Permanent magnet synchronous motor, in particular an electrical three-phase motor, comprising a rotor having permanent magnets, comprising a stator having a stator yoke, in which stator teeth having stator grooves positioned between them are arranged, - at least one winding being provided on each stator tooth, - the stator teeth being arranged layered in the axial direction of the stator as lamellae and being formed at least as two different lamellae, - the stator teeth in a first lamella being circularly interconnected at the ends thereof pointing towards the rotor, in each case by means of a connecting bridge, so as to form a stator star, and - the stator teeth in a second lamella comprising a break instead of the connecting bridge, - the rotor comprising at least two rotor packages arranged in the axial direction of the rotor, the at least two rotor packages being arranged rotated through an offset angle (γ) from one another about a rotor axis, characterised in that - the offset angle (γ) in angular degrees is less than or equal to half of the number of stator grooves, the offset angle (γ) being between the first and last rotor packages if there are more than two rotor packages, - the stator teeth being arranged as lamellae in the axial direction of the stator, in the sequence of a stator star comprising connecting bridges followed by one, two or three lamellae each comprising unconnected stator teeth in the form of individual teeth, - the lamellae being arranged alternating in this layered construction in the axial direction, - and a number n of rotor packages depending on an active axial length (Lstk) of the permanent magnet synchronous motor as follows: n = 1 or 2 if Lstk ≤ 40 mm n = 2 or 3 if 40 ≤ Lstk ≤ 60 mm n = 3 or 4 if 60 ≤ Lstk ≤ 80 mm n = 4 if 80 ≤ Lstk ≤ 130 mm. - at least one winding being provided on each stator tooth, - the stator teeth being arranged layered in the axial direction of the stator as lamellae and being formed at least as two different lamellae, - the stator teeth in a first lamella being circularly interconnected at the ends thereof pointing towards the rotor, in each case by means of a connecting bridge, so as to form a stator star, and - the stator teeth in a second lamella comprising a break instead of the connecting bridge, - the rotor comprising at least two rotor packages arranged in the axial direction of the rotor, the at least two rotor packages being arranged rotated through an offset angle (γ) from one another about a rotor axis, characterised in that - the offset angle (γ) in angular degrees is less than or equal to half of the number of stator grooves, the offset angle (γ) being between the first and last rotor packages if there are more than two rotor packages, - the stator teeth being arranged as lamellae in the axial direction of the stator, in the sequence of a stator star comprising connecting bridges followed by one, two or three lamellae each comprising unconnected stator teeth in the form of individual teeth, - the lamellae being arranged alternating in this layered construction in the axial direction, - and a number n of rotor packages depending on an active axial length (Lstk) of the permanent magnet synchronous motor as follows: n = 1 or 2 if Lstk ≤ 40 mm n = 2 or 3 if 40 ≤ Lstk ≤ 60 mm n = 3 or 4 if 60 ≤ Lstk ≤ 80 mm n = 4 if 80 ≤ Lstk ≤ 130 mm. n = 1 or 2 if Lstk ≤ 40 mm n = 2 or 3 if 40 ≤ Lstk ≤ 60 mm n = 3 or 4 if 60 ≤ Lstk ≤ 80 mm n = 4 if 80 ≤ Lstk ≤ 130 mm.
