Product Description:

The AKMH23D-ACKNCA1K is a hygienic stainless steel washdown motor produced by Kollmorgen in the AKMH Stainless Servomotors series. A 1.4404 (316L) housing, an IP69K shaft seal, and mineral-filled PTFE static seals let the unit withstand CIP and high-pressure sanitation. Classified as a hygienic stainless steel washdown motor, it uses frame size AKMH2 hardware and mounts on an IEC flange to supply closed-loop torque and speed for food, dairy, and pharmaceutical automation.

Electrical performance centers on continuous output. At stall, the rotor develops 0.85 N·m while the winding draws 1.88 Arms; these figures correspond to the D winding and a torque constant of 0.485 N·m/Arms. The laminated core offers 17.3 mH of inductance and a winding resistance of 8.79 Ω, enabling the matched AKD drive to limit current transients. The motor has an ingress protection rating of IP69K for direct hose-down service. Feedback comes from an SFD3 encoder with 11-bit resolution, and a one-meter preassembled cable connects straight to the drive. The motor is supplied without a holding brake, so static load retention depends on drive torque.

Mechanical attributes support hygienic duty and quick axis response. The motor has a 79 mm flange with a 40 mm pilot, IM B5 orientation, and a closed-keyway shaft. That shaft is 11 mm in diameter and uses an IP69K shaft seal, while surface roughness stays below 0.8 µm. Momentary overloads can be handled with 3.75 N·m of torque, and acceleration is supported by a back-EMF constant of 33.8 Vrms/kRPM and a rotor inertia of 0.0000216 kg·m². The rotor length code is 3, the overall motor diameter is 74 mm, and an FDA-approved O-ring secures the flange. Mineral-filled PTFE is used for the static seals, and the geometry follows DIN 748 and DIN 6885 T1 while matching IEC flange mounting.
