Abstract
A combined pump and motor has a stator mounted for non-rotation in a housing. The stator has windings that create an electromagnetic field in the stator cavity when powered. An upper diffuser and a lower diffuser are mounted for non-rotation in the stator cavity. Annular clearances exist between the upper diffuser and the inner diameter of the stator and between the lower diffuser and the inner diameter of the stator. An impeller between the lower diffuser and the upper diffuser has an array of magnets circumferentially mounted around the impeller that impart rotation to the impeller in response to the electromagnetic field in the stator cavity. The array of magnets has at least one end portion extending into one of the upper and lower diffuser annular clearances.
