The Beckhoff AM3011 is a compact, cute little single stack 40mm flange brushless servo motor with resolver feedback. The circular connectors are almost as big as the motor. It's my only motor with a resolver; other unusual features for such a small motor include high pole count (6 poles; 4 poles is normal for this size) and high voltage (230V; most of my motors are <100V). The Beckhoff datasheet is here (PDF).

I will update this section when I have tested the motor with a servo drive (I do have a B&R servo drive with resolver feedback).
