The invention discloses a brushless claw-pole excitation
wind power generation device which comprises a
fan blade, a generator, a bracket, a
wind direction rudder, a
slip ring assembly and a fixed seat. The
fan blade is fixed on a rotating shaft of the generator by a
screw thread; the generator is fixed at one end of the bracket; the other end of the bracket is connected with the
slip ring assembly; the
slip ring assembly is fixedly connected to the fixed seat; and the
wind direction rudder is fixed at one side, which is close to the
fan blade, of the bracket. According to the invention, by adopting the brushless claw-pole excitation generator, power generation of the device is not limited by the rotating speed, the device can normally work at different rotating speeds, and working stability of the device in various environments is improved; due to adoption of the structure that the
wind direction rudder and the bracket are fixedly connected at the side close to the fan blade, when the wind direction is changed, orientation of the fan blade can be well changed; meanwhile, compared with a conventional
wind driven generator, the brushless claw-pole excitation
wind power generation device has the characteristic that mechanisms such as a rudder stock and the like are omitted, and thus, the brushless claw-pole excitation
wind power generation device has a simple structure and a small
working space; and the excitation generator adopts a front-
stator and totally sealed structure, so that a motor does not need to be maintained, and the brushless claw-pole excitation
wind power generation device has strong adaptability to the environment.
