Patent ID: 7717683

Claim:
A pump system ( 10 ) comprising: a pump ( 12 ) having a stationary casing ( 14 ) with a frame ( 20 ); a drive motor ( 24 ) with an impeller drive shaft ( 26 ) directly connected to a rotating member of the pump and driving the pump ( 12 ) to pump a fluid or other medium with the rotating member; pump monitoring equipment ( 30 ) for monitoring the pump ( 12 ) and/or the drive motor ( 24 ); and an alternating current (AC) generator ( 42 ) or other suitable electrical generator arranged in relation to the drive motor ( 24 ) and the pump ( 12 ), having a rotary component ( 46 ) and a stationary component ( 48 ), the stationary component ( 48 ) being attached to the frame ( 20 ) and having an annular arrangement of electrically conductive wire coils or windings, the rotary component ( 46 ) being rotatably mounted directly on a section of the impeller drive shaft ( 26 ) for rotating about the axis of the impeller drive shaft ( 26 ) in relation to the stationary component ( 48 ) that does not rotate along with the impeller drive shaft ( 26 ), the alternating current (AC) generator ( 42 ) or other suitable electrical generator being configured for providing power to the pump monitoring equipment ( 30 ).
