Product Description:

The AKMH63L-ACKNCA1K servomotor is built by Kollmorgen within the AKMH Stainless Servomotors series. Classified as a hygienic stainless steel washdown motor, it is intended to drive conveyors, fillers, and other equipment in food, beverage, or pharmaceutical areas that require frequent high-pressure cleaning. The IEC flange mounting interface allows direct installation to gearboxes or machine frames, while its IP69K shaft seal and corrosion-resistant construction help maintain protection when the machine is exposed to caustic solutions.

At the mechanical interface, the motor uses a flange diameter of 186 mm with a 130 mm pilot and follows IM B5 style per DIN 748 and DIN 6885 T1. The housing is machined from 1.4404 (316L) Stainless Steel and polished to a surface roughness below 0.8 µm, and an FDA-approved O-ring seals the flange. The closed-keyway shaft measures 32 mm × 58 mm and is guarded by an IP69K shaft seal. Frame AKMH6, rotor length 3, and rotor inertia of 0.00242 kg·m² support quick acceleration, delivering 14.1 N-m continuous and 39.02 N-m peak stall torque. The motor has a 235 mm body with an outside diameter equal to the flange diameter, and a pre-assembled 1 m cable speeds installation with AKD drives. The enclosure achieves IP69K washdown protection, and position is reported through a Smart Feedback Device (SFD3) encoder.

Electrically, the winding presents 0.96 Ω of DC resistance and an inductance of 7.4 mH, which works with the AKD inverter to regulate current rise. The motor generates 1 N-m of torque for every 0.71 Arms supplied, based on a torque constant of 1.4 N-m/Arms, and develops a back electromotive force of 98.2 Vrms/kRPM. With 10 poles, it sustains 10.2 Arms continuously and tolerates 33.3 Arms at stall for short periods. A mineral-filled PTFE cable jacket withstands aggressive cleaners, and feedback is digitized at 11-bit resolution. The design omits a holding brake to reduce mass, and thermal saturation is delayed by a 62 min time constant, enabling long duty cycles before steady-state temperature is reached.
