A magnetoresistor on the existing fitness equipment is matched with a solid disc iron block by an electromagnet in order to ensure enough magnetic permeability and resistance, an E-shaped electromagnet generates an open-loop magnetic field, a disc replaces a transverse iron to close the magnetic field, Lorentz force is generated in the rotation process of the disc, and current is generated in the disc. This is also a commonly used technique in the market. In order to achieve higher magnetic permeability and magnetic resistance, low-carbon steel is generally adopted to manufacture a heavier solid annular electromagnetic wheel, so that the cost is high, and the self weight of the electromagnetic wheel is also overweight. The reluctance device is often used for some reciprocating equipment on the body-building device, such as a rowing machine, a body-building vehicle, an elliptical machine and the like, the inertia force generated by the overlarge weight of the electromagnetic wheel in the using process is inertia, so that the phenomenon that the resistance of the front section is large, the rear section is empty or stepped or the force is obviously reduced due to the inertia of the electromagnetic wheel in the traction process is often generated, the user feels poor, the safety is not good during the use, and the body part of the user can collide against the body-building device due to the unstable force caused by sudden change. In addition, the deviation between the marked power and the actually measured power of the equipment is large, and the physical consumption of a user cannot be accurately calculated. Simultaneously because the electromagnetism wheel is heavier for guaranteeing the stability in the use, the mount pad of electromagnetism wheel needs the bilateral symmetry installation to erect the electromagnetism wheel to lead to the cooperation part many, the structure is complicated, has further increased the cost. In addition, the inertia force of the existing electromagnetic wheel is large, so that the electromagnetic wheel can rotate for a moment when a user stops moving, the equipment and the user cannot be stopped as synchronously as possible, and some braking devices are often required to be arranged.
