Parker Compumotor CM232BE-00480B (custom SM232BE) NEMA23 Brushless Servo Motor

http://factoryswblog.org/wp-content/uploads/2013/Compumotor_CM232.jpg

The CM232BE-00480B is a customized version of the Compumotor SM232BE. Click here for a discussion of Parker's custom servo motors. The first part (CM232BE) specifies the basic motor type, field winding, and feedback. The second part is a sequential number. I suspect that the connector was customized for this motor; I've replaced them with my standard connectors.

So the CM232BE is a triple stack NEMA23 flange SM series servo motor with B winding and 4000 quadrature count/rev encoder feedback. The SM series have slotless stator design that eliminates detent torque. It's much smoother than my MDM5000.

I could not find a datasheet for the 77822-073, but I think it's similar to the Renco RM15; the wire colors match up pretty well.
