Product Description:
The AKMH33H-ACKNCA1K is a hygienic stainless-steel washdown motor produced by Kollmorgen and supplied within the AKMH Stainless Servomotors series. Designed for direct connection to an AKD servo drive through its pre-assembled cable, the unit provides rotary motion to conveyors, augers, and other axes located inside sanitary process zones. Its sealed 1.4404 housing, flange-mount IEC interface, and IP69K shaft seal allow the motor to withstand high-pressure washdown while eliminating external crevices that could trap contaminants. This layout supports installation in food, beverage, and pharmaceutical equipment where frequent cleaning is part of normal operation.
During continuous operation, the motor can deliver 2.60 Nm of stall torque while drawing 5.00 Arms. The back electromotive force generated at rated speed is 33.4 Vrms/kRPM, a value the drive uses to establish voltage limits for field-oriented control. Because the enclosure meets IP69K, it endures high-temperature, high-pressure water jets used for cleaning. The shaft, flange, and cylindrical body are machined from 1.4404 (316L) Stainless Steel, which helps resist corrosion when exposed to caustic detergents and repeated washdown cycles. This operating range suits motion tasks that must continue reliably in enclosed process areas where moisture and cleaning chemicals are regularly present.
Motor dynamics are shaped by a torque constant of 0.53 Nm/A, so each ampere of incremental current produces slightly more than half a newton-meter of torque. Current rise is filtered by the phase inductance of 4.1 mH, which moderates switching ripple and supports winding protection during changing load demands. The winding system has a thermal time constant of 40 min, which indicates a gradual heat buildup during sustained operation. Position feedback is handled by the integrated Smart Feedback Device (SFD3) encoder, delivering 11-bit resolution without external couplers. Combined with the motor's low rotor inertia, these characteristics support rapid acceleration and stable servo response on washdown machinery.
