The torque motors are water-cooled kit motors that have been optimized for high torques of up to 13,800 Nm. They consist of a stator (MST) with three-phase winding and a rotor (MRT) with permanent magnets. Typical areas of operation for these motors are direct drives, such as in rotary tables, swivel axes of machining centers or print works. But they also open up new solutions for innovative mechanical engineering when used in robots, lathes, and plastic, woodworking, and special machines. The "cooling jacket" option for MST stators comprises a cooling jacket with closed cooling circuit, a mounting flange, and an electric connection via terminal box or plug. The back side of the cooling jacket is open, the rotor is connected to the machine's shaft and bearing. This provides the user with the optimum blend of standard solution and high freedom of design when integrating direct drive technology as well as clear cost benefits through reduced design expense and a service-friendly mounting concept.
