1. DC Brushless Motor that is easy to start is characterized in that:

  • comprising;

    One pedestal is provided with a through hole, and this through hole one end is established a support sector, and this pedestal comprises a coil groups and an IC control piece;

    One rotor comprises the permanent magnet rings that a rotation axis and is provided with corresponding to the pedestal coil groups, and this permanent magnet rings comprises N, S magnetic pole, and this N, S magnetic pole respectively have a strong magnetic area, and has a magnetic pole junctional area between the N of described permanent magnet rings, S magnetic pole;

    Positioning piece is arranged at this pedestal, in the position between two adjacent lines circle groups wherein;

    When this rotor stops operating, and the suction magnetic orientation close mutually of a wherein strong magnetic area of the N of rotor permanent magnet ring, S magnetic pole with the keeper of pedestal, the strong magnetic area of each magnetic pole of permanent magnet rings is staggered with each coil composition that is fixed on pedestal, and the magnetic pole junctional area of described permanent magnet rings keeps clear of corresponding to described IC control piece.
