Właściwości silnika synchronicznego o magnesach trwałych z dwuczęściowym stojanem ograniczającym pulsacje momentu

The paper presents theoretical analysis and computation results of permanent magnets synchronous motor characteristics and performances. Two types of stator design to the motors were investigated. First structure of a stator core is a conventional slotted design of an asynchronous motor. The other structure has two pieces: an inner slotted core and an outer ring-shaped core. The inner slotted core has closed slots from a side of an air-gap. The field calculations basing on the two-dimensional Finite Element Method (FEM) was applied to determination of performances and parameters of permanent magnet synchronous motor (PMSM).
