    Im not too sure on the specs of the controller, i would just google it to help you find that out. Can i ask what spindle you have? incase i want to upgrade mine later?

    You can, its a bit of a frankenmotor,

    I had an old dc treadmill motor, machined a new front plate for it and bearing housing and assembled the lowest resistance motor i could out of the armatures with the most powerful magnets. I have tested the motor and can get 1.2kW out of it. But could do with finding what the drive can provide.

    The bigger improvement i have done was to change the pulleys and belt to have a higher speed on the spindle. if i was to do it again though i would butcher one of the 400Hz Chinese 3 phased spindle motors and fit one of them. Then get higher speed and higher torque.
