Gecko BLDC drive

No pressure, Mariss, but how are things coming on the BLDC drive?

If those encoders are the ones on the
Shinano Kenshi LA052-040E4N02 (40 Watt?) BLDC
(brushless DC) motors,

then I believe this is the pinout (credit due to Brian):

orange w red - /B +5V
orange w black - G GND
pink w red - /Z signal A
pink w black - /A signal B
yellow w red - /R signal Z
yellow w black - S signal C1
grey w red - /P signal C2
grey w black - /Q signal C3
black no conn shield

I think A & B are your two quadrature signals,
Z is your one-pulse/rev index signal, and
C1,C2,C3 are hall effect signals to feed
a brushless motor controller.

As a side note, I think Mariss was working on
a brushless motor controller last fall for
exactly this motor/enocoder combination.

Using the treadmill motor should work great using G3xx
(although it is a 120VDC motor, it runs with
great vigor directly connected to my 75VDC supply).
