Product Description:
The AKMH31E-ACKNCA1K is a hygienic stainless-steel servomotor produced by Kollmorgen within the AKMH Stainless Servomotors series. Designed for wash-down environments, the motor drives rotary motion in automated food, beverage, and pharmaceutical machinery where frequent high-pressure cleaning is required. Its sealed construction and corrosion-resistant materials allow direct mounting on equipment frames, so a separate enclosure is unnecessary. Its smooth exterior helps reduce places where water and residue can collect during sanitation cycles.
Electrical and mechanical limits define its performance envelope. A rated speed of 6000 rpm allows rapid cycle times in indexing or continuous-flow processes, while the available peak torque of 3.88 Nm supplies short bursts of extra shaft force for acceleration or cutting loads. The enclosure has an IP69K protection class, meaning it withstands 100 bar water jets at close range without moisture ingress. Corrosion resistance comes from the housing’s 1.4404 (316L) stainless steel alloy, which tolerates aggressive detergents and eliminates paint flaking. These attributes combine with flange mounting in accordance with IEC patterns, so the motor can replace conventional painted units without redesigning the machine interface.
High-demand motion profiles are supported by a peak winding current of 12.0 A and a continuous winding resistance of 4.76 Ω, values that guide drive sizing and thermal modeling. The compact mechanical interface uses a flange diameter of 89 mm and a closed-keyway shaft. The closed-keyway shaft provides positive torque transfer for couplings used in compact process machinery. Feedback comes from a Smart Feedback Device (SFD3) encoder, enabling a single-cable connection to AKD drives for position and condition data. That arrangement reduces external cabling around conveyors, augers, and dosing pumps. System bus links may operate up to a maximum of 320 VDC. The sealed shaft area uses a mineral-filled PTFE O-ring to support hygienic wash-down service.
