Product Description:

The AKMH63H-ACKNCA1K is a hygienic stainless steel servo motor produced by Kollmorgen for the AKMH Stainless Servomotors series. Built as a washdown-rated rotary actuator, it connects directly to AKD drives through a preassembled cable and returns position data through a Smart Feedback Device 3 encoder. In automated filling, cutting, or packaging stations, the motor provides closed-loop torque and speed control so equipment can maintain repeatable motion cycles after high-pressure cleaning. The sealed stainless housing suits food and beverage machinery that requires frequent sanitation.

Its enclosure is rated at IP69K, allowing exposure to high-pressure spray at 80 °C without moisture ingress. Under continuous load, the motor produces 14.6 N·m while drawing 5.4 Arms. With a torque constant of 2.73 N·m/Arms, the drive can relate commanded current to output torque. The back electromotive force of 194.5 Vrms/kRPM is important when selecting bus voltage and regenerative hardware. Motion feedback is provided at 11-bit resolution through the SFD3 device, while the windings have 3.45 Ω resistance. A 62-minute thermal time constant and mineral-filled PTFE insulation help slow heat buildup and reduce condensation paths.

For transient positioning moves, the motor can develop 44.7 N·m of peak torque. Its mass of 23.1 kg adds thermal inertia, and the stator coils have 28.1 mH inductance to smooth high-frequency inverter pulses. A flange diameter of 186 mm with a 130 mm pilot matches IEC flange-mount layouts, and an FDA-approved O-ring seals the interface. The closed-keyway shaft is 32 mm in diameter and uses a shaft seal suited for washdown service, while the surface finish remains below 0.8 µm. The 1.4404 stainless housing uses IM B5 mounting and conforms to DIN 748 and DIN 6885-1. Rotor inertia is 0.00242 kg·m², rotor length code is 3, and the overall assembly length is 1 m.
