Which one is faster, the needle-type inner-winding machine or the lever-type outer-winding machine?

When discussing the selection of winding machine equipment, we inevitably focus on the speed differences between the flywheel external winding machine and the needle-type internal winding machine and the reasons behind them. Here, NOYU provides an in-depth analysis of these two types of winding machines and the key factors to consider when choosing a winding machine.
 

1. Speed Differences and Their Causes

There are significant differences in speed between the flywheel external winding machine and the needle-type internal winding machine. Generally, the speed of the high-speed internal winding machine can reach 800 to 1200 revolutions per minute (R.P.M.), while the high-speed external winding machine can easily exceed the 2500 R.P.M. threshold. This speed difference mainly stems from the fundamental differences in winding methods and mechanical structures between the two types.

1. Needle-type Internal Winding Machine: Specifically designed for stator products with inward slots, it uses complex upward or downward winding methods with hooks. The needle pin and line mouth under servo drive control move up and down, while the mold rotates left and right to ensure the neatly wound wire into the slot. Although this precise operation mode ensures the accuracy of winding, it also limits the speed improvement.

2. Flywheel External Winding Machine: Designed for stator products with outward slots, it adopts a simpler and more direct flywheel winding method. The rapid rotation of the flywheel drives the insulated wire to move, and the cooperation of the stator rod, stator frame, mold head, and guard plate enables the wire to be neatly wound into the stator slot. This more straightforward operation process gives the flywheel external winding machine a significant advantage in speed.

Key Factors for Choosing a Winding Machine:

When selecting a winding machine that suits your production needs, we need to consider the following key factors:

1. Product Requirements: Clearly define the type, specification, and quantity of stator products to be wound. Different products may be suitable for different types of winding machines. For example, stator products with inward slots are more suitable for needle-type internal winding machines, while those with outward slots are more suitable for flywheel external winding machines.

2. Winding Requirements: Based on the winding requirements of the product, such as wire diameter, number of turns, and arrangement method, choose the appropriate winding machine. For products requiring multiple strands to be wound together, a winding machine capable of supporting this function should be selected.

3. Production Efficiency: While pursuing production efficiency, ensure the stability and accuracy of the winding machine. If production efficiency is the primary consideration, a faster flywheel external winding machine may be a good choice; if higher precision is required, a more precise needle-type internal winding machine may be more suitable.

4. Cost Budget: Cost budget is also an important factor to consider when choosing a winding machine. Needle-type internal winding machines are usually equipped with higher configurations and are relatively more expensive; while flywheel external winding machines are simpler and more affordable.Therefore, in cases of limited budget, we need to weigh the performance and price relationship and make a more informed choice.
 

In conclusion, there are significant differences in speed, winding methods, and mechanical structures between the flywheel external winding machine and the needle-type internal winding machine. When choosing a winding machine, we need to consider factors such as product requirements, winding requirements, production efficiency, and cost budget to ensure that the selected equipment meets our production needs and brings good economic benefits.
