What are the requirements for multi-wire parallel winding in the fully automatic stator winding mach

The stator windings are mostly produced by fully automatic winding equipment, which can be divided into inner winding machines and outer winding machines. Generally, single wire or multiple wires can be wound together. So, what are the requirements for multi-wire winding in fully automatic stator winding machines? What are the differences between inner winding and outer winding? Let NOYU introduce it simply to everyone below! 
 

Requirements for multi-wire parallel winding in the fully automatic stator winding machine: 
1. Requirements for stator slots: 
a. When multiple lines are wound together, since multiple strands are wound simultaneously, the wire diameter becomes thicker. Therefore, it is necessary to ensure that the distance between the stator slots is large enough to allow the multiple strands to pass smoothly through the slots, thereby reducing the risks of wire damage and breakage.
Stator height requirements: 
b. The higher the stator winding thickness, the greater the arc radius during winding, and the swing amplitude of the enameled wire also increases. When multiple wires are wound together, higher requirements are imposed on the stator height, and it is necessary to ensure the stability and safety of the wire during the winding process.
Wire diameter requirements: 
c. The requirements for slotting and winding speed vary depending on the different wire diameters. For instance, 4-wire parallel winding with a 0.3mm wire diameter is different from 4-wire parallel winding with a 0.5mm wire diameter. There are differences in winding speed and slot adaptability, and the winding parameters need to be adjusted according to the specific situation. 
2. Requirements for tensioners and auxiliary parts: 
a. When multiple lines are wound together, the stability of the line feeding is particularly important. Therefore, it is more common to use specialized servo tensioners for line feeding to ensure uniform and stable tension of the line material. At the same time, higher precision is required to guarantee the quality and stability of the winding process. 
3. Machine Configuration Requirements: 
b. During the winding process, the stability of the machine has a direct impact on the quality of the winding. Therefore, specialized servo motors, electric drives, lead screws, guide rails, cylinders, couplings, and other precision components need to be configured. Additionally, a stable and reliable frame structure and chassis are required to ensure the stability and accuracy of the winding process. 
4. Requirements for the machine debugging process: 
When multiple lines are wound together, the number of enameled wires increases, and the debugging difficulty also increases accordingly. Professional debugging technicians are required for installation and debugging to solve various possible wire damage and breakage problems, and to ensure the quality and stability of the winding. 
The difference between inner winding and outer winding 
Winding method: 
a. Inner stator winding: The slot opening direction is inward. It usually adopts the needle-type winding method. The winding process is completed by the movement of the needle rod up, down, left and right in coordination with the mold. 
b. Outer stator: The slot opening direction is outward. The commonly used winding method is the fly-spike method. The wires enter the slot from the outside, which results in a fast winding speed and high efficiency. 
2. Scope of Application: 
a. Inner winding stator: Suitable for stator products of household appliances, medical equipment, water pumps, stepper servo, and electric tools, etc. 
b. Outer stator: Suitable for motor stators of model aircraft, agricultural machinery, unmanned aerial vehicles, massaging guns, twist wheels, and electric vehicles. 
3. Machine Characteristics: 
a. Inner-rotating machine: It has high precision requirements, operates relatively slowly (up to 800 R/min), and is relatively expensive (typically over 100,000 yuan for a four-position model). 
b. Peripheral motor: It operates at a higher speed (up to 2000 revolutions per minute or more), and the price is relatively lower (generally above 40,000 yuan). 
4. Product Features: 
a. Inner winding machine: Supports customized non-standard large-diameter core winding solutions, and can handle single-strand, double-strand, and triple-strand winding. 
b. Peripheral winding machine: It can operate simultaneously in multiple stations and wind multiple strands of copper wire. The single-strand wiring is compact, and the modular design of the clamping mechanism makes model changeover more convenient.
