Beckhoff Unveils Wash-Down Proof Stainless Servo Motor
Stainless steel motor housing is FDA approved.
Burnsville, MN — Beckhoff Automation has introduced the new AM8800 stainless steel servo motor series. The motor supplements the highly dynamic servomotors with single cable technology from the new Beckhoff AM8000 series in a resilient, stainless steel finished version.

The stainless steel motors are implemented completely in a food-grade design; they can be used in extremely harsh or corrosive environments and are particularly suitable for use in the food, chemical or pharmaceutical industries.

All motors in this series need only one motor cable instead of the usual two. The usually necessary feedback cable is eliminated, since the encoder information is transmitted digitally through two cores of the motor cable. The single-cable feedback technology leads to a clear material savings and reduces installation and engineering expenditures.

Technologically, the stainless steel motor series is based on the company's AM8000 motor series. However, it has been supplemented by an all-stainless-steel housing in AISI 316L, which was designed according to FDA guidelines, and a stainless steel motor shaft. The motors are made in three sizes, each with three overall lengths. The power range extends from 1 to 8Nm standstill torque.

In the motor design, corners and edges were avoided; similarly, drill holes and screwed connections were largely dispensed with in order to prevent the accumulation of dirt. The motor flanges are implemented in B5 form and are compatible with the AM8000 series flanges. This helps simplify the conversion of existing plants and machinery.

Power losses have been kept low because of the optimum connection of the stators to the stainless steel housing. This is remarkable, since the motors are implemented without additional cooling and the thermal conductivity of stainless steel is approximately 14 times lower than that of the motor's aluminum housing in its standard version.
