The Van der Graaf new Intelligent Drum Motor (IDM) technology delivers an exceptionally high continuous torque profile, full speed and indexing control and significant energy efficiency gains over traditional induction motors. Because the magnetic field of the rotor does not have to be magnetically induced, efficiency gains of up to 70% can be achieved in both no load and fully loaded conditions compared to conventional induction motor and gearbox combinations. This translates into higher torque and horsepower within the same frame size or the ability to use a smaller drum motor with IDM technology in equivalent applications for even further efficiency gains. Without the need for sophisticated and costly servo motors and controllers, the Van der Graaf drum motor with IDM technology comes fully integrated with our compact digital frequency inverter (DFI) boasting full motor indexing speed control and communication, integrated Cat 3 dual channel STO safety mechanism and an all stainless junction box enclosure that meets IP69K ratings for ingress protection.
