A Novel Technique on the Analytical Calculation of Open-Circuit Flux Density Distribution in Brushless Permanent-Magnet Motor
Both the cogging and electromagnetic torques depends on the shape of the flux density distribution in the airgap region. A two-dimensional (2-D) analytical method for predicting the open- circuit airgap field distribution in brushless permanent magnet motors, considering the direction of magnetization, i.e., radial or parallel, and the effect of real shape of stator slot-openings is presented i...
متن کاملAnalytical Modeling of Magnetic Field Distribution in Inner Rotor Brushless Magnet Segmented Surface Inset Permanent Magnet Machines
Brushless permanent magnet surface inset machines are interested in industrial applications due to their high efficiency and power density. Magnet segmentation is a common technique in order to mitigate cogging torque and electromagnetic torque components in these machines. An accurate computation of magnetic vector potential is necessary in order to compute cogging torque, electromagnetic torq...
متن کاملMagnetic Flux Distribution of Linear Machines with Novel Three-Dimensional Hybrid Magnet Arrays
The objective of this paper is to propose a novel tubular linear machine with hybrid permanent magnet arrays and multiple movers, which could be employed for either actuation or sensing technology. The hybrid magnet array produces flux distribution on both sides of windings, and thus helps to increase the signal strength in the windings. The multiple movers are important for airspace technology...
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 کاملReview in Transverse Flux Permanent Magnet Generator Design
Recently, Transverse Flux Permanent Magnet Generators (TFPMGs) have been proposed as a possible generator in direct drive variable speed wind turbines due to their unique merits. Generally, the quality of output power in these systems is lower than multi stage fixed speed systems, because of removing the gears, so it’s important to design these kinds of generators with low ripple and lowe...
