# Variable Frequency Drive Circuit

I want to make a low-cost solution regarding the control of a three-phase AC asynchronous motor. I want to be able to control it using an Arduino board(set the frequency from it).

Motor specification:

• Power: 0.3KW
• rotations: 1400
• Nominal current 1A at 220Vac/0.6A at 400V

I am relatively new into power-electronics, so it would be highly appreciated if you could tell me what circuits would I need?

So far I understood that I need an inverter circuit for the 3 phases of the motor. Do I need special controllers for every IGBT or can I control all of them from the Arduino?

Also, is this schematic remotely ok? If not, where could I find a complete schematic?
