The solar powered electric fan in the present inventronl uses a 1 2V three-phase BLDC motor as power source and can be directly connected to a solar cell without the need for the provision ofa step up transformer, thus saving on energy and protecting the environment, saving manufacturing cost and reducing the weight of the far. )'I Y4-L It/VLq/lV 191 f -VtNc 4 F16& ~2
