Abstract
A pump motor assembly operable to provide driving power to a fluid pump includes a rotor, a stator, a case housing the rotor and the stator, and a control assembly mounted to the case and operable to control motor operation. The control assembly includes an information display and a cover overlying the display, with a window section in general alignment with the display. The control assembly also includes a filler plate underlying the window section to prevent any air gap along an underside thereof, allowing the display to be visible while reducing the risk of condensation buildup. The control assembly further includes a low voltage housing with the display disposed in a first compartment defined thereby, and a high voltage housing with a high voltage component disposed in a second compartment defined thereby. The low voltage housing includes a thermal and fluid barrier that substantially fluidly separates the first and second compartments to reduce the risk of liquid electrical conduction therebetween and to reduce heat transfer into the low voltage housing.
