摘要
A variable speed drive for fans and pumps. An impeller is connected to a primary motor and an auxiliary motor/generator through a transmission. The transmission includes an epicyclic gearing system. The primary motor is run at constant speed. The auxiliary motor/generator is driven at variable speeds to control the speed of the impeller. The device may be used to retrofit an existing pump or fan system.
