<p>A hybrid DC electric motor with permanent magnet and electrical excitation comprises a motor body (1), a stator core (6), a rotor core (7), and a rotating shaft (4), with the rotating shaft (4) being arranged on the machine body (1), the stator core (6) being at least provided with three sets of stator armature windings (3), the rotor core (7) having provided on the surface thereof at least one pair of magnetic steel pieces (5), the rotor core (7) being wound with rotor excitation windings (12) having the same polarity as the surface polarity of the magnetic steel pieces (5), the rotating shaft (4) having fixed upon it a collecting ring (10), the machine body (1) having fixed upon it an electric brush assembly (9), and the rotor excitation windings (12) being connected to the collecting ring (10). On the magnet steel pieces (5) there is provided at least one flux hole (11) into which flux hole (11) the rotor core (7) is inserted. Electrical vehicles utilizing the present motor show structural simplicity, operational stability, good climbing capacity and high efficiency.</p> |
