摘要： The present invention is directed to a load bearing direct-drive system for driving a fan in a cooling system such as a wet-cooling tower, air-cooled heat exchanger, HVAC system, hybrid cooling tower, mechanical tower or chiller system. The present invention includes a variable process control system that is based on the integration of key features and characteristics such as tower thermal performance, fan speed and airflow, motor torque, fan pitch, fan speed, fan aerodynamic properties, and pump flow. The variable process control system processes feedback signals from multiple locations in order to control a high torque, low variable speed, load bearing motor to drive the fan.

摘要： An electric machine has a housing which has an interior space and an interior wall extending about the interior space, and a stator assembly disposed within the interior space and attached to the interior wall. The electric machine includes a rotor within the interior space and located radially inward from the stator. The rotor and stator define a gap there between and cooperate to produce flux. The rotor comprises a hollow cylindrical member having an interior region, an interior wall extending about the interior region and an exterior surface. The rotor includes magnets attached to the exterior surface and a rotor shaft support structure disposed within the interior region of the hollow cylindrical member and attached to the interior wall of the hollow cylindrical member. A rotor shaft is attached to the rotor shaft support structure. The electric machine further comprises bearings to locate and support the rotor shaft relative to the housing.
