A High Torque Density Axial Flux SRM with Modular Stator
A novel structure of switched reluctance motors (SRMs) is proposed. The proposed structure uses the benefits of the axial flux path, short flux path, segmental rotor, and flux reversal free stator motors all together to improve the torque density of the SRMs. The main geometrical, electrical and physical specifications are presented. In addition, some features of the proposed structure are comp...
متن کاملEstablishment of Flux in Magnetic Cores
The same fundamental propagation and diffusion processes that establish current in conductors are also involved in establishing flux on the surface of magnetic cores and laminations but the spatial positions of the E and H fields are interchanged in the insulating medium. The E fields appear around the magnetic cores when the flux changes (∫Edl = dφ/dt), and the H fields are normal to idealized...
متن کاملMagnetic Flux Distribution in YBa2Cu307-x
The spatial distribution of magnetic flux in YBa2CY307, has been measured for various sinzered pellets and thin films. In ring-shaped samples macroscopic persistent currents have been observed. Tn discs, the penetration of the magnetic field bas been investigated, and in general qualitative agreement with the Bean model has been found. In some cases, however, pronounced deviations from the pred...
متن کامل3D-Printed Detector Band for Magnetic Off-Plane Flux Measurements in Laminated Machine Cores
Laminated soft magnetic cores of transformers, rotating machines etc. may exhibit complex 3D flux distributions with pronounced normal fluxes (off-plane fluxes), perpendicular to the plane of magnetization. As recent research activities have shown, detections of off-plane fluxes tend to be essential for the optimization of core performances aiming at a reduction of core losses and of audible no...
متن کاملA New Method for Computation of Axial Flux Permanent Magnet Synchronous Machine Inductances under Saturated Condition
Accurate computing of the saturated inductances of Permanent Magnet Synchronous Machine (PMSM) is very important during the design process. In this paper, a new method is presented based on the B-H characteristic of the stator material and unsaturated inductances formulations. This method is used to calculate the saturated inductances of the axial flux PMSM. The synchronous inductance and all o...
