Food-grade servo motors from Rockwell Automation offer high-torque, efficiency

Electric motor manufacturers are increasingly catering to the tough environment of food/beverage packaging and handling. Here’s a recent example, if you’re looking for parallels that could be appropriate to your application.


Rockwell Automation’s food-grade servo motors come with continuous stall torque of 1.6 to 19.4 Nm (14-173 lb-in.).

Electric motor manufacturers are increasingly catering to the tough environment of food/beverage packaging and handling. Here’s a recent example, if you’re looking for parallels that could be appropriate to your application.

Rockwell Automation has introduced Allen-Bradley MP-Series Food Grade Motors (MPF Motors) designed with advanced sealing methods (IP66 and 67) and noncorrosive materials—such as food-grade fasteners, bearing grease, and epoxy paint—to guard against liquid contamination and reduce corrosion from exposure to cleaning solutions and food by-products.

These food-grade motors reportedly provide excellent torque-to-inertia ratio for rapid acceleration. Food and beverage OEMs can translate this performance into machines with improved product throughput, flexibility, and precision. MPF motors, an expansion of Rockwell’s MP-Series family, include a shaft seal with hardened wear sleeve for long life. Another feature is a special IP67-rated connector that can be rotated 180 degrees without use of tools to allow optimum positioning of the motor without risking seal integrity.

For applications requiring high-end accuracy and precision, MP-Series motors offer optional multi-turn absolute feedback, which can position the servo system to within one millionth of a revolution. Absolute encoder feedback also eliminates time-consuming homing routines.

MPF Motors are a part of Kinetix Integrated Motion solution, for more information contact Rockwell Automation Response Center at +1 800/223-5354, ext 1647.
