have emerged with the development of semiconductor electronics technology. It is the product of the combination of electronic technology, control theory and motor technology. It has high efficiency High, long life, no maintenance, etc., especially suitable for the engine of electric vehicles. [0003] There is an existing drive motor for electric vehicles, the stator of which includes a ring-shaped iron core, the inner wall of the iron core is provided with wire slots, and enameled wires are wound in the wire slots as windings. However, the strength of the magnetic field generated by the above-mentioned windings is low, which ...
