The utility model relates to a brushless
direct current generator with
hybrid excitation double salient, belonging to double salient motor, which comprises a
stator and a rotor, wherein, the
stator is composed of a
stator core (1), a permanent
magnet (2), a magnetizing coil (3) and the armature windings (4),(5),(6); the rotor comprises a rotating shaft (6), a rotor core (7); the yoke of the stator is provided with more than two groups of permanent magnets with symmetrical distribution, moreover the number of each group is more than two, and the neighboring permanent magnets are separated by three
stator poles; meanwhile the magnetizing coil with symmetrical distribution is arranged outside the permanent magnets. The utility model has no additional air gap; the
magnetic potential of the permanent
magnet and the
magnetic potential of the excitation make parallel connection so as to avoid the permanent
magnet being demagnetized by the magnet potential of the electric excitation. A plurality of sets of armature windings output a plurality of channels of
direct current after the rectification; wherein the output of the armature winding (4) sleeved on the stators between the permanent magnets can provide the power supply for the own
excitation coil (3) of the motor, which makes the entire motor work in an independent
electricity generation condition; therefore the utility model is in particular suitable for the
wind power generation situation and other separate supply application situation.
