What winding method is used for brushless outer rotor stator coil? How do you achieve precision lining?

There are many brushless outer rotors, like brushless model motors, cooling fans, drones, planters, twister, electric cars, etc. Many friends are more interested in coils, feeling a circle of winding up is fun, in fact, most of these coils are machine-wound, so what winding method is used for brushless outer rotors? Vacuz gives you an introduction to it!

Brushless outer rotor, which is actually a lot of friends commonly called, the correct term should be called the stator, because the coil is not moving, the outside shell plus the magnet is the rotor.

As the slot opening direction is facing outward, so generally use the external winding machine to solve the winding problem, which we often say flying fork winding machine, flying fork winding way is relatively simple, is also more common winding way.

Flying fork winding machine winding principle.

Mainly through the die head forward movement, die shedding top to the stator slot, die shedding can move back and forth, the stator by the stator rod positioning, fixed, then flying fork high-speed rotation, die head and stator rod in the role of the guard plate auxiliary, die shedding back and forth movement, enameled wire through the guard plate slide into the stator slot, regular winding in the stator slot, equipment power drive is generally stepper or servo motor, enameled wire export more with ceramic or tungsten steel wire Nozzle.

Ordinary flying fork winding machine generally for the precision of the coil is not much requirement, if you want a not chaotic to achieve precision line, you need to change the configuration, such as the configuration of imported servo motors and electric drive, so that the precision can be controlled higher, of course, the commissioning staff is also very important, including the line system, mold precision, etc., have certain requirements.

What winding method is used for brushless outer rotor? How to achieve precision lining? After reading the above, I believe you have a preliminary understanding, I hope you choose the flying fork winding machine, to understand more, more comparison, a good flying fork winding machine, in order to let you get twice the result with half the effort.
