Hi, can i control 380V(approximately 1kw) three phase electric motor whit arduino, not intrested in speed just intrested in direction.
Control of High Voltage 3-Phase BLDC Motor
They have this thing called Google now.
with 2 contactors it can be done (each with 3NO and 1NC contacts)
If contactors take high voltage AC an additional 2 SSRs will do the trick.
The NC-contact is used to disable trigging of the other to avoid short circuits.
It may be a good idea to select contactors with delayed start.
an other alternative is two SSRs eg like theese
Hi, you can even get pairs of mechanically interlocking contactors that will only operate one at a time.

Thnx i will try idea of knut_ny. I have made miniature greenhouse, whit leds and servo motor, now i will try same only whit big power. I ima replacing 5v servo motor with 380V(1 KW) motor.I hope it will work.
