Can you avoid Tripping a breaker using Transformer?

[Braren]

Hi all,

I'm currently building a CNC Machine that uses a 2hp 110 or 220 V Motor. Recently I had to move it to the shed in order to make room in the garage, but now I'm using a 50ft extension cord to power the machine, and it is drawing a little too much current when the spindle is running at max rpm and it trips the breaker, I think this is due to the added resistance of the extension cord. I can run at lower rpm's but I can tell that the motor is working pretty hard.

If I use a 110 primary to 220 secondary transformer to run the motor, could this potentially help me run the motor without tripping the breaker?

I'm electrically challenged, so please let me know if my question is ridiculous

Thanks!

I think you need more copper in the wires going out to the CNC machine... See the following:

Wire Voltage Drop Design and Calculator

Figure our how much current at what voltage you need and then add a safety factor to it and build...

The three other options I would consider are:
Installing a chopper on the DC bus to regulate the voltage
You can use transformer which re-wound for 11kV
Use 5-winding transformer
