Ex-Cell-O Spindle Wizard to retrofit

[usfwalden]

I think it has to actually use the commutation signals from the motor to correctly generate the sinusoidal command signals the s series amps require.  I don't really know and am not ready to invest too much time into it.  I've just been seering a lot more big s series than b series amps for sale and figure their might be a cool doodad out there to run them that you have to ask to find out about...like the pico fanuc encoder converter I got for the motor.

CUI has come out with a programmable BLDC  commutation version that is cheaper than the Pico, the pole count, phase direction and encoder resolution is programmable. The commutation to stator phase relationship is simply done by energizing A & B phase with a DC voltage to orient the rotor, and then the info is stored in flash memory.
The technology is the same as used by Mitotoyo in their digital calipers.
