In the planning of the CNC machine tool of the metal aluminum cnc router machine, the frequency converter is used as the spindle motor drive of the metal aluminum cnc router machine. The first requirement is stable work and smooth speed change. The equipment under the frequency conversion control can complete constant voltage control or constant current control. Full-speed fluctuation is small, low-speed torque is large, and low-speed cutting can be ensured.
The main circuit of the frequency converter can be divided into two categories: the voltage form is to convert the DC of the voltage source into a communication converter, the filter of the DC circuit is a capacitor, and the current form is to convert the DC of the current source to communication, and the filter of the DC loop It is an inductor, which consists of three parts. It converts the power supply into a “rectifier” for DC power supply, a “flat wave loop” to absorb the voltage ripples generated by the converter and inverter, and one that converts the DC power supply into communication power.
The main functions of the frequency conversion device of the metal aluminum cnc router machine are as follows:
1. Speed regulation: Generally, three-phase asynchronous motors can complete the function of speed regulation after adding frequency conversion, that is, the speed of the motor can be changed arbitrarily within a certain range.
2. Energy saving: Compared with the traditional electromagnetic speed control, the frequency conversion speed control saves 25% less than the traditional electromagnetic speed control. The specific energy saving depends on the user’s equipment.
3. Soft start: The inverter start does not damage the mechanical equipment, but the hard start is just the opposite.
It should also be noted here that the equipment and use of the frequency converter of the metal aluminum cnc router machine, that is, in order to meet the voltage matching, the extra voltage of the engraving machine frequency converter and the extra voltage of the load are common; current matching, general centrifugal pumps, frequency converters The extra current of is common to the extra current of the motor. For special loads such as deep-water pumps, you need to refer to the performance parameters of the motor to confirm the inverter current and overload capacity of the cnc router machine.
