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

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 ...

Analysis of Transverse-Flux Linear Switched-Flux Permanent Magnet Machine

IEEE Transactions on Magnetics, 2015
The transverse-flux linear switched-flux permanent magnet machine is investigated by 3-D finite-element analysis in this paper. The topology of the machine, as well as the machine operation principle, is introduced first. In order to improve the thrust force performance of the machine, two aspects are analyzed. One is the average thrust force, which is

Novel Permanent Magnet Switching Flux Motors

Proceedings of the 41st International Universities Power Engineering Conference, 2006
Permanent magnet switching flux (PMSF) motor combines the advantages of both SR motor and PM motor. All 3-phase PMSF motors reported previously have 12 poles on the stator where a magnet is embedded in each pole and 10 poles on the rotor. In this paper, a new structure motor is proposed. It has also 10 poles on the rotor, but only 6 poles on the stator.

Transverse flux tubular switched reluctance motor

2008 11th International Conference on Optimization of Electrical and Electronic Equipment, 2008
A transverse flux tubular switched reluctance motor of a particular construction is presented. The traction force equations are obtained based on two simplified models and a sizing designing procedure for the motor is developed. A two dimensions finite element method (2D-FEM) analysis is performed in order to check the analytically calculated ...

Stator-Flux-Oriented Fault-Tolerant Control of Flux-Switching Permanent-Magnet Motors

IEEE Transactions on Magnetics, 2011
Flux-switching permanent-magnet (FSPM) motors are a newly developed brushless AC (BLAC) machine having magnets in the stator. This paper proposes and implements a stator-flux-oriented (SFO) control strategy for fault-tolerant operation of FSPM motors. The key is to set the q-axis component of armature current invariant before and after the fault.

DC excited flux-switching motor: Rotor structural optimization

2014 17th International Conference on Electrical Machines and Systems (ICEMS), 2014
This paper investigates the effect of various rotor structures on the torque production capability of DC excited flux-switching motors. In these machines two set of windings, excited with DC and three-phase AC currents, are placed within the stator and the rotor structure should ensure that the applicable magnetic circuit is present to achieve both a ...

Axial Flux Switched Reluctance Machines

2019
Switched reluctance machines (SRM) can fall into three classifications based on the direction of flux through the air gap: radial, transversal, and axial flux. The first axial flux machine was developed in 1821 by British physicist Michael Faraday. He invented a primitive disc motor that was the early form of an electric machine.

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
