Disclosed is a permanent-magnetically excited electrical motor comprising a stator part (2), a rotor part (30) movable in relation to the stator part (2), and an air gap (8) between the stator part (2) and the rotor part (30). Either the stator part (2) or the rotor part (30) is provided with a flow path assembly for magnetic flow and coils (6), and the other of the two parts (2, 30) is provided with a flow path assembly for magnetic flow and permanent magnets (36). The inventive electrical motor comprises a flow conducting fluid (18) conductible for magnetic flow and at least one filling space (12; 16; 20; 38; 46; 48; 50) in the area of the flow path assembly of the stator part (2) and/or the rotor part (30), which can optionally be supplied with more or less flow conducting fluid (18) so as to modify the magnetic flow conductibility of the flow path assembly. |
