    Abstract: There is provided a magnet type brushless generator capable of particularly controlling an output voltage to be uniform even in a driving operation at a variable rpm from a low-speed rotation to a high-speed rotation. The magnet type brushless generator includes a stator 20 having a plurality of stator magnetic poles around which winding wires for generating a rotation magnetic field are wound; a rotor 30 having a first field magnet 32 and a second field magnet 34 disposed coaxially with the first field magnet 32 in an opposed manner so as to be rotatable relative to the first field magnet; and a planetary gear mechanism 40 configured to control a relative rotation position of the first field magnet 32 and the second field magnet 34.
