Abstract: The invention relates to an electric machine comprising a stator (8) and a rotor (9). The stator comprises grooves (1, 2) for receiving at least two coils of an electric winding. The first coil comprises a first winding number (n1) in a first groove and a second winding number (n2) in a second groove (2). The second coil comprises a first winding number (n1?) in a first groove and a second winding number (n2?) in a second groove (2).
Abstract: An electrical machine is provided, comprising a stator (8) and a rotor (9). The stator comprises slots (1, 2) for receiving a coil of an electrical winding. The coil has a first number of turns (n1) in a first slot (1) and a second number of turns (n2) in a second slot (2).
Abstract: An electrical machine comprising a stator (1) and a rotor (2) movable relative to the stator is provided. The stator (1) comprises a doubled number of notches (3) with respect to a pole pair number p of the rotor. This is combined with differing numbers (n1, n2) of turns per phase winding or with differing tooth widths (Z1, Z2) of teeth (6, 7) of the stator which are formed between neighboring notches (3).
Abstract: An electrical machine is provided, comprising a stator (7) and a rotor (8) which can be moved relative to the stator (7). The stator comprises slots (1, 2) for receiving electrical windings (+A, ?A). In operation of the electrical machine, an operating wave of the magnetomotive force differs from a fundamental wave of the magnetic flux. A mechanical barrier for the fundamental wave of the magnetic flux is provided in at least one portion of the stator.
