Product Description:
The AKMH54P-ACKNCA1K is a hygienic stainless steel washdown servo motor produced by Kollmorgen within the AKMH Stainless Servomotors series. In food, beverage, and pharmaceutical automation, this motor provides rotary power while tolerating frequent cleaning. Its sealed stainless construction and IP69K protection allow the unit to operate in processing zones without extra housings. The drive-compatible design supports precise positioning tasks that run continuously in wet or caustic environments. This makes it suitable for conveyors, fillers, and other sanitary motion systems that require accurate servo control.
At a rated speed of 3000 rpm, the motor delivers 2258.8 W and can provide a continuous stall torque of 11.8 N-m at 16.68 Arms. During acceleration, it can reach 38.13 N-m, and the windings can accept up to 58.8 Arms. The motor has a torque constant of 0.722 N-m/Arms. It uses an AKMH5 frame with a 148 mm flange and a 110 mm pilot for IEC flange mounting in IM B5 form, and the closed-keyway shaft has a 24 mm diameter to DIN 748 and DIN 6885 T1. The overall motor diameter is 132 mm. Rotor inertia is 0.00119 kg·m², rotor length code is 4, and position feedback is provided by a Smart Feedback Device (SFD3) with 11-bit resolution. A pre-assembled AKD drive cable that is 1 m long reduces installation time.
The electrical model has a back-emf constant of 47.3 Vrms/kRPM, a resistance of 0.32 ohm at 25 °C, and an inductance of 1.49 mH. These values help the drive regulate current response. The one-piece housing is machined from 1.4404 (316L) stainless steel with a surface roughness below 0.8 µm, and all exterior elastomers use mineral-filled PTFE for chemical resistance. An FDA-approved O-ring seals the flange, and a shaft seal guards the 24 mm journal during washdown. Because the motor does not include a brake, axial length and inertia are kept lower. The smooth exterior also helps liquid drain during high-pressure cleaning.
