ABSTRACT:
A magnetic driving apparatus includes a bi-pole rotor wheel coupled to a speed adjustment motor and including a ferromagnetic wheel base and a magnetic rotor, the magnetic rotor including first and second magnetic rotor parts which are fixed to a circumferential surface of the wheel base in parallel with each other, spaced a first gap apart, and having opposite magnetic polarity to each other, each of the first and second magnetic rotor parts being formed by arranging alternatively magnetic rectangular blocks and non-magnetic spacers, and when being mounted to a circumferential surface of the ferromagnetic wheel base, the magnetic blocks and non-magnetic spacers of the first magnetic rotor part being aligned with those of the second magnetic rotor part. A linear stator disposed at a side of the bi-pole rotor wheel is formed by arranging alternatively magnetic rectangular blocks and non-magnetic spacers on a stator base and has a width substantially equal to that of the bi-pole rotor wheel, and wherein the bi-pole rotor wheel is spaced a second gap smaller than the first gap apart from the linear stator.
