Abstract
A direct current motor comprises a magnet assembly having a pair of magnets for generating a magnetic field and a coil assembly located between the pair of magnets, the coil assembly and the magnet assembly being movable relative to each other. The coil assembly further comprises a first coil section and a second coil section which are electrically connected to each other. A current generator is electrically connected to the coil assembly and is operative to provide first, second and third currents. The first current is electrically connected directly to the first coil section and the second current is electrically connected directly to the second coil section whereas the third current is electrically connected to the first and second coil sections at a position connecting the first and second coil sections.
