A bi-directional reversible submersible motor comprising:
- a housing, said housing having at least one bracket fixedly mounted on the inside thereof and two opposite open ends;
- a sleeve affixed to said at least one bracket inside said housing, said sleeve holding a winding around an inside wall thereof;
- two water guide plates respectively fastened to the two opposite open ends of said housing, said water guide plates each having a center through hole;
- a shaft and fan blade assembly rotatably suspending in said sleeve, said shaft and fan blade assembly comprising a tubular shaft inserted through said sleeve, a magnet affixed to and extending around the periphery of said tubular shaft and suspending in said sleeve, and two fan blades respectively fastened to two distal ends of said tubular shaft;
- two caps respectively fastened to the two opposite open ends of said housing and respectively covered on said water guide plates;
- two semispherical grilles respectively fastened to the two opposite open ends of said housing and surrounding said caps, said semispherical grilles each having a plurality of radial slots and a coupling groove around the periphery of one end thereof;
- and
- two guards, said guards each having a circular coupling portion respectively pivotally coupled to the coupling grooves of said semispherical grilles and a semispherical guard shell extended from said circular coupling portion.
