ABSTRACT:
An electromagnetic machine has a moving component, a stationary component, and a support component coupling the moving and stationary components in physical and electromagnetic proximity. The stationary component is a wound coil of insulated, electrically conductive tape defining a side face which has a plurality of spaced apart channels in it. The coil carries an electric current so that its opposite faces are north and south electromagnet pole faces and these pole faces are interrupted with spaced apart channels. The moving component is made up of a plurality of permanent magnets arranged in north-to-south pole alignment sequence and spaced apart. Non-magnetic pole surfaces of the magnets are positioned in close mutual proximity to the coil pole face. Electromotive forces are produced by electromagnetic interaction between the coil channels and the permanent magnet pole faces.
