The new servomotors are available in a range of power ratings, from 0.45–2kW (0.60–2.68 hp) with torque from 3.1–14 Nm (2.28–10.32 ft-lbs.). Made with housings of 1.4404 (AISI 316/316L) stainless steel, EPDM seals and bearing grease with NSF H1 approval, the company said the new servomotors are resistant to corrosion and acidic chemicals found in the process industries. This degree of protection is in accordance with IP66/67 standards on the entire motor, with IP69k (30-bar) protection provided on the motor housing.
Siemens said added features include high dynamics due to low inherent inertia plus high overload capacity for use in pick-and-place applications, as well as precise movement of heavy loads. One cable connection is provided for easy installation and cleaning. The standard absolute encoder is 22-bit multi-turn.
The SIMOTICS S-1FS2 family of motors is suitable for clean-in-place (CIP) processes and for use with all commercially available cleaning agents used with washdown motors.
The motors are especially designed for the 3-A (U.S.) and EHEDG (Euro) requirements of the food and beverage industries.
Options include a holding brake, stainless steel shaft with or without feather key, cable tail for direct drive connection and a MOTION CONNECT coupling. MOTION CONNECT is the Siemens fully assembled power and signal cable design for use on production machinery of many types.
SIMOTICS S-1FS2 is compatible with the SINAMICS S210 drive system.
