Siemens Introduces Three-Week Lead Time on Servomotors

Print Print this article | Send to Colleague

In response to increased market needs and always seeking to exceed customer expectations, Siemens Industry Inc., Washington, D.C., USA, has announced a further reduction in lead times for Generation II of its Simotics® 1FK7 servomotors. Configurable to suit a wide variety of applications, this line features seven shaft heights, Quick-Connect power connectors, and 20- and 24-bit field replaceable encoders in 10 styles, all combined with a three-week lead time, beginning January 1. The new Siemens service applies to all motor models in the line, when ordered without gear box.  

The 1FK7 Generation II servomotors offer 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 and the heat is dissipated through the motor surface. With 10 styles of field-replaceable encoders, the 1FK7 Generation II servomotors provide easy maintenance in the field, with reduced downtime and operating cost savings. A 10% improvement in continuous (S-1) power is achieved, since the encoders are mechanically and thermally decoupled from the motor. The mechanical decoupling also means the encoder is more resistant to vibration conditions on the machine. In addition, there is no need for battery back-up on the absolute encoders.  

The 1FK7 Generation II servomotors also provide users with 3x overload, 2.5% torque ripple, cross profiling for easier mounting, Siemens Drive-Cliq interface for easier field commissioning and unit recognition with the Siemens Sinamics S120 drive family, plain shaft or keyway design, three IP ratings, and are supplied with or without holding brake.
