High-inertia servomotors for high, variable loads
Siemens Industry Inc. 1FK7 servomotor provides highly robust control response suitable for high- and variable-load inertia applications, such as feed and auxiliary axes on machine tools, and winders and unwinders on converting, packaging and printing equipment.
Siemens Industry Inc. 1FK7 servomotor provides highly robust 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 servomotors are self-cooled and provide stall torque in the 3 Nm to 20 Nm range. They 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, as well as 18 color options.
A mechanical decoupler between the motor and encoder shaft protects the encoder from mechanical vibrations, providing a long service life. In cases where 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. Siemens Drive-Cliq serial bus and electronic nameplate recognition allow virtual plug-n-play operation when paired to the Siemens Sinamics S drive platform. The servomotors are configured to interface with Siemens Sinumerik CNC technology for machine tool applications and the motion controller Simotion for general motion control use.
Siemens Sizer toolbox and compatible 3D CAD model-generating CAD-Creator package help match the motor to suit the application.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
