Magnetizing base tool, magnetizing base winding structure, magnetizing device and manufacturing method thereof

Abstract

The invention provides a magnetizing base tool, a magnetizing base winding structure, a magnetizing device and a magnetizing method thereof. The magnetizing base tool includes a shaft rod and a guide sheet arranged on the surface of the shaft rod around the axis of the shaft rod. By utilizing a magnetizing yoke sheet for cooperating with the guidance of the guide sheet of the magnetizing base tool, the magnetizing base winding structure provided with a plurality of pole arms can be manufactured quickly. Therefore, a problem that the pole arms are not easy to form through cutting caused by the micromation can be solved. And since the magnetizing base winding structure is formed by piling the magnetizing yoke sheets together, a contact area of the magnetizing yoke sheets and the magnetizing coil can be increased, the heat dissipation efficiency and magnetizing efficiency can be improved, and the service lifetime and the reliability of the magnetizing base winding structure can be improved at the same time.

Description

technical field [0001] The present invention relates to a jig, a manufacturing method of the applied jig, and a product made by the manufacturing method, in particular to a magnetizing seat jig, a magnetizing seat winding structure, a magnetizing device and a manufacturing method thereof. Background technique [0002] The motor includes a stator set on a circuit board, and a rotor driven by the stator. The rotor has a magnet ring with alternating N and S poles, and the stator has multiple sets of coils and stator teeth with fixed coil windings. Slot yoke, and electrified by Hall sensor to sense the polarity of the rotor magnet, so that the stator coil induces a rotating magnetic field to drive the rotor magnet to rotate. [0003] In terms of rotary motors, the N and S poles of the existing magnet rings are mostly radially arranged, and alternately arranged at intervals along the circumferential direction of the magnet rings, so that although it is easy to manufacture, as eve...

AI Technical Summary

Problems solved by technology

Using the inclined N and S poles can make the magnetic force distribution more even to overcome the cogging torque, but it is not easy to magnetize the inclined N and S poles of the magnetic field of the magnet ring. Generally, it needs to cooperate with figure 1 As shown, the magnetizing seat 1 formed with several inclined poles 11 made by cutting and forming can be magnetized to form N and S poles with inclined magnetic field

[0005] However, in recent years, the size of 3C products and household appliances has become smaller and smaller, which makes the size of the motor and the magnet ring of the rotor smaller and smaller, and the magnetizing base 1 needs to be smaller and smaller with the magnet ring. As a result, it is more and more difficult to cut and form the inclined pole 11 directly on the magnetizing base 1
