The utility model discloses a shifting single phase direct current brushless motor, comprising a rotor, a stator module and an inverting circuit; wherein the stator module is internally provided with a stator coil and the converting circuit is internally provided with an inverting switch and a shifting switch. Utilizing the on state and the off state of the shifting switch to make the methods that the current flows through the stator module different can change the torsion-rotate speed characteristic curve of the direct current brushless motor so as to change the rotate speed of the motor and reach the function of the motor of shifting. The utility model effectively solves the technical problems that the current shifting single phase direct current brushless motor has high cost, bad radiating capability and big volume.
