In the outer rotor brushless DC motor, the outer rotating part is the rotor, and the inner fixed coil winding part is the stator. After the power is turned on, the two interact to make the motor run, so how is the stator winding of the outer rotor brushless DC motor wound? of? What kind of winding method is used? Let Vacuz analyze it for everyone!

For the outer rotor brushless DC motor, the slot of the stator core is generally outward, and the stator can be insulated by coating or by inserting paper, but the coating method is generally used, and the green paint is used.

As the outer rotor brushless DC motor has the notch facing outward, the flying fork winding machine is often used to solve the winding problem. Of course, the needle type inner winding machine can also be used, but it is not cost-effective, and the speed efficiency is not high. The speed of the flying fork winding machine It can reach more than 5000RPM, and it can be applied to large-volume stator winding.

The working principle is that the enameled wire is carried by the flying fork wire mouth, the die head part moves forward, fixes the position, clamps the slot of the stator with the die tongue, then the die tongue continues to move forward to the starting point of winding, and then starts to move backward, while flying The fork rotates at high speed, and the enameled wire slides into the slot of the stator through the action of the guard plate, and then reciprocates when there are multiple layers, until the coil of one slot is wound, and then the stator rod rotates to the next slot, and continues to do the previous action. After completing the winding work, the whole process is automatically wound, automatically arranged, automatically indexed, and automatically clamped and cut.

For each external winding product, the general winding requirements are different, some only need ordinary wiring, and some require precision wiring, so the configuration of the machine and the design of the winding are different. Yes, how to choose the correct flying fork winding machine equipment depends on your own needs. Only by choosing the appropriate winding machine equipment can you achieve twice the result with half the effort!
