Product Description:
The AKMH42C-ACKNCA1K is a hygienic stainless-steel washdown motor from Kollmorgen's AKMH Stainless Servomotors series. As a hygienic servo actuator, it delivers closed-loop torque to conveyors, indexers, and pick-and-place heads in sanitary automation cells that require daily high-pressure cleaning. Its stainless-steel washdown construction supports repeated cleaning while maintaining controlled servo operation in exposed processing areas. This design is intended for equipment with exposed product zones, where smooth surfaces and washdown-ready components are preferred. Position feedback is supplied by an SFD3 smart encoder with 11-bit resolution for tight loop control.
Continuous performance is rated at 3.15 Nm of stall torque at 1.41 Arms and increases to a peak of 11.0 Nm when up to 5.60 Arms is available from the drive. The stator windings accept 640 V DC on the bus, and the magnetic circuit permits speeds up to 6000 rpm for fast indexing. A line-to-line inductance of 97.4 mH and resistance of 27.5 Ω shape current response, while rotor inertia of 1.45 kg-cm² and rotor length code 2 influence acceleration behavior. These electrical characteristics help the drive regulate current cleanly during repeated starts, stops, and rapid indexing moves. Winding type C, a mineral-filled PTFE cable jacket, and a one-meter pre-assembled cable support connection to compatible AKD drives through the designated interface.
The motor has IP69K enclosure protection, a 114 mm IEC flange with FDA-approved O-ring sealing, and a 1.4404 stainless housing polished below 0.8 µm Ra to resist biofilm. The AKMH4 frame uses an 80 mm pilot, IM B5 standard style, and IEC flange mounting. The flange and pilot dimensions support secure mounting on compatible machine plates. A closed-keyway shaft measures 19 mm in diameter, is protected by an IP69K shaft seal, and complies with DIN 748 and DIN 6885 T1. Because the motor has no holding brake, static positioning relies on drive torque. Surface protection is supported by the shaft seal and material selection, which withstand caustic or acidic cleaning solutions.
