Abstract:
A device capable of increasing the rotation speed of a magneto motor, comprising:a magneto motor comprising a stator portion and a rotor portion, said stator portion being provided to let exciting coil windings be disposed therein, said rotor portion being a rotary rotor having a permanent magnet, said rotor portion corresponding to said stator so that an armature can react to rotate; a plurality of sets of magnetic sensors installed at said stator portion with various kinds of angles and used to sense rotary pole variation of the permanent magnet of said rotor portion, the exciting coils of said stator portion and the rotary pole of said rotor portion thus generating variation relations of different angles, synchronous or advance phenomenon of conduction time difference between the detection signal and the exciting coils occurring, thereby generating various kinds of armature reactions of different strengths; and a magnetic detection signal selection circuit letting said plurality of sets of magnetic sensors integrate a detection output signal via instructions of signal terminals, various kinds of detection output signals letting the exciting coils of said stator portion have different conduction time differences, various kinds of conduction time differences letting said stator portion and said rotor portion generate individual constant armature air gap magnetic flux densities, individual constant magnetic flux densities generating individual constant torsion coefficients KT so that said magneto motor can generate various kinds of operational rotation speeds.
