In the design of aluminum cnc router, the frequency converter is used as the spindle motor drive of the aluminum cnc router, which mainly requires stable operation and stable speed change. The frequency conversion control equipment can realize constant pressure control or constant current control, with small fluctuations at full speed and large torque at low speeds, ensuring low-speed cutting.
The main circuit of the frequency converter can be divided into two types: voltage mode is to convert the DC power of the voltage source into an AC converter, the filter of the DC circuit is a capacitor, and the current mode is to convert the DC power of the current source to AC, and the filter of the DC circuit It is an inductor, which consists of three parts. It converts the power supply into a "rectifier" for DC power supply, and a "smoothing loop" absorbs the converter and the voltage ripple generated by the inverter, and converts the DC power supply into an AC power supply. "Inverter".
The main functions of the frequency conversion device of the aluminum cnc router are as follows:
1. Speed regulation: ordinary three-phase asynchronous motors can realize the speed regulation function after adding frequency conversion, that is, the motor speed can be changed arbitrarily within a certain range.
2. Energy saving: Compared with traditional electromagnetic speed regulation, frequency conversion speed regulation saves less than 25% energy compared with traditional electromagnetic speed regulation. The specific energy saving depends on different user equipment.
3. Soft start: The inverter start is harmless to the mechanical equipment, and the hard start is the opposite.
It should also be noted that the configuration and use of the aluminum cnc router inverter, that is, in order to meet the voltage matching, the rated voltage of the cnc router inverter is consistent with the rated voltage of the load; the rated current for current matching is generally a centrifugal pump and a frequency conversion The rated current of the motor is the same as that of the motor. For special loads such as deep-water pumps, it is necessary to refer to the performance parameters of the motor to determine the inverter current and overload capacity of the cnc router.
The above is the method of controlling the frequency conversion of the aluminum cnc router. If you have any questions about the cnc router, you can directly consult our online customer service.
