Kollmorgen AKM21C-ANS2GB02
Product Introduction:
The AKM21C is the smallest frame in the AKM lineup (Flange ≈ 42 mm). Winding “C” is typically a low-voltage or 120 V class winding suited for 48 VDC bus or 115/230 VAC with appropriate drive. The ANS2GB02 configuration typically means: AKM2 frame, winding C, S—feedback (often resolver or single-cable encoder), 2—smooth or keyed shaft with standard seal, G—no brake or specific connector config, B02—special paint/option code.
