Abstract
The present invention is directed to a load bearing direct-drive system and a variable process control system for efficiently managing the operation of fans in a cooling system such as a wet-cooling tower, air-cooled heat exchanger (ACHE), HVAC system, blowers and centrifugal blowers, mechanical towers or chiller systems. In one embodiment, the load bearing direct-drive system comprises a load bearing torque multiplier device having an output rotatable shaft connected to a fan, and a load bearing motor comprising a rotatable shaft that drives the load bearing torque multiplier device.
Claims19
A drive system for rotating a propeller that creates thrust,
- comprising:
- a load-bearing torque multiplier device having a rotatable output shaft connected to the propeller, the torque multiplier device comprising a constant ratio epicyclic traction drive device;
- and
- an electric motor comprising a rotatable shaft that is connected to the constant ratio epicyclic traction drive device so that the rotatable shaft of the motor drives the constant ratio epicyclic traction drive device.
