<p>Inverters are used in many industries. With the development of electronic technology, the inverter market has increased year by year in recent years, the performance of inverters is getting better and better, the technical content of inverters is getting higher and higher, and the scope of application is also increasing. The wider.</p><p><br></p><p> Frequency conversion speed regulation has been recognized as one of the most ideal and most promising speed regulation methods. The main purpose of using 4 frequency converters to form a variable frequency speed control transmission system is to meet the requirements of improving labor productivity, improving product quality, improving equipment automation, improving quality of life and improving the living environment; second, to save energy and reduce production costs . The specific advantages of using frequency converters are described below.</p><p><br></p><p>1. Energy saving by frequency conversion speed regulation</p><p><br></p><p>After the variable frequency speed regulation is adopted, the energy saving effect of fans and pumps is the most obvious, and the power saving rate can reach 20% to 60%. This is because the power consumption of the fan and pump is proportional to the cube of the speed. When the user needs When the average flow rate is small, the rotation speed of the fan and water pump is low, and its energy saving effect is also very considerable. When the traditional baffle and the gate are used for flow adjustment, the power consumption does not change much. Because there are many such loads, which account for about 20% to 30% of the total capacity of the AC motor, their energy saving is very important. For some constant torque loads running at low speeds, such as conveyor belts, Aosheng variable frequency speed regulation can also be used to save energy.</p><p><br></p><p>2. Advantages of frequency conversion speed regulation in motor operation</p><p><br></p><p>Variable frequency speed regulation is easy to realize the forward and reverse rotation of the motor. Only need to change the switching sequence of the inverter tube inside the inverter, the output commutation can be achieved, and there is no problem of burning the motor due to improper commutation.</p><p><br></p><p>Frequency conversion speed control system starts mostly from low speed, and the frequency is lower. The acceleration and deceleration time can be set arbitrarily, so the acceleration and deceleration time is relatively smooth, the starting current is small, and a higher frequency can be started and stopped.</p><p><br></p><p>Recommended to use <a href="https://www.vectorque.com/customized-low-voltage-vfd-inverter-for-speed-control-v-t-technologies" rel="noopener noreferrer" target="_blank">V & T Technologise inverter</a>. When the variable frequency speed regulation system brakes, the V & T Technologise frequency converter can use its own braking circuit to consume the energy of the mechanical load on the braking resistor, and can also be fed back to the power supply grid. Big. In addition, the V & T Technologise frequency converter also has a DC braking function. When braking is required, the frequency converter applies a DC voltage to the motor for braking without additional braking control circuit.</p><p><br></p><p>3. Application for the purpose of improving process level and product quality</p><p><br></p><p>In addition to the application of fans and pumps, frequency conversion speed regulation can also be widely used in various mechanical equipment control fields such as transmission, winding, lifting, extrusion, and machine tools. The use of frequency conversion speed regulation can improve the product yield, extend the normal working cycle and service life of the equipment, simplify the operation and control system, and some can even change the original process specifications, thereby improving the control level of the entire equipment.</p>
