Frequency inverter & servo

 With the continuous progress and development of electronic technology, the development of frequency inverter technology and its equipment is also gradually improved. More and more new technologies and materials are applied in the development of frequency inverter, which further solves the problem of high voltage in the operating circuit. Frequency inverter is used to change the frequency and amplitude of AC motor power supply, so as to change the cycle of its moving magnetic field and achieve the purpose of smooth control of motor speed. The frequency inverter adjusts the voltage and frequency of the output power supply by switching off the internal IGBT, and provides the required power supply voltage according to the actual needs of the motor, so as to achieve the purpose of energy saving and speed regulation. In addition, the frequency inverter has many protection functions, such as overcurrent, overvoltage, overload protection and so on.

Frequency inverter is an electric energy control device that uses the on-off action of power semiconductor to change the current frequency. It is divided into high-voltage and low-voltage frequency inverter according to its purpose. With the popularization of industrialization and automation, the products of frequency inverter are widely used, including photovoltaic and wind power converter on the power generation side. In terms of application, high-voltage frequency inverters are mainly used in high energy consuming industries such as metallurgy, electric power, water supply, petroleum, chemical industry, coal and so on. Low voltage frequency inverters are used in logistics, elevator, fan, textile and printing industries.
