What are the characteristics of the inner winding machine and the outer winding machine for brushles

The main differences between inner-wound and outer-wound stator designs for brushless motors lie in the types of stator products targeted, the level of precision, the configuration requirements, and the winding methods. Now, NOYU will briefly introduce this to everyone! 
 

Stator product type: Inner-wound machines are mainly for stator products with inward slots, such as motor components for power tools, household appliances, medical devices, water pumps, servo motors, stepper motors, etc. Outer-wound machines are mainly for stator products with outward slots, such as model aircraft motors, unmanned aerial vehicle motors, twisty vehicle motors, agricultural spraying machine motors, skateboards, and cooling fans. 
Precision level: Compared to the outer winding product, the inner winding is more complex and precise, and its price is also higher than that of the outer winding machine. The outer winding structure is relatively simpler. 
Configuration requirements: The internal winding machine is generally equipped with high-quality components, such as Panasonic Fujitsu servo motors, Delta and Mitsubishi controllers, etc. The price is usually over ten thousand yuan. The configuration of the external winding machine can be determined according to the requirements, and the price of the machine ranges from four to ten thousand yuan to over ten thousand yuan. 
Winding method: The inner winding machine mainly adopts the needle-type winding method. The needle rod and the wire mouth carry the enameled wire, which can move up and down or down and up. It cooperates with the mold and the line arrangement mechanism to neatly wind the wire onto the stator. The outer winding machine mainly adopts the flywheel-type winding method. The flywheel line mouth carries the enameled wire and rotates at high speed. Through the interaction of the mold head, the mold, and the protective plate, the wire is wound layer by layer into the stator slot. 
When choosing high-quality winding machine equipment, you can make the selection based on your own needs and budget. Generally speaking, if you require precise winding conditions, you can opt for an inner winding machine and pair it with a professional servo motor and drive control system. If the requirement for winding accuracy is not high, you can choose an outer winding machine and select the appropriate configuration as needed. 
 

In conclusion, when choosing high-quality winding machine equipment, it is necessary to select the appropriate model and configuration based on your actual needs and budget.
