The role of the inverter

The frequency converter integrates high-voltage, high-power transistor technology and electronic control technology and is widely used. The function of the frequency changer is to change the frequency and amplitude of the power supply of the AC motor, thus changing the cycle of its moving magnetic field and achieving the purpose of smoothly controlling the rotation speed of the motor. The appearance of the frequency converter makes the complex speed control simple, and replaces most of the work that can only be done with a DC motor with a combination of an inverter + AC squirrel-cage induction motor, which reduces the size, reduces the maintenance rate, and makes the drive The technology has developed to a new stage.

The frequency converter can optimize the motor operation, so it can also play a role in improving energy efficiency. According to estimates of ABB, a world-famous inverter manufacturer, inverters that have been produced and installed by the group worldwide have been able to save 115 billion kWh of electricity each year, and correspondingly reduce 97 million tons of carbon dioxide emissions. This has exceeded Finland's one year. Carbon dioxide emissions.
