MTC Series The method of construction as a self-cooled, external-rotor machine facilitates direct, torsion-resistant coupling to the load. Using the integrated absolute transmitter system it is possible to move to arbitrary positions precisely and in a highly dynamic fashion. The MTC motor is particularly well suited to act as a swivel drive for productronics, for circular indexing tables or for handling tasks of all types. The hollow shaft allows cables, hoses, laser beams or mechanical connections, for example, to be fed through.
