Product Description:

The AKMH32H-ACKNCA1K servo motor is produced by Kollmorgen within the AKMH Stainless Servomotors series. It is a hygienic stainless-steel washdown motor intended for direct mounting in food, beverage, or pharmaceutical automation where frequent high-pressure cleaning is required. The housing, machined from 1.4404 (316L) stainless steel with a surface roughness below 0.8 µm, eliminates external crevices, while an IP69K shaft seal blocks water ingress. When paired with an AKD drive through its preassembled feedback and power cable, the unit delivers precise rotary motion on indexing conveyors and sanitary filling axes.

The motor is sealed to IP69K, so it tolerates high-pressure 80 °C washdown streams without additional enclosures. A flange diameter of 89 mm follows IEC flange-mounting conventions and aligns to the B5 style face. The solid shaft diameter of 14 mm with a closed keyway transfers torque to stainless couplings while maintaining cleanability. Internally, a DC link limit of 320 VDC matches AKD drives on 230 V mains, and the winding can absorb surges up to 22.0 A of peak current for rapid acceleration. An FDA-approved O-ring around the flange and the Smart Feedback Device provide a single-cable connection, reducing exposed hardware in wash zones.

It attains a peak torque of 7.21 Nm for short bursts, allowing quick indexing of small load stations, while the continuous standstill torque remains at 1.77 Nm to hold position without a brake. The torque constant is 0.38 Nm/A, which lets the controller predict load response from measured phase current. The electrical model is completed by a phase inductance of 3.53 mH, which shapes current-loop bandwidth and limits conducted noise into the DC bus. This combination supports stable current control during rapid speed changes in sanitary packaging and cutting equipment.
