High-inertia servomotor

August 30, 2010

Siemens Industry Inc. has introduced the 1FK7-HI high-inertia servomotor. The high rotor inertia makes the control response suitable for high- and variable-load inertia applications, including the feed and auxiliary axes on machine tools, as well as winders and unwinders on converting, packaging, and printing equipment.

The self-cooled servomotors provide stall torque from 3 to 20 Nm and are offered in IP64 or IP65 with IP67 flange degree of protection, with selectable options for plain or keyed shaft, holding brake, 22-bit incremental or absolute encoders, and 18 colors.

A mechanical decoupler between the motor and encoder shaft protects the encoder from mechanical vibrations. If the encoder needs to be exchanged, the device automatically aligns the encoder signal to the rotor pole position, enabling feedbacks to be changed in the field in less than five minutes, according to the manufacturer.

The servomotors also feature the Drive-Cliq® serial bus and electronic nameplate recognition, allowing virtual plug-and-play operation when paired to the Sinamics® S drive platform. All servomotors in this new line are configured to interface with Siemens Sinumerik® CNC technology.
