Product Description:

The AKMH44H-ACKNCA1K hygienic stainless steel washdown motor is produced by Kollmorgen within the AKMH Stainless Servomotors series. Intended for sanitary conveyors, fillers, and packaging axes, it uses a 1.4404 (316L) stainless housing, an IP69K protection class, and a surface roughness below 0.8 µm to withstand high-pressure cleaning. Frame size AKMH4, IEC flange mounting, and the IM B5 style enable direct installation. A closed-keyway shaft is supplied without a holding brake, which helps keep the motor suitable for washdown-oriented machine layouts.

The electromagnetic profile centers on a continuous stall current of 5.23 Arms, which indicates the thermal load at a locked rotor, and it delivers a continuous stall torque of 5.4 N-m. For acceleration, the windings accept 22.4 Arms. A back-emf constant of 68 Vrms/kRPM relates shaft speed to the voltage returned to an AKD drive, while the torque constant of 1.05 N-m/Arms relates commanded current to torque output. Magnetic behavior is further characterized by an inductance of 9.05 mH and a DC resistance of 2.25 Ω, which affect current ripple and drive filtering. Position data come from an SFD3 encoder with 11-bit resolution, and a pre-assembled 1 m cable mates directly to AKD connectors through a mineral-filled PTFE gland.

Peak stall torque reaches 20.21 N-m for rapid indexing, and a rotor inertia of 0.000273 kg-m² supports high-bandwidth motion. The flange diameter of 114 mm locates to an 80 mm pilot with an FDA-approved O-ring, while a 19 mm shaft is protected by an IP69K shaft seal that follows DIN 748 and DIN 6885 T1. Rotor length code 4 keeps the overall size compact for installations where space is limited. The IEC flange mount, O-ring sealing, smooth surface finish, and stainless housing support hygienic use during caustic wash cycles.
