HOW TO MAKE THE SIMPLEST ELECTRIC MOTOR


The revolutionary motor system shown here uses a PhaseAble® circuit that connects a low-cost three-phase motor to a Single-Phase supply to make a high-performance single-phase motor system. The patented Smith PhaseAble® Enabler® has a single-phase 2-pole circuit breaker, line contactor, start contactor, start capacitor bank, and run capacitor bank. This injects currents into the motor windings so that the motor has the same full-load high efficiency from a single-phase supply that it would have on a balanced 3-phase supply

The most common type of electric motor is the brushed dc electric motor. This is the kind that you'll find inside essentially everything that moves (or shakes) and runs on batteries. This type of motor attracts an electromagnet towards a permanent magnet. When the two are close enough,the polarity of the current through the electromagnet is reversed, so that it now repels the permanent magnet, and thus keeps turning. It's quite easy to build a working model; Christian built this example for his third-grade science project. continue..

How does this work?http://www.evilmadscientist.com  
When you touch the wire to the side of the magnet, you complete an electric circuit. Current flows out of the battery, down the screw, sideways through the magnet to the wire, and through the wire to the other end of the battery. The magnetic field from the magnet is oriented through its flat faces, so it is parallel to the magnet's axis of symmetry. Electric current flows through the magnet (on average) in the direction from the center of the magnet to the edge, so it flows in the radial direction, perpendicular to the magnet's axis of symmetry.continue..
