Hybride excited synchronous machine

摘要

The electrical machine has a set of stator laminations (2), enclosed by a magnetic yoke (1), carrying a stator winding (3) and a rotor (4) divided axially into two halves (5,6), each provided with permanent magnetic poles (9) of respective polarity. The permanent magnetic poles of both halves are offset by the pole spacing. An electrical excitation coil (16) is provided by an annular coil inserted in the gap between the two rotor halves, which are spaced apart along the rotor shaft (7).
