Shaft notch positioning device of pole coil

Abstract

The invention discloses a shaft notch positioning device of a pole coil. The shaft notch positioning device comprises a main pole coil inner ring sleeve and a main pole coil outer ring sleeve. The central axis of the main pole coil inner ring sleeve and the central axis of the main pole coil outer ring sleeve are located on the same vertical line. The main pole coil inner ring sleeve is positionedin the main pole coil outer ring sleeve; a connecting block is fixedly connected between the main pole coil inner ring sleeve and the main pole coil outer ring sleeve, a coil winding column is fixedly connected to the surface of the main pole coil outer ring sleeve, a guide limiting block is fixedly connected to the side, away from the main pole coil outer ring sleeve, of the coil winding column,and a wire passing pile is fixedly connected to the upper surface of the main pole coil outer ring sleeve. According to the shaft notch positioning device of the pole coil, the coil winding column and the winding clamping groove are arranged, the coil can be conveniently and regularly wound in the winding clamping groove so that the shaft notch positioning device of the pole coil can arrange thecoil orderly and consistently, the phenomena that the size of the coil is ultra-short and the turn is short are avoided and the purpose of reducing coil scrap is achieved.

Description

technical field [0001] The invention relates to the technical field of main pole coil positioning, in particular to a pole coil shaft notch positioning device. Background technique [0002] A coil usually refers to a ring-shaped wire winding. The most common coil applications are: motors, inductors, transformers, and loop antennas. A coil in a circuit is an inductor. It means that the wires are wound one by one, the wires are insulated from each other, and the insulating tube can be hollow, or it can contain iron core or magnetic powder core, referred to as inductance. Inductance can be divided into fixed inductance and variable inductance, fixed inductance coil is referred to as inductance or coil. [0003] The main pole coil is a very important part of a DC motor. The function of the main pole coil is to establish the main magnetic field through the DC current, and make the motor rotate by cutting the magnetic induction line. [0004] At present, in the manufacturing p...

AI Technical Summary

Problems solved by technology

[0004] At present, in the manufacturing process of the main pole coil, there are often phenomena such as coil wiring being messy and causing the coil size to be out of tolerance and the turns to be short. These two quality problems are often difficult to repair, and eventually lead to the scrapping of the coil.
