Product Description

2.5 Drives for applications in hygienic areas

High demands are placed on hygiene both for the production of beverages and food and

in the chemical and pharmaceutical industries. Often, regulations stipulate a completely

germ-free environment. The drive solutions used in the past made it very hard to clean

the production system as thoroughly as required. Standard motors usually have cooling

fins and fans. Dirt can collect in these components where it cannot be fully removed due

to problems of accessibility. This can lead to a build up of germs!

SEW-EURODRIVE solves this problem by using special gearmotors in hygienic design.

Thanks to their smooth surface, the helical, parallel shaft, helical-bevel or helical-worm

gearmotors in hygienic design are easy to clean and prevent a build up of germs or

bacteria on the surface.

The drives for applications in hygienic areas are equipped with special AC motors of the

DAS80 ... DAS100 series. These motors have the following characteristics:

• Motors with a smooth surface without cooling fins

• Pure convection cooling (without fan)

• Rated power in S1 mode 0.25 kW ... 1.5 kW

• Motor enclosure IP66 as standard (brake motors IP65)

• Electrical connection via plug connector in enclosure IP66

• Motor to be mounted directly on standard R, F, K and S gear units

• with KS corrosion protection

• Surface protection coating to protect against chemicals and solvents

• All surface recesses sprayed with elastic rubber compound as an option

• Optional with brake for 110 ... 500 V

• Optional with encoder for speed-controlled inverter operation

Gearmotors in hygienic design from SEW-EURODRIVE also create the perfect

conditions in your production system for the hygienic production and packaging of food

and beverages.
