To solve the problem caused by the heavily axial gravity load of the rotor and main shaft of the vertical hydraulic generators, a superconducting induction magnetic levitation device is proposed in this paper. AC superconducting windings are implemented to increase the levitation force. The inductive eddy magnetic field acts back on the primary field, and the levitation force and rotation torque will...
To solve the problem caused by the heavily axial gravity load of the rotor and main shaft of the hydraulic generators, a superconducting induction magnetic levitation device is proposed for hydraulic generator system. AC superconducting windings are implemented to increase the levitation force. The basic structure and principle are introduced. According to the calculated magnetic field distribution,...
Optical tweezers have become an efficient tool to trap microscopic and nanoscopic objects and manipulate their mechanical motion via optical forces and torques [1–3]. In this talk we discuss our recent experimental and theoretical works on trapping and manipulation of micrometer-size Janus particle with half surface of polystyrene particle coated with nanometer-thick gold thin film in various optical...
