Comparison between parallel and radial magnetization in PM fractional machines

PM fractional machines adopting bonded magnets: Effect of different magnetizations on the energetic performance

“…The magnetizations here considered are the parallel and the radial one [11], which present different levels of complexity and required devices.…”

“…But a subject which constitutes object of technical debate concerns the type of the possible magnetization process [7], [8], [9], [10]; in this work a comparison will be carried out about the motor performances related to the two main types of magnet magnetization: parallel and radial [11], [12], [13], [14] [15], as it has already been done for the case of ferrite magnets.…”

“…The motor considered in the present activity is equipped with bonded magnets [11], whose magnetic data are reported in the following Table I The aim of this work involves the evaluation of the impact of the magnetization direction on the machine performance [7], [9]. The magnetizations here considered are the parallel and the radial one [11], which present different levels of complexity and required devices.…”

Analytical Model on Real Geometries of Magnet Bars of Surface Permanent Magnet Slotless Machine

“…Authors of [28] consider that the parallel magnetization is easier to obtain for the radial magnetization tiles. More they note that the parallel magnetization induces iron losses slightly larger than the radial magnetization.…”

“…In magnetic field calculation of electrical permanent magnet machines, most authors consider a real direction of magnetization (parallel) [6][7][8][9][24][25][26][27][28]. They consider only one permanent magnet by pole.…”
