Product Description:

The AKMH24F-ACKNCA1K is a hygienic stainless-steel washdown motor produced by Kollmorgen for the AKMH Stainless Servomotors series. Built for sanitary automation, it attaches to an AKD drive through a preassembled one-meter cable and converts bus power into precise rotary motion on food, beverage, and pharmaceutical lines. Its stainless-steel exterior is intended for equipment that is cleaned frequently and exposed to moisture during routine sanitation. Smart Feedback Device encoder technology returns 11-bit position data, and the design omits a holding brake to reduce mass and simplify washdown sealing.

The winding tolerates a maximum bus of 320 VDC, and the six-pole rotor delivers a peak torque of 5.39 Nm when the amplifier supplies 15.6 A. Continuous operation at standstill requires 1.125 Nm with 3.42 A, in line with a torque constant of 0.35 Nm/A. Back-EMF is specified at 23.4 Vrms/kRPM, which helps set drive voltage scaling. The rotor’s mass moment of 0.27 kgcm² supports rapid indexing without overshoot, and this combination supports quick acceleration with repeatable motion. Electrical behavior is influenced by 6.16 mH of inductance and 2.96 Ω of resistance, and heat accumulation follows a 37-minute thermal time constant.

The housing is machined from 1.4404 stainless steel with surface roughness below 0.8 µm, and an FDA-approved O-ring seals the 79 mm flange. A 40 mm pilot aligns the IEC IM B5 mount, while the closed-keyway shaft measures 11 mm and uses an IP69K shaft seal made from mineral-filled PTFE. The low surface roughness helps reduce residue retention on exposed exterior surfaces. Overall weight is 5.1 kg, and frame size AKMH2 with rotor length code 4 complies with DIN 748 and DIN 6885-T1 geometry. The enclosure has an IP69K rating, allowing sustained high-pressure, high-temperature wash cycles in food-grade zones.
