Abstract
The present invention provides a power-saving tread mill. A power-saving tread mill includes: a pair of rollers 10, 20; and an endless belt 30 wound around the pair of rollers 10, 20, wherein at least one of the rollers 10, 20 has: an armature 24a having iron cores 24c and coils 24c wound around the iron cores 24c; and permanent magnets 23 rotatable with the one of the rollers 10, 20 integrally, and electromagnetic induction produced between the permanent magnets 23 and the armature 24a produces induced electric current flowing through the coils 24c when the one of the rollers 10, 20 is rotated.
Claims3
A conveyor structure comprising:
- at least two rollers;
- and
- an endless belt wound around the rollers;
- a drive motor configured to drive and rotate one of the rollers;
- at least a power-generating motor disposed inside a roll surface of one of the rollers, the roll surface contacting the endless belt,
- wherein the power-generating motor has an armature comprising an iron core, a coil wound around the iron core, a commutator comprising a plurality of commutator plates each connected to the coil electrically, permanent magnets fixed on an inner surface of the roller to face the armature and rotatable with the roller integrally, and a pair of conductive wires connected to the commutator plates electronically wherein one end of each of the pair of conductive wires extends to an exterior of the roller, and
- wherein the armature is fixed so as not to be rotatable together with the roller being rotated, and
- wherein the power-generating motor produces electric power by using electromagnetic induction produced between the permanent magnets and the armature when the roller is rotated, wherein the produced electric power is reused in the conveyor structure.
