The Saga that is my Conquest mini-lathe re-furb.

[Make Everything]

Although I know how it works,But I can not build it, he is more than my knowledge and ability，The motor is the same as the computer's hard drive motor， in Industrial products, usually using arm cpu control。
I think maybe you can buy a 50v BLDC driver, check the windings, try it can work at low voltage, or make low voltage winding for it ,Brushless motor winding is very simple, you can refer to some brushless motor design method, you only need some enameled wire and calculation

Make Everything,
thank you, still busy googling to find a suitable circuit or commercial unit for my needs. Luckily i am not in any hurry :-)

it seems that the control IC's are all low voltage but can act as controls for high power MOSFETS that actually power the motor, so i live in hope
thanks for your support
