Claim:
An electric motor comprising: at least one rotatable sprocket; at least one drive shaft fixed for rotation with the sprocket; a non-ferrous tube forming an endless loop around the at least one sprocket; a carrier configured to circulate through the tube, the carrier engaged with the at least one sprocket whereby as the carrier circulates through the tube the at least one sprocket rotates; a plurality of permanent magnets arranged end-to-end in the carrier; a plurality of coils, each coil formed around the tube and spaced apart from each other coil, and each coil connectable to a power source; a control circuit operatively engaged with each of the plurality of coils and including a sequencing circuit for sequentially energizing the coils to move the carrier by repelling or attracting the magnets thereby causing the carrier to circulate around the tube rotating the at least one sprocket and the at least one drive shaft.
