Exclamation Brushless DC Motor Power Question

Hi,

I have been given a brushless 40v DC motor and I was interested in using it for a small hobby lathe.

hxxp://www.dunkermotoren.com/default.asp?id=10&mid=19&lang=2

There are two sleeves coming from the motor.

One with Black, Brown and Blue wires

and another with six smaller wires, Black, Green, Brown, Red, Grey and yellow.

I'm guessing the six wires are for some kind of sensor/speed control and 3 wires for power. Do I need some kind of special power supply for this to function. Below are 2 PDF with some details.

Kind Regards

Stuart

Welcome to the forums.

That is a special purpose three phase motor. The six wire bundle is for the windings and the three wire bundle is for speed monitoring.

A power supply to run this motor would need to be three phase, 40 volts and would probably cost several hundred dollars if you could find the correct one.

Thanks

Cheers for the quick reply, so essentially pointless even thinking about using this for my project, just thought as it was a freebie it was worth a try.

Thanks again

Stuart

Those types of motors turn up all the time as freebies or for very low cost due to the high cost of powering them.

I'd look for a more appropriate motor.... possibly on eBay.
