Abstract:
1. A pump motor assembly operable to provide driving power to a fluid pump, said pump motor assembly comprising: a rotor rotatable about a rotational axis; a stator spaced radially from the rotor; a case at least substantially housing the rotor and the stator; and a control assembly mounted to the case and operable to control motor operation based upon at least one input, said control assembly including a display on which information regarding motor operation is displayed, said control assembly including a cover disposed in a covering relationship relative to the display, said cover including a substantially transparent window section in general alignment with the display, said control assembly including a substantially transparent filler plate underlying the window section in an interposed relationship between the display and the cover, with the filler plate contacting the window section so as to at least substantially eliminate any air gap along an underside of the window section, thereby permitting the display to be visible through the window section while reducing the risk of condensation buildup along the underside of the window section, said at least one input including a manually operable switch, said switch and said display cooperatively presenting a user interface of the control assembly so as to provide user-selected control of the motor, and thereby the pump, at the motor, said switch comprising a manually depressible button underlying the cover, said cover comprising a flexible membrane so as to permit button operation from outside the cover, said control assembly including a protective lid shiftable into and out of a closed position, in which the lid is substantially superimposed over the cover.
