Servomotor series is characterised by its high dynamic response and its compact design.
Siemens Automation and Drives (A and D) has launched a new compact 1FT7 servomotor for high-performance applications in machine tools and production machinery.
The servomotor series is characterised by its high dynamic response and its compact design.
With the new servomotor, even the self-cooled version has an overload withstand capability of four times the standstill torque and the speed range goes to 6000rev/min.
In field weakening mode, it can be additionally expanded with inverters of the Sinamics S120 series.
Productivity is therefore increased as machines can now be used over an expanded load range.
The service life of the encoder is also significantly increased thanks to a newly developed coupling which protects the incremental encoders against shock loads on the motor shaft.
The cross profile of the new motors also enables simple installation even from the rear, and a rotatable, fast locking connector simplifies connection and cable laying in all installation positions.
This helps reduce both installation and service times.
Compared with its predecessor series, the 1FT6, the length of the 1FT7 has been reduced by one-third.
However, both models are compatible with regard to installation, connections and characteristic curves so there is no problem in replacing the predecessor model with the 1FT7.
