Axial flux segmental rotor flux-switching synchronous motor
2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015A novel three-phase, concentrated winding, axial flux, segmental rotor, flux-switching synchronous motor is presented. The proposed topology has rotor segments made of only iron laminations and operates with flux-switching principle. Compared to existing axial flux permanent magnet (AFPM) topologies, the proposed machine contains reduced amount of ...

Performance improvement in Flux-Switching PM machines using flux diverters
2012 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2012Several schemes for mechanical (as against electrical) flux weakening in permanent-magnet (PM) machines have been proposed in recent literature. Although the detailed arrangements differ depending upon whether the magnets are mounted on the rotor or the stator, the principle remains broadly the same. A movable piece of magnetic steel is used to “short”

New Single-Phase Flux Switching Axial Flux Permanent Magnet Motor
IEEE Transactions on Magnetics, 2017In this paper, a new topology of a single-phase flux switching permanent magnet motor (FSPM) is presented. Unlike conventional FSPMs, the air-gap flux flows in the axial direction, and therefore, it is named the flux switching axial flux permanent magnet motor (FS AFPM).

IEEE Transactions on Magnetics, 2015
Memory motors [1] [2] equipped with either single low-coercive force (LCF) or hybrid magnets have been extensively investigated due to the elimination of the associated excitation loss during the flux adjustment. Thus, they enable high efficiency operation within a wide range of speeds and loads.

A thermally switched flux pump
IEEE Transactions on Magnetics, 1975This paper describes a superconducting power supply (flux pump) of the transformer rectifier type in which the rectification is produced by thermal switching. The supply is intended for use with a superconducting magnet. At an operating current of 1000A the pump can charge a magnet at about 20 W with an efficiency greater than 93%.

Single flux quantum crossbar switch
IEEE Transactions on Appiled Superconductivity, 1997A crossbar switch has been designed using Single Flux Quantum (SFQ) gates exclusively for all internal functions. A 4/spl times/4 prototype has been fabricated in our Nb process foundry with J/sub c/ of 2000 A/cm/sup 2/. We report on the design and performance of the switch and of an individual crosspoint element at high data rates (/spl ges/1 Gbps). A

Servo flux switching PM machines
2014 International Conference on Electrical Machines (ICEM), 2014To date, flux switching permanent magnet (FSPM) machines have been treated due to their high torque capability. This paper investigates the suitability of FSPM for servo applications in terms of acceleration, stall torque and thermal overloading capability. The effect of different design parameters is investigated on a 3-phase 12/10 FSPM.

Flux-Weakening Capability of Flux-Switching Permanent Magnet Motor
2010 International Conference on E-Product E-Service and E-Entertainment, 2010A 12/10 flux-switching permanent magnet motor (FSPM) is described. Qualitative analysis of magnetic circuit indicates that a connection between stator segments is benefit to motor operation. From the basic principle of flux-weakening speed-extension operation, weaken magnetic factor and speed-extension multiple are calculated. The analysis results show

A novel transverse-flux switched-flux PM linear motor
2013 International Conference on Electrical Machines and Systems (ICEMS), 2013A novel transverse-flux switched-flux linear motor (TFSFLM) is developed in this paper, which has high thrust force density and low cost due to combining the advantages of transverse-flux structure and switched-flux structure. Based on 3D FEM model, two main parameters of motor configuration are investigated to acquire a higher thrust force.

Flux-regulation capability of hybrid-excited flux-switching machines
2012 XXth International Conference on Electrical Machines, 2012In this paper, the flux-regulation capability of a 12-stator-slot/10-rotor-pole hybrid excitation flux-switching (HEFS) machine with three types of magnet materials, namely Ferrite, SmCo and NdFeB, are evaluated based on finite element analysis. Due to the unique constrained dimensions between the magnets and field windings slots as well as the ...
