Compact Torque Motors are available with plug-in or solid shaft.
March 3, 2011 -
Series 1FW3 torque motors are available in plug-in shaft version with axis heights of 150, 200, and 280 mm, while solid shaft models are offered for axis heights of 150 and 200 mm. Both versions have rated torque rotational range from 100-7,000 Nm. At height of 280 mm, rated speed range is from 250-600 rpm, suiting motors for use as roller drives. Units are water-cooled and rated power range for all versions is from 3-380 kW.

Siemens Extends Its Range of the 1FW3 Torque Motor Series
In addition to the previously available hollow-shaft motors, the Siemens Drive Technologies Division is now also offering versions with a plug-in shaft and solid shaft in the form of the 1FW3 torque motor series. What's more, the rated speed range has also been increased. As such, the torque motors' field of application now extends to roller drives, cross cutters, winders or silicon cutting etc.
In place of motor-gear assemblies, torque motors are becoming the tool of choice to drive rotary axes, for example, in plastics machinery, the paper industry, textile and printing machinery, as well as in molding technology. In addition to their compact design, they excel due to their precise concentricity, high dynamic response and extremely rugged structure. As a result of their high degree of rigidity, the torque motors are able to directly control manufacturing processes in combination with the Siemens Sinamics S120 drive system. This not only increases the quality of the products manufactured at the plants, but also maximizes productivity and availability of machines.
In addition to the previously available hollow shaft version with axis heights (AH) of 150, 200 and 280 mm, Siemens is now offering motors with plug-in shaft or with a solid shaft. While the version with the plug-in shaft is available for all three axis heights, the solid shaft is offered exclusively for axis heights of 150 and 200 mm. The rated torque rotational range for the three versions will still range from 100 to 7,000 Nm. At an axis height of 280 mm, the rated speed range has been increased from 250 to 600 rpm for all versions. The motors are therefore ideally suited to be used as roller drives. Extending the series with the new mounting versions has greatly facilitated both the mounting and alignment processes, the extent of which depends on the application in question.
Moreover, when it comes to replacing the encoder for the plug-in and solid shaft solution, this is certainly a much more straightforward process. The rated power range for all versions is from 3 to 380 kW. 1FW3 motors are water-cooled. An electronic rating plate and the Drive-Cliq system interface from Siemens pave the way for smooth commissioning. The motors can be dimensioned with ease using the Sinamics Sizer calculation tool.
