Product Description:
The AKMH24E-ACKNCA1K servomotor is produced by Kollmorgen within the AKMH Stainless Servomotors series. As a hygienic stainless steel washdown motor, it is intended for food, beverage, and pharmaceutical automation where frequent high-pressure cleaning is required. The motor provides direct rotary actuation in servo loops driven by AKD amplifiers, eliminating the need for additional protective enclosures on machines. Its stainless exterior and sealed construction suit exposed installation in processing areas where regular washdown is part of normal operation. This design is also suitable for conveyors, fillers, and packaging equipment installed in sanitary production zones.
The unit reaches a maximum shaft speed of 8000 rpm and supports an allowable DC bus up to 320 Vdc. At a winding temperature of 100 °C, it can sustain 1.12 Nm of stall torque while drawing 2.39 A rms; at 60 °C, the continuous capability is 0.893 Nm because copper resistance, measured at 5.46 Ω line to line, rises with heat. Peak demand reaches 14 A rms and produces 5.51 Nm for rapid indexing moves. A back-electromotive-force constant of 32.4 V/krpm corresponds to the generated voltage returned to the AKD drive. The matched Smart Feedback Device (SFD3) encoder delivers 11-bit resolution, and its preassembled hybrid cable simplifies connection. The motor uses winding type E, rotor length 4, and the AKMH2 frame for its electromagnetic design, and it does not include an integral holding brake. A 79 mm flange with IEC B5 mounting mates to a 40 mm pilot, while mineral-filled PTFE forms the FDA-approved O-ring that seals the flange and a shaft seal protects the 11 mm closed-keyway shaft.
For corrosion resistance, the housing is machined from 1.4404 (316L) stainless steel with a surface finish below 0.8 µm. The smooth surface helps reduce residue buildup on exposed exterior areas. The assembly keeps the IM B5 face-mount geometry used in DIN 748 and DIN 6885 T1, which supports direct mounting on compatible machine plates and gearbox adapters. With enclosure rating IP69K, both the casing and the dedicated shaft seal withstand 100 bar water jets at 80 °C. A torque constant of 0.50 Nm/A rms gives predictable load response during servo operation.
