New High Inertia Servomotors

At this year's EMO machine tool fair in Milan, Siemens Drive Technologies is showcasing its new High Inertia version of the 1FK7 servomotor for the first time. The motors are used on the feed axes and auxiliary axes of machine tools. The new 1FK7-HI High Inertia servomotor  is characterized by its higher intrinsic moment of inertia. This makes the control response of the motors extremely robust and therefore especially suitable for applications with high and variable load inertia. Drive systems featuring the Sinumerik machine tool control system and motors from the 1FK7 series achieve very high contour precision without the need for time-consuming adaptation of the controller to the machine.
The self-cooled 1FK7-HI servomotors have been designed to be extremely resistant to vibrations and shocks and are available with torques of 3 Nm to 20 Nm. Like all motors of this design, they have an electronic nameplate and the version with the DRIVE-CLIQ serial drive bus is perfectly matched to the Sinamics S120 drive system. The SIZER tool is used for adapting and dimensioning the motors to match the respective application.
