Embodiment Construction

[0019] This "improved motor" is intended to overcome the standard motor ( figure 1 , 2 ) defects, the standard motor only uses the excitation part of the rotor ( figure 1 , 2 2) in the outside to attract or repel the stator ( figure 1 , 2 1) The magnet ( figure 1 , 2 6). The rotor is formed from the center of the rotor ( figure 1 , 2 4) The T-shaped part that radiates out ( figure 1 , 2 2) configuration, the T-shaped top forms the outer periphery of the rotor. The T-shaped section has a rod that is wound around the T-shape ( figure 1 , 2 3) of the winding ( figure 1 , 2 5) (the winding is usually copper wire), the T-shaped bar is connected to the commutator of the DC motor ( figure 1 , 2 7), but AC motors or other types of motors do not require a commutator. Whenever current flows through the winding ( figure 1 , 2 5), the T-shaped part ( figure 1 , 2 2) just become the electromagnet that has N and S pole. T-shaped top ( figure 1 , 2 2) by the magnets i...

Abstract

An electric machine including a direct current or an alternating current electric motor or generator and having a stator. The stator has an outer circumferential ring of equally spaced magnets. Spaced inwardly radially from the magnets is an inner circumferential ring of equally spaced magnets of opposite polarity to the first ring of magnets. A rotor including a plurality of H shaped energized electromagnetic coils is positioned in the space between the two rings of stator magnets with the rotor connected to a shaft whereby the pole pieces of the H shaped electromagnetic coils are influenced by the magnetic field of the two rings of stator magnets. The direct current machine being arranged to change the direction of electric current flow to the coils of the electromagnets.

Description

technical field [0001] This invention relates generally to electric motors, and more particularly to an improved electric motor utilizing both sides of the field coil. technical background [0002] Universal motor ( figure 1 , figure 2 ), regardless of DC or AC, adopts the magnetic principle that the same-sex magnetic poles repel each other and the opposite-sex magnetic poles attract each other. This principle and knowledge by changing the direction of current flow through the field coil changes the magnetic poles of the metal, ferrite or phenolic core passing through the field coil. Rotation is produced by this method by the push and pull action of either the rotor or the stator according to the design of the motor. All of today's designs suffer from the same design flaw of using only one end of the energized core to generate rotational motion of the rotor or stator. While there is no discomfort in using only one end of the permanent magnet, it is quite inefficient to ...
