BAUMULLER – Update for servomotor with hygienic design

Baumüller revises its stainless steel servo motor series HYG1 for processes with strict hygiene requirements

The Nuremberg automation and drive specialist Baumüller has revised its servo motor series for aggressive environments and for industries with very high hygiene, cleanliness and corrosion protection standards and increases flexibility for linking to its customers’ machines.

In addition to the B14 flange option available until now, the B5 option is now also offered for connecting the HYG1 to gearing. With this new variant, the motor can now also be attached to stainless steel gearings, which facilitates its use in demanding applications such as in the food industry.

Fast cleaning and minimum standstill times

Machines in food processing, beverage filling, and the pharmaceutical and packaging industries must be quick and easy to clean. At the same time, bacterial colonies must never grow as a result of accumulated dirt or cleaning agents. Baumüller meets this requirement with the HYG1. Classified
under the IP69K protection class, it is quick and easy to clean, thereby minimizing downtimes.

Single cable solutions ensure little wiring effort

The compact servo motor has a round stainless steel housing and, thanks to the single cable solution which connects the main connection and encoder cable without further connectors, requires very little wiring effort. All rough edges were eliminated in the HYG1 in order to meet the highest demands on hygiene and durability, even in aggressive environments. The corrugated design of the servo motor maximizes the surface area and therefore the self-cooling capacity of the motor. This makes the power density of the HYG1 especially high in a small installation space.

The HYG1 motor series is currently available in size 36 and in two different overall lengths with an output of up to 1160 W and a speed of 1000 to 4000 min-1.
