     1= CMC (Cleveland Motion Controls, Torque Systems) T0604B9100 MDM-5000 Series BLDC Servo Motor = 
     2[[Image(http://factoryswblog.org/wp-content/uploads/2013/CMC_MDM5000.jpg)]][[BR]]

     4I've been interested in MDM5000 motors for a long time; when Excess Solutions had some for sale, I snapped up a couple.

     6CMC is now part of ITT.  I believe Torque Systems was a division of CMC, but it looks ITT has changed all the motor branding from CMC to Torque Systems.  Anyway, the documentation for the [http://www.torquesystems.com/mdm-5000-brushless-servo-motor.asp MDM-5000 series] is at the Torque Systems website.

     8The T0604B9100 is a quadruple stack 60mm metric mount servo motor.  I suspect it has a custom winding, since the second part ("B9100") of the part number isn't similar to any current standard part numbers.  The winding appears similar to the B3 winding. 
     9 
     10The encoder is a Torque Systems Datatorque 14414-805 with 8000 quadrature counts per revolution.  I can't find that part number, either, but it appears to be similar to the Datatorque HS15, with the same pin out. 
     11 
     12The motor is a high density motor, with a lot of torque for its size.  However, it seems to have substantial cogging torque; if you need a super-smooth motor, you're best off looking elsewhere.

     40The motor uses a commutating encoder; see below for commutation signals.

     42=== Encoder === 
     43 
     44My standard is positive is when the motor, when viewed from the front, is turning clockwise. (My A+/A- connections are flipped when compared to the Datatorque HS15 wire colors).  
     45When possible, my commutation sensor order is chosen to work with an AMC BE15 analog servo amplifier.
