Three-phase synchronous machine for power train of motor car, has rotor core having recesses that are multiplied in such way that two layers, preferably three layers of permanent magnets are arranged

摘要

The synchronous machine has a stator (S) having stator core (SK) with grooves (N1,N2,N3) in which wire coils are arranged. The number of grooves in the stator core is multiplied twice preferably thrice, with the number of grooves with wire winding according to pole and phases (U-W) of three-phase current. The multiplied grooves comprise the wire windings in adjacent poles and phases of phase current in combination. The number of recesses (A1,A2,A3) in the rotor core (RK) is multiplied in such a way that two layers, preferably three layers of permanent magnets are arranged.
