Product Description:
The AKMH43E-BKV2CA3K is a hygienic stainless steel washdown motor built by Kollmorgen for the AKMH Stainless Servomotors series. It is designed to drive axes in food, beverage, and pharmaceutical machinery where equipment must tolerate continuous high-pressure sanitation. Its hygienic housing supports use in automated processing areas that require frequent cleaning with steam, water, or detergent.
A protection rating of IP69K allows the housing to withstand close-range steam and detergent jets without moisture intrusion. The enclosure is machined from 1.4404 (316L) stainless steel, so corrosive cleaners do not degrade the surface. Power-off shaft retention is provided by a 24 V DC holding brake, preventing load drift on vertical or indexing stations. Position feedback is supplied through a Smart Feedback Device (SFD3) encoder with an 11-bit native resolution, allowing the servo drive to regulate position and speed accurately. The motor includes a 3-meter cable terminated with an IP69 SpeedTec connector, so an additional junction box is not required inside the washdown zone. Winding type E matches the electrical characteristics expected by compatible Kollmorgen drives. This arrangement also keeps removable electrical connections away from areas exposed to routine sanitation.
The mounting interface has a flange outside diameter of 114 mm and a pilot diameter of 80 mm. Both dimensions support NEMA flange mounting for direct attachment to gearheads or machine plates. Torque is transmitted through a 19 mm shaft with an open keyway that simplifies coupling installation. The surface roughness is less than 0.8 µm, limiting areas where residue and bacteria can adhere during operation. Frame size AKMH4 and rotor length 3 establish the magnetic stack depth for this model. An FDA-approved O-ring seated in the flange groove and an IP69K shaft seal form the primary fluid barrier. The shaft seal uses mineral-filled PTFE to protect the bearing set and retain sealing performance after repeated thermal shocks.
