Machine tool control

Modern industrial enterprises, widely used as power, in the process of machine tool production, will frequently convert voltage levels to meet the needs of industrial manufacturing, where the main application is the transformer.

It serves two main purposes:

1. Isolation: eliminate the harmonics in the power grid, improve process accuracy, ensure personal and electrical equipment safety

2. Transformer: to meet the needs of different voltage levels, to achieve accurate control according to the actual use of different functions can be subdivided, in CNC machine tools, the main transformer used are: 1. Servo transformer: primary 3N380V, secondary 3N200V, to supply power to the servo amplifier (servo drive) .

2. Control Transformer: Input 380V, output AC220V, AC110V, AC24V a group, respectively, supply air conditioner, switching power supply, AC contactors, lighting, etc. .
