Variable frequency drive (VFD) for engraving machines is a power control device that applies frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply. The frequency converter is mainly composed of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, driving unit, detection unit, microprocessor unit, etc. The frequency converter adjusts the voltage and frequency of the output power supply by disconnecting the internal IGBT, providing the required power supply voltage according to the actual needs of the motor, thereby achieving energy saving and speed regulation. In addition, the frequency converter also has many protection functions, such as overcurrent, overvoltage, overload protection, etc. With the continuous improvement of industrial automation, frequency converters have also been widely used. The energy-saving of frequency converters is mainly manifested in the application of fans and water pumps. In order to ensure the reliability of production, various production machinery are designed with a certain amount of surplus when equipped with power drives. When the motor cannot operate at full load, in addition to meeting the power drive requirements, the excess torque increases the consumption of active power, resulting in the waste of electrical energy. The traditional speed regulation method for equipment such as fans and pumps is to adjust the air and water supply volume by adjusting the opening of the inlet or outlet baffles and valves. The input power is high, and a large amount of energy is consumed in the interception process of the baffles and valves. When using variable frequency speed regulation, if the flow rate requirement is reduced, the requirement can be met by reducing the speed of the pump or fan. The purpose of using a frequency converter for electric motors is to regulate speed and reduce starting current. In order to generate variable voltage and frequency, the device first needs to convert the alternating current of the power supply into direct current (DC), a process called rectification. The scientific term for a device that converts direct current (DC) into alternating current (AC) is "inverter". A general inverter is an inverter that converts a DC power supply into a fixed frequency and voltage. For inverters with adjustable frequency and voltage, we call them frequency converters. The waveform output by the frequency converter is an analog sine wave, mainly used for speed regulation of three-phase asynchronous motors, also known as frequency converters. For variable frequency inverters with high waveform requirements mainly used in instrumentation detection equipment, the waveform needs to be organized to output standard sine waves, which is called a variable frequency power supply. Generally, the price of a variable frequency power supply is 15-20 times that of a variable frequency drive. Due to the fact that the main device that generates voltage or frequency changes in the frequency converter equipment is called an "inverter", the product itself is named an "inverter", that is, a frequency converter. Frequency conversion cannot save electricity everywhere, and there are many occasions where frequency conversion may not necessarily save electricity. As an electronic circuit, the frequency converter itself also consumes power (about 3-5% of the rated power). A 1.5-horsepower air conditioner consumes 20-30 watts of electricity, equivalent to a constant light It is a fact that frequency converters operate at the power frequency and have energy-saving functions.
