Abstract
A permanent magnet excited electric machine includes a stator and a moving part movable relative to the stator. One of the stator and moving part has an electric winding system in the form of a single or multiple 3-phase system. The other one of the stator and moving part has permanent magnets. The winding system, in the form of a delta connection, has an inductance such that the related total reactance xduring rated operation according to x=ω·L·P/(Z·U) is at least 0.8, wherein ωis the electric angular frequency of the winding system during rated operation, Lis the phase inductance of the winding system in star connection, Pis the power of the machine during rated operation, Zis the number of 3-phase systems of the machine, and Uis the amount of the induced conductor voltage during rated operation.
