Abstract: An integrated direct drive motor system for industrial use includes an outer rotor motor axially aligned with, and coupled to, a rotating drum, with no transmission or clutch mechanism between the two so that the drum is effectively an extension of the outer rotor of the motor. An adapter coupler attaches to the motor and the drum to allow the motor to directly drive the drum. In one exemplary embodiment, a flexible curtain is spooled vertically by the drum to control an industrial high-speed roll-up door. In another exemplary embodiment, an endless-loop belt is driven by a horizontally-oriented drum to control an industrial conveyor system. Various embodiments of the integrated direct drive motor system and various method of operation are disclosed.
