With a total of 4 patents to his name, Cain's work focuses on enhancing the efficiency and functionality of motor pumps and turbines.
Latest Patents
One of Sean A. Cain's latest patents is for an "Integral motor pump or turbine with sensorless monitoring of axial bearing wear." This innovative design allows for the monitoring of axial bearing wear without the use of sensors. Instead, it estimates the axial rotor-stator gap based on the known relationship between back EMF and the impeller rotation rate. This method can be applied to both integral motor pumps (IMPs) and integral motor turbines (IMTs). The system can halt operation if the estimated rotor-stator gap falls outside a specified range, ensuring safety and reliability.
Another notable patent is for an "Efficient system for pumping low-density liquids." This system utilizes a series of integrated motor/pump modules (IMPs) to pump low-density liquids, such as liquid hydrogen. Each IMP is equipped with a single impeller, and a controller adjusts their speeds to achieve the desired head while maintaining critical NPSH levels. This innovative approach allows for efficient pumping while ensuring that each module operates within safe parameters.
