The present invention discloses a radial superposition magnetic circuit permanent magnet direct current motor. The motor comprises a plurality of stators and rotors installed in the stators, and each rotor includes a rotor permanent magnet tile configured to drive the rotation of a rotating shaft; each stator includes a stator iron core lamination stack, a winding wound on the stator iron core lamination stack, and after the winding is powered on, a salient pole electromagnetic field is formed on the stator iron core lamination stack; the stator also includes a stator magnet and a magnetic conductive mechanism configured to conduct the permanent magnetic line of the stator magnet, the permanent magnetic line of the stator magnet at least passes through the magnetic conductive mechanism and the salient pole of the stator iron core lamination stack to form a semi-open magnetic loop so as to allow the semi-open magnetic loop and the salient pole of the stator iron core lamination stack to generate superposition reinforcement after the winding is powered on; and the superposition reinforcement is effected on the rotor permanent magnetism tile to drive the rotation of the rotating shaft to push the rotor to continuously output the torque kinetic energy for pushing the rotor and being higher than a simple electromagnetic field. The radial superposition magnetic circuit permanent magnet direct current motor has super-high efficiency, super-low energy consumption and excellent combination property.
Description
technical field [0001] The invention relates to the field of permanent magnet direct current motors, in particular to a radial superimposed magnetic circuit permanent magnet direct current motor. Background technique [0002] The existing permanent magnet DC motors are roughly divided into two categories, one is permanent magnet stator and electromagnetic rotor, which are mainly controlled by traditional steering gear and brushes, commonly known as permanent magnet brushed DC motors; the other is electromagnetic The stator and permanent magnet rotor are mainly controlled by position sensors and control drive circuits, commonly known as permanent magnet brushless DC motors. Permanent magnet DC motors are widely used in various portable electronic devices or appliances, such as tape recorders, VCD players, automobiles, motorcycles, ships, aviation, precision machine tools, bank currency counters and other industries. The above two types of permanent magnet DC motors have one ...
