Stainless steel servos

Baldor has introduced a new family of all-stainless-steel servomotors, providing protection for demanding automation applications in clean environments.

Baldor has introduced a new family of all-stainless-steel servomotors, providing protection for demanding automation applications in clean environments such as bio-pharm and food packaging and processing lines, or hostile operating situations such as inside machine tools.

The new 25-strong family – the Baldor SSBSM Series – is designed to withstand high-pressure washdown environments. Among the protection features incorporated is a 304 stainless steel housing that is protected to IP67 standards and which will withstand cleaning using caustic materials at pressures up to 103bar (1500PSI).

Other advanced protection features include an FDA (US Food and Drugs Administration) shaft seal to comply with food industry and BISSC (US Baking Industry Sanitation Standards Committee) standards, a potted stator for environmental protection and high voltage protection and an internal thermal switch to safeguard against overheating.

The new servos also use Exxon Polyrex EX Polyurea grease lubrication for extended life and sport a laser etched nameplate to ensure that there are no areas for process media and bacteria to cling to.

They are available in five frame sizes with continuous torques from 0.45 to 32Nm (3.9 to 280 lb-in), and peak torques ranging from three to four times the continuous duty ratings. The motors may also be specified with standard or low inertias to help OEMs to optimise machine performance for specific applications and loads.

Baldor offers compatible drives to accompany the new motors, as well as a choice of motion controllers in either PCB or packaged and ready-to-use forms.
