3 phase joining in series, possible??

[Oxieee]

Hello good people.

I need to run a brushless motor on an esc but the equivalent speed controller is three times the price of motor.

I was wondering if it is possible to connect TWO output 3 phase current in series in an effort to stack up the voltage together.

Thanx alot....have no idea about 3 phase currents :P:P:P

cant understand your query ...

No, you can't connect the phases of a 3 phase supply in series because they are joined at the neutral.

Take this example with batteries,

The negative terminals of the batteries are joined together (with the black wire at the bottom), and to connect them in series would mean connecting the red wire as shown.

This would short out the left battery.

This is similar to the situation with 3 phase circuits.

However, the voltage between phases of a 3 phase system is 1.73 times the individual phase voltage and this isn't much less than twice the phase voltage.

If you have no idea about 3 phase circuits, you should definitely not be connecting anything to them.
