A novel transverse-flux switched-flux PM linear motor

2013 International Conference on Electrical Machines and Systems (ICEMS), 2013
A 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.

Single flux quantum crossbar switch

IEEE Transactions on Appiled Superconductivity, 1997
A 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), 2014
To 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.

New Single-Phase Flux Switching Axial Flux Permanent Magnet Motor

IEEE Transactions on Magnetics, 2017
In 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).

Flux-weakening control performance of partitioned stator switched flux PM machines

2015 IEEE International Electric Machines & Drives Conference (IEMDC), 2015
This paper first investigates the flux-weakening control performance of two types of partitioned stator-switched flux permanent-magnet (PM) (PS-SFPM) machines and then proposes a novel mechanical flux-weakening technique. The PS-SFPM machine topologies, operation principles, and flux-weakening control method are described. In addition, it is shown that

Comparative Study of Wound-Field Flux-Switching Machines and Switched Reluctance Machines

IEEE Transactions on Industry Applications, 2017
In this paper, comparisons between two permanent-magnet-free (PM-free) machines, namely a wound-field flux-switching machine (WFFSM) and a switched reluctance machine (SRM), covering skewed-rotor and straight-rotor structures are conducted. The topologies and operation principles of the WFFSM are illustrated firstly.

Mitigation of magnetic flux saturation in dual-excitation flux switching motor

2015 IEEE Magnetics Conference (INTERMAG), 2015
Development of dual-excitation flux switching machines (DEFSMs) in which the combination of permanent magnet (PM) and DC field-excitation coil (FEC) as their main flux sources has been carried out over many years. This is due to their definite advantage of variable flux capabilities with high potential to gain much higher torque and power densities, as

Analysis of transverse-flux switched-flux permanent magnet linear motor

2015 IEEE Magnetics Conference (INTERMAG), 2015
In order to lower the cost, the switched-flux linear motor (SFLM) is proposed by combining both PMs and armature windings in short mover, which avoids long armature or long PMs as normal PMLMs. Moreover, SFLM combines the merits of linear motor and rotatory switched-flux motor, so they exhibit the advantages of bipolar flux-linkage and high thrust ...

A Novel HTS Flux-Switching Transverse-Flux Machine With Partitioned Stator

IEEE Transactions on Applied Superconductivity, 2019
This paper proposes and analyzes a novel high-temperature superconducting (HTS) flux-switching transverse-flux (HTS-FSTF) machine with partitioned stator, which keeps the merits of stator-excitation HTS machine with static seals. The key is to adopt the axial partitioned stator structure to realize the independent partition arrangement of armature ...

Analytical Time Domain Flux-MMF Model for the Flux Switching Machine

2018 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM), 2018
A modeling approach for the flux switching machine., based on the flux-MMF method is proposed. Under the model assumptions of radial flux and infinite iron permeability., the machine is simplified to current loadings and permeances along the air gap. These quantities are used to calculate the flux and induced voltage of the machine and are functions of
