Always providing the right spin at precisely the right time

Complete torque motors are permanent magnet AC synchronous motors that are used as a replacement for hydraulic and conventional electric drives, consisting of electric motor and gearbox or belts. They are especially suited for use as direct drives in applications with a torque range of 100 Nm to 7.000 Nm at speeds of 50 to 1.800 rpm. 
Complete torque motors are delivered factory-assembled.

The extremely compact, water-cooled SIMOTICS T-1FW3 complete torque motors are flanged to the machine using torque arms specifically developed for the purpose. An optional clamping element makes it easier to couple the rotor to the machine shaft. The pre-installed mounting set includes the torque arm, clamping element and centering sleeve (only for hollow shafts) – making it simple and safe to establish a connection to the motor. This creates a perfectly stiff drive train that can be optimally controlled.

Built-in torque motors are liquid-cooled resp. self-cooled high-pole permanent excited three-phase synchronous motors with hollow-shaft rotor. The motors are supplied as built-in components. For a complete drive unit, a bearing and an encoder system are required additionally.

For SIMOTICS T-1FW6 built-in torque motors, stator and rotor are supplied as

components and are directly integrated in the machine itself. They are available

with jacket as well as with integrated cooling. Further, the motors operate

without any mechanical transmission elements – e.g. coupling and gearbox

– and require significantly less space than conventional drives. The compact

design and low number of installed parts reduce the number of interfaces,

maintenance costs and stock inventory costs – thus minimizing machine

failures.
