Product Description:

The AKMH32C-ACKNCA1K is a hygienic stainless steel washdown servo motor built by Kollmorgen as part of the AKMH Stainless Servomotors series. Designed for direct integration into wet-area packaging, filling, and clean-in-place lines, the motor supplies torque to automation axes while eliminating external protective housings. Its smooth 316L enclosure, food-grade seals, and pre-assembled drive cable allow rapid installation of precision motion in environments that demand frequent high-pressure sanitation.

The motor delivers a continuous stall torque of 1.72 N·m at a continuous stall current of 1.30 A, which are the limits for continuous duty. The electromagnetic design produces 1.32 N·m per ampere, so rated current aligns with this constant. During acceleration, torque rises to 6.92 N·m while current can reach 5.8 A, and the AKD servo amplifier must accommodate these peaks. Winding resistance of 23.8 Ω and inductance of 46.5 mH shape the current loop, and the C-type winding is sized for bus voltages up to 640 VDC. Position feedback comes from an SFD3 encoder that outputs 11-bit rotor angle data.

With a motor length of 166.5 mm, frame size AKMH3, and standard IM B5 flange mounting, the unit connects to machinery through an 89 mm flange seated on a 60 mm pilot. The shaft diameter of 14 mm with a closed keyway follows DIN 748 / DIN 6885 T1, and the shaft seal blocks washdown liquid. The housing is machined from 1.4404 (316L) Stainless Steel with surface roughness below 0.8 µm, while an FDA-approved O-ring secures the joint. Rotor inertia is 0.59 kg·cm², and rotor length code 2 matches the selected inertia. A one-meter mineral-filled PTFE cable, terminated for AKD drives, exits through the flange to maintain the IP69K rating. There is no integrated holding brake, so static torque must be provided electrically.
