Title: Optimal design of hybrid magnet in maglev system with both permanent and electro magnets

Abstract

A magnetic levitation system with both permanent magnets and electromagnets has less power loss than a conventional attractive-type system. In this paper, the authors propose an analysis procedure of the hybrid magnet in the experimental levitation system. First, they make a two-dimensional analysis of the hybrid magnet. Though the vector potential A method is often adopted to solve magnetic problems, they propose the magnetic field intensity H method. Second, utilizing the sequential quadratic programming method, they attempt to optimize the arrangement of permanent magnets, which have the maximum guidance force. Finally, they investigate the responses of the experimental magnet levitation system by simulations.

  • The successful design of a near-zero-power-loss Maglev system with permanent and electro magnets depends chiefly on its low power consumption even with frequent regulation. This paper presents a systematic approach for designing such a system. The lift force is calculated by the ''variable flux permeance'' method, and detailed investigation of the regulation power consumption is given. Several practical considerations, such as minimal mechanical clearance and maximal magnetomotive force of the winding, together with the objective of minimizing total magnet weight and regulation power consumption are formulated into a nonlinearly constrained optimization problem, and is solved by the sequentially unconstrained minimizationmore » technique. The designs show that, at 8 mm air gap and 5 kgw lift force, the lift force to permanent-magnet weight ratio is approximately 100, and when the lift force is 500 kgw at 10 mm, the ratio is approaching 110. This confirms the superior performance of the new levitation system in both small and large scale applications.« less
  • In this x-ray/MR hybrid system an x-ray flat panel detector is placed under the patient cradle, close to the MR volume of interest (VOI), where the magnetic field strength is {approx}0.5 T. Immersed in this strong field, several electronic components inside the detector become magnetized and create an additional magnetic field that is superimposed on the original field of the MR scanner. Even after linear shimming, the field homogeneity of the MR scanner remains disrupted by the detector. The authors characterize the field due to the detector with the field of two magnetic dipoles and further show that two setsmore » of permanent magnets (NdFeB) can withstand the main magnetic field and compensate for the nonlinear components of the additional field. The ideal number of magnets and their locations are calculated based on a field map measured with the detector in place. Experimental results demonstrate great promise for this technique, which may be useful in many settings where devices with magnetic components need to be placed inside or close to an MR scanner.« less
  • A permanent magnet electron cyclotron resonance microwave plasma source has been coupled to a copper sputter target to produce ionized copper fluxes for submicron integrated circuit metallization. A custom launcher assembly allows the use of microwave powers up to 5 kW in a metal deposition environment to produce plasma densities {approx_gt}10{sup 12} cm{sup {minus}3}, well above the cutoff density at 2.45 GHz of {approximately}1{times}10{sup 11} cm{sup {minus}3}. Six hundred nm, 1.1:1 aspect ratio features have been filled with copper, and 250 nm, 6:1 aspect ratio features have been successfully lined. Copper ionization fractions for the conditions used for lining andmore » filling, determined by a combination of Langmuir probe measurements and optical emission spectroscopy, are between 10{percent} and 35{percent}. {copyright} {ital 1996 American Vacuum Society}« less
  • This paper describes a current vector control method of permanent magnet synchronous motors (PM motors) for high torque operation. In this control method, the current phase angle is controlled according to load conditions in order to use the reluctance torque effectively. Several characteristics such as torque, efficiency, power capability and so on are greatly improved by this control on comparison with the conventional control method. The performance characteristics are greatly affected by the motor parameters which depend on the rotor configurations and permanent magnet geometries. The available maximum torque and power capability are also examined for the several types ofmore » PM motor considering the inverter capacity. The tendency toward magnetic saturation and demagnetization of permanent magnet are also examined.« less
