5500 watt variable frequency motor with rated current 11.2A/ 12A/ 13.4A and 2.8 Tmax/ Tn maximum torque/ rated torque.
Tips: Working Principle of Variable Frequency Motor.
Inverter is an electric energy control device that uses the on-off action of power semiconductor devices to transform a power frequency power supply into another frequency. At the beginning of the 21st century, the frequency converter used mainly adopts AC-DC-AC (VVVF frequency conversion or vector control frequency conversion). First, the industrial frequency AC power supply is converted into DC power supply through the rectifier, and then the DC power supply is converted into frequency and voltage. Control AC power to supply the motor. The circuit of the frequency converter is generally composed of four parts: rectification, intermediate DC link, inverter and control. The rectification part is a three-phase bridge uncontrollable rectifier, the inverter part is an IGBT three-phase bridge inverter, and the output is a PWM waveform, and the intermediate DC link is filtering, DC energy storage and buffering reactive power.
