Kits of STK roto-stator units for direct drive are available in 2 ranges with the same technology but different windings and wiring and electro-mechanical data customized according to the applications: STK torque motors and STK alternators.

 ST torque motors for direct drive with rare earth magnets are the up-to-date version of FC motors with ferrite magnets.  The RESFC range of hollow shaft precision resolvers are essential complements to torque motors when the user needs to address applications without the restrictive environmental conditions of most encoders. The 136OEP motors are characterized by exceptionally high power-to-weight up to t 6000 rpm. Finally, while our torque motors are used successfully worldwide with most electronic drives on the market, we also offer a range of single-axis drives, DS 2020 models, to control our motors.
