Title:
ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2014/166872
Kind Code:
A3
Abstract:
The invention relates to an electric machine, which comprises a stator (1) and a rotor (2) that can be moved in relation to the stator. The stator (1) has a first multi-phase winding (I) and at least a second multi-phase winding (II), which each comprise two partial windings (A1, A2) mechanically moved in relation to each other. In a groove (3) of the stator, a number of windings (Nw1) of the first partial winding (A1) of a multi-phase winding is different from a number (Nw2) of windings of the second partial winding (A2) of said multi-phase winding. The stator (1) has a number of grooves (3) that is twice the number of grooves minimally required for a given pole pair number p of the rotor (2) for one of the multi-phase windings.
