1. the degaussing energy of a utilization handle cut-out phase (X or Y) directly sends the two-phase (X of the electronic commutation of next phase (Y or X) to, Y) Poewr control method of reluctance motor, wherein phase (X or Y) is one group of winding that is encouraged simultaneously, the yoke (11) that is installed on described winding goes up and produces self induction voltage (Ua) when cutting off, described self induction voltage (Ua) is directed into the bypass winding (113Y) of next phase (Y) via the bypass diode (22) that connects first phase (X), it is characterized in that, just make the positive rod and the power switch (21X of the power source that is connected motor of flowing through afterwards in a delay (t), main winding (112X 21Y), principal current 112Y) (Ip) conducting, the duration of wherein said delay starts from by means of carrying out described phase (X being used for the hall detector of phase control (31) the place ahead rotor rotated position indicating device (32), during Y) commutation, and end at described phase (X, Y) winding is connected to the power switch of negative rod of power source of motor, and (21X is during 21Y) connection.
