New High-Performance, Compact Servo Motors for Demanding Motion Control

New Siemens 1FT7 servo motors, shown (l to r) in forced ventilation, water-cooled and air-cooled styles

Siemens introduces the 1FT7, a line of high-performance servo motors for such demanding motion control applications as machine tool CNC interpolation, production machine indexing control and more.  Their use results in higher dynamic response, due to a 30% shorter design and 4x overload capacity versus 3x on the predecessor family of servos.  Less downtime also results from the rigid vibration-insulated encoder mounting, which also enables the OEM or end user to exchange the encoder in the field in less than five minutes, without encoder alignment.

Design engineers have a choice in selecting this servo, as it is available in air-cooled, forced ventilation and water-cooled designs.  The water-cooled design of the 1FT7 is provided with stainless steel piping in the stator.

Start-up and commissioning personnel will appreciate the Siemens electronic nameplate and digital encoder interface on this new servo, DRIVE CLiQ, as it simplifies start-up or replacement by not requiring all electronic data to be entered, as the DRIVE CLiQ cable recognizes all drive system components.  With this feature, these motors become essentially plug-n-play devices.  The drive recognizes the motor automatically and optimizes the parameterization accordingly.  This digital encoder interface further allows users to route all their different encoder types along one signal cable.

High-resolution encoders, currently 22 bit, enable these servos to become highly precise motion control system components and these new high-dynamic 1FT7 motors also feature very low rotor inertia, thereby making them practical in applications where it was previously impossible to drive a servo.  Such applications include sorters in the printing industry, which previously required mechanical cams but can now utilize electronic cams for better energy efficiency and less wear.
