ABSTRACT:
A magnetic adjustable loading device with eddy current comprises a flywheel and a rotor made from metal conductor. A stator comprises with a magnetic plate and permanent magnet. By changing the air gap between the rotor and stator, the magnetic flux density is changed. Characterized in that the axial displacement of the stator is replaced by a stator which performs the radial displacement. The loading or resistance can be adjusted in a stepless manner. The overall dimension of the loading device can be reduced and it can be applied in a more flexible and subtle way.
