A frequency converter is a device that can change the speed of a motor. Its basic working principle is to adjust the speed of the motor by changing the frequency of the power supply, so as to achieve the purpose of energy saving, speed regulation and protection of equipment.
When the inverter receives the control signal, it calculates the required output voltage and frequency according to the set parameters, and converts this information into an electrical signal to send to the inverter. The inverter adjusts the on-on and off-time of the switching device so that the current is output according to a specific waveform, so as to drive the motor.
During use, the inverter can be adjusted according to different needs, such as changing the speed of the motor under light or heavy loads, or providing additional acceleration during starting. In addition, the inverter can also detect the working status of the motor and send out an alarm in time in case of failure to protect the safety of the equipment.
In general, the inverter is a very practical electrical equipment, which is widely used in various industrial occasions, such as metallurgy, chemical industry, electric power and other fields, and its efficient, flexible and safe characteristics make it an important part of modern production.
