This paper describes a newly developed position sensor system. The position sensing system is designed to be combined with the radial permanent magnetic bearing and used for the control of the axial active magnetic bearing. The rotor ring of the radial magnetic bearing is used as field source, which shortens the rotor and saves space for artificial heart design. Linear hall sensor is selected due...
New Intelligent Layered regulating and testing system uses micro-motor source to regulating the size of opened Nozzle in the underground. it can be directly observed the downhole flow changes and judged the regulation purpose of real-time layer on the ground. The essential feature of the new system is that it can accomplish the testing and allocating operation simultaneously. This system doesn't influence...
