Brushless motors are often used in model aircraft, drones, household appliances, medical equipment, power tools, water pumps, cooling fans and other industries, at present, it is still relatively hot, favored by the majority of friends, including the current new energy industry, but also a large number of brushless motors, so full of potential.
Speaking of brushless motor, I have to mention its core components stator and rotor, especially the stator part, stator winding is a more troublesome process, used to be commonly used manual or semi-automated to wind, now commonly used winding machine equipment, for brushless motors, the current market often has needle type inner winding machine and flying fork outer winding machine two kinds of equipment, both can give brushless motor stator winding, so what is the specific difference? To summarize the following points:
1. For different products, the needle type inner winding machine is mainly aimed at stator products with the groove inward; the flying fork outer winding machine is mainly aimed at the stator products with the groove outward.
2. Winding methods and principles are different, the inner winding machine adopts the upper hook line or the lower hook wire winding mode, through the servo drive control, the needle rod nozzle drives the enameled wire up and down, the mold rotates left and right, and the line is neatly wrapped into the groove; the flying fork winding machine mainly adopts the flying fork winding method, through the rapid rotation of the flying fork, driving the enameled wire to follow the movement, and under the interaction of the stator rod, stator skeleton, die, and guard plate, the line is neatly wrapped into the stator groove.
3. The winding speed is different, and the high-speed inner winding speed can reach 800-1000R.P.M; the high-speed outer winding speed can reach more than 2500R.P.M.
4. The machine configuration is different, the ordinary inner winding machine configuration is relatively high, often built with imported servo drive and high-precision guide rail, screw, cylinder, etc.; and the ordinary flying fork winding machine can be matched with stepper motor, can also be matched with servo motor, do not need precision wiring, the requirements are not high, can be configured simply, high requirements on the configuration of higher.
5. The price of the machine is different, in general, compared to the ordinary configuration, the price of the inner winding machine is higher, and the external winding machine is relatively economical.
The above is the difference between the needle inner winding machine and the flying fork outer winding machine, both have their own advantages and characteristics, according to their own products to choose a reasonable winding machine equipment, in order to save manpower for enterprises, improve production efficiency!
