Abstract
A pump assembly and a method for sensing rotary motion of the pump therein are disclosed. The pump assembly includes a pump, a controller, and an optional driven electric motor. The components may be axially aligned and mounted relative to one another. The controller includes a circuit board that is oriented in an axial direction of the pump assembly so that it faces in a radial direction. A 3D rotary sensor is mounted on the circuit board and is designed to detect motion parallel to its front face and motion in a plane perpendicular to its front face, including rotary motion of the pump, for output to the controller. The controller is configured to control the pump via controlling the drive shaft of the motor or pump.
