Siemens Industry (Elk Grove Village, IL) offers Simotics 1FK7 Generation II servomotors with seven shaft heights, quick-connect power connectors, and 20- and 24-bit field-replaceable encoders. The series offers three inertia versions — standard, high-dynamic for rapid acceleration jobs, and high-inertia for maximum smooth running. The motors are designed for operation without external cooling; heat is dissipated through the motor surface. The encoders are mechanically and thermally decoupled from the motor, making them more resistant to vibration conditions on the machine. The servomotors provide cross-profiling for mounting, Drive-Cliq interface for field commissioning and unit recognition with the Siemens Sinamics S120 drive family, plain shaft or keyway design, and three IP ratings.
