  • METHOD, SYSTEM AND APPARATUS FOR AN EFFICIENT DESIGN AND OPERATION OF A PUMP MOTOR
    Publication number: 20090151801
    Abstract: A method of operating a controller for a pool pump motor includes the steps of setting an operating mode for the pool pump motor, setting a torque value for the pool pump motor corresponding to the operating mode, setting a high operating threshold and a low operating threshold corresponding to the torque value, operating the pool pump motor in a constant torque mode using the torque value, monitoring an operating parameter of the pool pump motor corresponding to a load on the pool pump motor, discontinuing operating the pool pump motor when the operating parameter is higher than the high operating threshold or lower than the low operating threshold and signaling a pool pump motor fault upon the discontinuing operating the pool pump motor. The operating parameter of the pool pump motor is RPM or current supplied to the pool pump motor. Additionally disclosed are energy efficient pool hydraulic design techniques that increase the energy efficiency of hydraulic systems.
