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.

Claims

1. A conveyor structure comprising:

at least two rollers; and

an endless belt wound around the rollers, wherein

at least one of the rollers has armatures each having an iron core and coil wound around the iron core; and

permanent magnets rotatable with the one of the rollers integrally, and wherein

electromagnetic induction produced between the permanent magnets and the armature produces an electric current flowing through the coils when the one of the rollers is rotated.

2. A tread mill having the conveyor structure as claimed in claim 1, wherein a person can run on the endless belt.

3. A conveyor having the conveyor structure as claimed in claim 1, wherein the conveyor can convey an article placed on the endless belt.
