An electric motor includes a stator, a rotor and a can arranged between the stator and the rotor, wherein the stator exhibits several stator pole pairs, which are each formed by two adjacent stator poles, which are designed in such a way as to generate oppositely polarized magnetic fields, and wherein the rotor exhibits a plurality of magnetic rotor poles distributed over the circumference, and is configured in such a way as to enable a magnetic flux between two adjacent rotor poles, as well as a pumping set with such an electric motor.
