What is a frequency inverter?
The frequency inverter is a power control equipment that applies frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor power supply.
How does a frequency inverter change the speed of a motor?
Speed Regulation Function: Frequency inverters can change the speed of the motor by adjusting the frequency of the power supply. This is very important for applications that require flexible speed control, such as in industrial production, where different production processes may require different speeds.
How does inverter speed regulation work?
Inverter speed regulation is achieved by changing the frequency of the power supply to the stator winding of the motor. First, the rectifier section converts the AC power supply to DC power. This usually involves a rectifier bridge, which converts the AC voltage to DC voltage.
How a frequency inverter can improve the power grid?
Improve the Quality of Power Grid: when adjusting the motor operation, the frequency inverter can reduce the impact of the motor on the power grid, and reduce harmonics and the peak value of the current, which helps to improve the power quality of the power grid.
How a variable frequency inverter works?
Reduced Mechanical Shock: The variable frequency inverter reduces the mechanical shock in the system by smoothly adjusting the running speed of the motor, which helps to improve the stability and reliability of the equipment. Helps to improve the stability and reliability of the equipment.
Why should you choose a frequency inverter?
Energy Saving and Emission Reduction: Due to the ability to adjust the running speed of the motor according to the need, the frequency inverter helps to reduce the energy consumption of the system and minimize the waste of energy, thus reducing the carbon emission and conforming to the requirement of sustainable development.
