Product Description:
The AKMH33C-ACKNCA1K is a servo motor built by Kollmorgen and supplied within the AKMH Stainless Servomotors series. It is classified as a hygienic stainless steel washdown motor and is intended to deliver closed-loop torque and speed control in industrial automation zones that undergo frequent high-pressure cleaning. Its washdown-focused design suits food, beverage, and similar processing equipment where exposed motor surfaces must be easy to clean. In these applications, stable feedback and controlled torque output support repeatable motion during conveying, indexing, and other continuous machine tasks.
The AKMH3 frame size uses IEC flange mounting. A flange diameter of 89 mm and a 60 mm pilot locate the housing precisely, while the IM B5 style keeps all fasteners on the front. An FDA-approved O-ring at the flange joint and surface roughness below 0.8 µm support hygienic requirements, and the body is made from 1.4404 stainless steel. The shaft carries a closed keyway that follows DIN 748 and DIN 6885 T1, and the seal material is mineral-filled PTFE. A pre-assembled cable for AKD drives simplifies wiring, and the encoder uses Smart Feedback Device technology to deliver 11 bit position data. Electrical performance begins with a standstill current of 1.37 A that yields 2.46 Nm. The motor can supply 9.94 Nm when 5.9 A is delivered, with a torque gradient of 1.83 Nm/A. Rotor inertia is 0.85 kg·cm², rotor length code 3 is used, winding type C is installed, and the motor comes without a brake.
The housing and seal set achieve IP69K ingress protection, allowing exposure to high-pressure washdown. Stator windings accept a DC link of 640 VDC, giving the connected AKD amplifier suitable voltage headroom for rapid acceleration. Mechanical power is transferred through a 14 mm diameter shaft. Electrical loss is governed by a winding resistance of 26.6 Ω, which supports accurate thermal modeling under load. These operating characteristics suit systems that must maintain controlled motion while also tolerating aggressive cleaning routines in exposed production areas.
