Abstract: A submersible magnetic motor having improved rotary blades comprising a magnetic motor body, a magnetic rotor and a rotary impeller wherein the rotary impeller comprises a rotary hub provided with a plurality of blades which are uniformly distributed and extend outwardly around the periphery of the hub. The rotary hub is provided with an axial hole centrally formed therethrough for positioning an end of a central shaft of the magnetic rotor. The present invention is characterized in that the blades are each provided at the outer end edge with two stoppers and a fin freely pivoted therebetween, so as to be adjacent to the inner surface of the wall of the receiving chamber of the submersible motor. When the magnetic rotor is actuated to rotate, the fins each pivots to contact one of the two stoppers due to the resistance of the water such that the submersible motor can be maintained at a constant rotation speed, and the water pumping efficacy can be substantially improved.

Abstract: A switched reluctance machine includes a first element having a plurality of uniform poles and a second element having a first pole and a second pole. The first pole has a wide face and the second pole has a narrow pole face. The first and second elements are disposed for movement relative to each other such that the wide and narrow poles are moveable in spaced relation to the plurality of uniform poles.

Abstract: An electric motor has two exciter windings, independent of each other, on a stator, by which windings a resultant magnetic field can be produced. The motor includes a permanently magnetized rotor which has at least one pair of poles, the rotor changing its position as a function of the magnetic field, and the rotor being arranged axially on a rotor shaft. In the case of an electric motor which is of a small size and easy to manufacture, the stator is developed with several arms, and has an opening present at the center to receive the rotor. The individual arms are arranged around the opening and, there are, two pairs of opposite arms. The opposite arms are so bent towards each other so that, upon their receiving a respective exciter winding, they produce magnetic vectors which are perpendicular to each other.

Abstract: In the stepping motor, in which the stator core 4 is disposed outside the rotor 2 mounted on the rotation shaft, by the bearings 8, 9 mounted on the casings 10, the front and rear portion of the rotation shaft 1 are supported, and the casings 10, 11 are made of a press-molded metal plate.The thin portions 10b, 11b of the casings 10, 11, which are in contact with the stator core 4 support one portion of the outer circumference of the stator core 4. Also, by the alternately folded portions 10c, 11c of the thin portions and the projections 10d, 11d the bearings 8, 9 are supported. Whereby, the thin portions 10b, 11b cover one portion of the stator core, so that dusts are prevented from being entered. Further, the folded portions 10c, 11c and the projections 10d, 11d enable the bearings 8, 9 to install and keep the correct posture.

Abstract: A stator frame comprises a connection end (CE) casting having at least one CE integral partial tie bar extending from an inboard side of the CE casting and a pinion end (PE) casting having at least one PE integral partial tie bar extending from an inboard side of the PE casting. Each PE partial tie bar is welded to a respective CE partial tie bar.
