Compact design for new servo motor series

Siemens Industry Automation & Drive Technologiesvisit website

 

Siemens Automation and Drives (A&D) is presenting the 1FT7 servo motor for high-performance applications in machine tools and production machinery at the SPS/IPC/Drives trade fair. This servo motor series is characterised by its high dynamic response and its compact design.

With the new servo motor, even the self-cooled version has an overload withstand capability of four times the standstill torque, with the speed ranging to 6000rpm. In field weakening mode, it can be additionally expanded with Sinamics S120 series inverters. Machines can therefore be used over an expanded load range and are consequently more productive.

A newly developed encoder coupling protects the incremental encoders against shock loads on the motor shaft. This significantly increases the expected service life of the encoder. The physical profile of the new motors enables simple installation even from the rear. A rotatable connector with fast locking simplifies connection and cable laying in all installation positions. This helps to reduce installation and service times.

Compared to its predecessor, the 1FT6 series, the length of the 1FT7 has been reduced by almost one-third. At the same time, both models are compatible with regard to installation, connections and characteristic curves, ensuring a straightforward upgrade.
