In this paper a cuckoo search based optimal design of axial flux permanent magnet motor (AFPMM) is proposed. This approach employs a Cuckoo search (CS) technique as a search tool for optimal design solution of a AFPMM based on the value of the objective function. Several optimisation solutions are analysed and a best solution is proposed based on the values of the optimisation parameters and th...

Three speed controllers for an axial magnetic flux switched reluctance motor with only one stator, are described and experimentally tested. As it is known, when current pulses are imposed in their windings, high ripple torque is obtained. In order to reduce this ripple, a control strategy with modified current shapes is proposed. A workbench consisting of a machine prototype and the control sys...

Conventional high-speed flux-switching machines have either a high fundamental frequency or more even harmonics. This paper proposes novel six-slot four-pole axial permanent magnet machine for applications. The machine, consisting of two radially distributed stators and one rotor, can effectively eliminate harmonics in the flux linkage. First, structural parameters that affect performance motor...

in this research paper, the performance of an air-cored axial flux permanent magnet synchronous generator is evaluated for low speed, direct drive applications using 3d finite element modeling and experimental tests. the structure of the considered machine consists of double rotor and coreless stator, which results in the absence of core losses, reduction of stator weight and elimination of cog...

Resolvers are widely used in electric driven systems especially in high precision servomechanisms. Both encapsulated and pancake resolvers suffer from a major drawback: static eccentricity (SE). This drawback causes a significant increase in resolver output position error (RPE) which could not be corrected electronically. To reduce RPE, this paper proposes a novel structure with axial flux. Pr...

Axial flux motors have been in the focus of many research work due to their promising properties when compared conventional radial machines. permanent magnet synchronous (AFPMSM) studied literature were mostly limited surface-mounted machines (SPMSM), excluding only a few studies about axial internal (AFIPM) or magnet-assisted reluctance (AFPMaSynRM) Since numerous rotor topologies proposed and...

This paper deals with the design and optimization of a 2.1 MW rim-driven electric thruster for ship propulsion. For this purpose, double stator ironless rotor axial flux permanent magnet (AFPM) motor is considered as propulsion motor. The analytical model selected AFPM presented. magnetic field in machine calculated using 3D charge concept combination image theory permeance functions to take in...
