Abstract
A pump assembly includes a permanent magnet motor having a stator with coil windings, a rotor assembly having a shaft and an impeller attached to the shaft, with the shaft being driven by the stator and the impeller driving fluid through the pump assembly, and a control module having a controller and a user interface. The controller measures characteristics of the stator, the controller determines at least one of the flow rate and the pressure of the fluid moved through the pump assembly based on the characteristics measured, and the user interface is configured to display an output representative of the flow rate. A method of operating a pump includes the steps of measuring at least one operating characteristic of the pump utilizing the controller integrated with the pump, determining a flow characteristic of the pump based on the at least one measured operating characteristic, and displaying the determined flow characteristic on a user interface integrated with the pump.
