Abstract
The invention provides a permanent magnet magnetic resistance energy-saving motor and belongs to the technical field of motor energy saving. A permanent magnet salient pole magnetic pole and a winding salient pole magnetic pole are adopted to be combined to generate magnetic attraction on a rotor salient pole to enable a rotor to rotate, and the high energy saving rate is achieved. According to the permanent magnet resistance energy-saving motor, outage self-induced electromotive force generated by a main driving winding salient pole directly flows subsequently to a permanent magnet magnetic pole demagnetizing salient pole winding when the motor is shut down, so that when a magnetic field does not need to work for each phase of stator permanent magnet salient pole, the constant magnetic pulling force on the rotor by the permanent magnet salient pole magnetic pole constant magnetic field is reduced, due to the fact that the permanent magnet salient pole magnetic pole does not need a power supply for providing an excitation power supply and also does not need another power supply to provide an excitation power supply for a demagnetizing winding salient pole, the majority of electric energy consumed on permanent magnet salient pole magnetic pole excitation can be reduced, and the constant magnetic field of a permanent magnet is effectively used for acting to output power. When a main driving winding is powered off, electric energy similar to the power of an original power supply is generated and fully used again, and the purpose of saving electric energy is achieved.

salient pole is formed by silicon steel plate stacking, play by permanent magnetism magnetic pole and be magnetized into the magnetic pole identical with permanent magnetism magnetic pole, play the effect of conduction permanent magnetism magnet limbs polarity, also play and produce one and the rightabout magnetic field of permanent magnetism magnet limbs, offset and weaken the constant magnetic pull effect of permanent magnetism magnet limbs to rotor.Now A phase self-inductance power electromotive force by simultaneously afterflow of fly-wheel diode to energy storage capacitor and permanent magnetism magnetic pole demagnetization winding salient pole, demagnetization winding can produce a magnetic field contrary with permanent magnetism salient pole, at this moment permanent magnetism magnet limbs and demagnetization winding salient pole are because magnetic pole opposite magnetic fields can be reduced to minimum, produce magnetic field suction rotor with the mutually main driving magnetic pole of time D, A mutually in permanent magnetism magnet limbs self-inductance power electromotive force that the stationary magnetic field magnetic pull of rotor is produced during by the power-off of A phase offset hour through permanent magnetism magnetic pole demagnetization winding salient pole, rotor 1-1 salient pole central axis and stator A-A salient pole central axis coincide and become rotor 3-3 double-salient-pole central axis and the stator salient poles central axis D-D rotor that coincides and turn over 15 degree angles, now stator D-D phase salient pole central axis and rotor 3-3 central axis coincide, D phase infrared ray rotor position detector 6 infrared receiving tubes receive by the infrared ray of the 3-3 central axis reflector reflection of rotor-position detection dish 7 and output signal to singlechip controller, the mutually main driving winding of single-chip microcomputer output signal D salient pole control switch cuts out, the afterflow of the mutually main driving winding of D salient pole self-inductance power electromotive force is to the demagnetization of D phase permanent magnetism magnetic pole demagnetization winding time, the mutually main driving winding of the mutually main driving winding of C salient pole control switch pipe conducting C salient pole generation magnetic field suction rotor with salient pole 2-2 turns over 15 degree angle rotor salient pole 2-2 central axis and stator C-C central axis coincides, C phase infrared ray rotor position detector 6 infrared receiving tubes receive the infrared ray that coils 7 reflectors reflections by the detection of 2-2 central axis rotor-position and output signal to singlechip controller, the mutually main driving winding of single-chip microcomputer output signal C salient pole control switch cuts out, the mutually main driving winding of the mutually main driving winding of B salient pole control switch conducting B salient pole produces magnetic field
