    Hi All
    As Usuall I need help. I have an ER11, 300 watt brushless spindle/motor that I aquired.(legit but long story)...And wish to use for a MCB / inlay router. (bed mill, etc.)

    This seems to to be a quality item. All stainless construction and came from a lens grinding machine, so should have low run out and ER11 collet is perfect for the application I need.

    I have contacted Loadpoint and they have been very helpful. But without sending them the motor and the best part of a grand they cant help with the driver.

    Motor Power

    Red wire = Phase A
    White wire = Phase B
    Black wire = Phase C

    Hall sensors

    Thin blue wire = +5V
    Thin brown wire = A
    Thin orange wire = B
    Thin yellow wire = C
    Thin green wire = earth/ground

    Thin purple wires = thermistors (not needed)

    Their best guess is 6 Pole and 180Volt. I have bought a controller from the bay but it is only 100volt max.

    Will this contoller work and how do I make a 100volt psu?

    If not can anybody help? I was hoping that spindle control is easier than servo control and therefore maybe an easyish solution.:whistling:
