What are the characteristics of brushless motor stator internal and external winding machine? How to choose a high quality winding machine equipment?

The main difference between brushless motor stator internal winding machine and external winding machine lies in the type of stator products, precision, configuration requirements and winding method.

Types of stator products: The internal winding machine is mainly for stator products with inward slots, such as electric tool motors, household appliance motors, medical equipment motors, water pump motors, servo motors, stepping motors, etc. The external winding machine is mainly for stator products with outward slots, such as aeromodelling motors. The external winding machine is mainly for stator products with slots facing outward, such as aeromodelling motors, drone motors, twisted car motors, planting machine motors, scooter motors, cooling fan motors and so on.

Precision: The inner winding is more precise and complex than the outer winding products, and the price is more expensive than the outer winding machine. The outer winding structure is relatively simple.

Configuration requirements: the configuration of the inner winding machine generally use high-quality spare parts, such as Panasonic Fuji servo motors, Delta, Mitsubishi controller, etc., the price will be higher. The configuration of the outer winding machine can be based on demand, the price of the machine will be cheaper.

Winding method: the inner winding machine mainly adopts the needle winding method, through the needle bar line nozzle with the enameled wire, can move up and down, can also move up and down, with the mold and the line mechanism to cooperate with each other, so that the line will be neatly wound to the stator. The external winding machine mainly adopts the flying fork winding method, the flying fork wire nozzle with enameled wire, high-speed rotation, through the die head, molds, guard plate mutual cooperation role, so that the wire circle by circle into the stator slot.

When selecting a quality winding machine equipment, you can choose according to your needs and budget. Generally speaking, if you need precision winding requirements, you can choose internal winding machine with professional servo motor and drive control system. If the requirement of winding precision is not high, you can choose the external winding machine and select the appropriate configuration according to the need.

In short, selecting quality winding machine equipment needs to be based on their actual needs and budget to choose the right model and configuration.
