The fully digital control of the SINAMICS S120 drive system and the encoder technology of the 1FT6 motors fulfill the highest demands in terms of dynamic performance, speed setting range, and rotational and positioning accuracy. 1FT6 motors are available with natural cooling, forced ventilation or also with water cooling. With the natural cooling method, heat is dissipated through the surface of the motor, whereas with th...
