IV. Core Product Characteristics

IP67 Full Waterproof Protection

Complete machine sealing design, capable of withstanding 10bar high-pressure water flushing, steam cleaning, acid and alkali environments, shaft end uses double lip seal, completely preventing liquid and dust intrusion, meeting CIP/SIP cleaning requirements for food and pharmaceutical industries Kollmorgen.

All stainless steel corrosion-resistant structure Key components (such as shafts, flanges, screws) are made of 316 stainless steel. The base is coated with 2-K corrosion-resistant coating, which is resistant to seawater, food acids, and cleaning agent corrosion. The service life is more than three times that of standard motors. Kollmorgen.

Food-grade safety certification

It uses NSF H1 food-grade lubricant, complies with FDA 21 CFR 175.300 standards, and can be directly used in food, pharmaceutical, and cosmetic production equipment. There is no risk of safety contamination. Kollmorgen.

High torque density and stability

The electromagnetic design is optimized. The 108mm flange outputs 11.4Nm continuous torque. The low tooth-slot effect design ensures no jitter at low speeds and low noise at high speeds. The positioning accuracy reaches ±5 arc seconds.

Wide voltage adaptation and global universality

R-class windings are compatible with 240VAC/320VDC bus voltages, compatible with global industrial power grids, and can directly match Kollmorgen's AKD-P01206, AKD-P02406, etc. drives.

Waterproof dedicated connection system

Straight M23 waterproof connector + special sealed cable, 360° fully shielded, IP67 sealed. The wiring is flexible and the connection is reliable, suitable for humid, water-rich, and dusty environments. Kollmorgen.
