Abstract
High-torque permanent magnet synchronous electric motors (HPMSM) are widely used in many industries due to their minimum weight and size parameters, low vibrations and high efficiency at maximum torque. A special effect from the use of HPMSM can be achieved in the aerospace industry as electric motors for various executive units, for example, a flap drive, slats or elevators. The purpose of this work is to make experimental studies and research using the finite element method of the characteristics and parameters of HPMSM with magnetic cores of ALM with more than 6 slots, created according to the technology developed by the authors for manufacturing magnetic cores of ALM. This article considers the experimental studies that have been conducted to evaluate the effectiveness and features of the ALM application in HPMSM. In order to assess the effectiveness of using ALM HPMSM with a magnetic core made of ALM, it is compared with a similar HPMSM, whose magnetic core is made of electrotechnical steel. A multi-polar HPMSM with a fractional toothed winding is considered. The research results show the possibility of creating HPMSM with magnetic cores of ALM and the effectiveness of using ALM in HPMSM has been proven.
