Select the frequency conversion speed regulation method. Automatic winding machine frequency conversion speed regulation is a speed regulation method, which changes the frequency of the motor stator power supply and changes its synchronous speed. Automatic winding machine features: Automatic winding machine
1High efficiency during speed regulation without extra loss;
2 Wide range of application, can be used for cage asynchronous motors;
3 Large speed range, hard features and high precision.
Transformer usually consists of core, coil, shell and necessary insulation materials. The transformer coils are usually divided into high-voltage coils and low-voltage coils. High voltage coils are usually wound with round insulated wire, and low voltage coils are usually wound with flat insulated wire or foil stomach. Transformer coil winding is the core process of transformer manufacturing and has a great impact on the performance of the transformer. It not only directly determines the main economic and technical indicators such as external dimensions, losses and weight of the transformer, but also directly affects the main quality indicators such as mechanical properties, insulation performance and heat resistance of the transformer. Conventional transformer coils are wound by hand to wind the insulated wire onto the workpiece according to the production process requirements and the operator calculates the number of resistances. With the traditional winding method, not only the winding efficiency is low, but also the quality of the finished coil is poor. Current transformer coil winding is usually used in conjunction with automatic winding machines, which can significantly improve production efficiency and wiring accuracy. Among the automatic winding machines, there are vertical winding machines for winding large transformers, and horizontal and foil winding machines for winding low-voltage grade and small-capacity transformers.
