(4) The effect is not good, and the magnetic control state will be unstable. Therefore, it can only be used for lower price or not. The accuracy of the cries is from the material, and the material is moving 4, as described in Taiwan Patent No. G59007. If the manual operation mode is changed to the electric electric fork system, it is necessary to introduce the power supply from the external σΡ to supply the electric motor. The deer has no driving mechanism to use the drive mechanism to cause the device position to be limited to the power supply. The place will continue to create troubles and inconveniences such as liver and electricity, and even waste the use of space, resulting in a huge size of sports equipment, resulting in poor design, Taiwan Patent No. 077857 . Another type of electromagnetic brake structure is a better design that can obtain a more accurate resistance. It is the magnetic flux of the mine + the dip φ 4 is the electromagnet of the Renmin electromagnetic type, which requires high-current excitation, so that the large power generation must waste its power. When the temperature is too high, the magnetron state will also be unstable. And the electromagnetic brake structure is complicated and requires higher cost. Also, the American invention shown in Figure 1 is for US 5,71!, No. 404 and Figure 6, No. 6, No. 731, and that the two systems have strong magnetic field strength to directly generate braking force on the flywheel. Therefore, the internal power generation structure, including · power generation coils, silicon steel sheets, and magnets, etc., 胄6 shoulders 1 2 3 and juice on the inner periphery of the cast iron flywheel, resulting in a large volume, material taiji 6 1 cost Increase, and therefore the design system (4) is close to the flywheel shaft ~ position, so when the height is 2, the power will be generated, the braking part will be warm and not easy to dissipate. Therefore, how to get a better 3 electromagnetic brake system is a common problem in the industry. The inventor of this case is ignorant of the well-known problems, and the long-term experience is to study. Zhongneng 1309207 conceives a good solution, which can provide more convenient and practical products in the industry. SUMMARY OF THE INVENTION The main object of the present invention is to provide an eddy current electromagnetic brake system, which has a short structure, stable performance, and compact size, and can automatically adjust the load according to different amounts of motion, and can be self-powered and operated panel. Electric power, which can increase the output and reduce the cost of a brake structure for the feedback power of an exercise bike.

The electromotive force is generated, that is, an alternating current power generation is formed, and after rectification and filtering, the direct current is controlled by the weight controller to control the electromagnetic brake, and the electromagnetic power control torque is added, thereby setting and selecting the number of segments, and four control bits are used. For life, the control of the weight controller produces 2 segments equal to 16 segments, that is, *bits have a maximum of 16 strength levels; in addition, due to the higher level of control strength, electromagnets and cast iron The eddy current between the flywheels is also larger, the larger the eddy current is, the larger the torque is, and the more the resistance is increased. · The application in the pedal sports equipment is the load increase, the pedaling process Will be relatively difficult, their effect will be more obvious. Placing a non-magnetic metal plate or ring portion between the E-type electromagnet contact surface or the groove t of the gate-type electromagnet produces a larger eddy current because the non-magnetic gold 7 13〇92〇7 belongs to the genus The plate or ring will generate a repulsive force with the electromagnet, and the blade will increase the chip flow. Therefore, it is necessary to add a non-magnetic metal plate or ring to the system, such as..., this non-magnetic metal plate or ring, the electromagnet only Air can be used as a medium, and the generated eddy current is relatively small. Since the system is a eddy current electromagnetic brake. The spur system, so under the same torque value, the power generation and braking control circuit does not need to supply a large amount of voltage and current to the electromagnetic interior. , so the circuit is simple and small, $ & i compensation, can be installed in a cast iron flywheel into a single structure. [Embodiment] The structure of the present invention is described in detail, and the use and characteristics thereof are as follows. Referring to FIG. 3, the permanent magnet 13 and the stator silicon steel piece between the rotor central shaft 12 and the cast iron flywheel 11' are rotated by the foot pedal. Inductive electromotive force is generated in the steel month 15 , and the power generating coil 14 is wound around the 15 μg of the silicon steel sheet, and the number of generating coils increases, so that the induced current increases, and at the same time, the thundering medium, et ^ There is a thirst effect between the electromagnet 16 and the non-magnetic copper ring j 7 'The larger the induced current, the more the torque is added, the more the eddy current is, and the more the PCB control board 18 goes. Controlling the strength of the lightning magnetic modified 电 magnet, the structural analysis of the PCB control board 18 is shown in Figure 4. As shown in the block diagram of Figure 4, when three sets of induction AC generated by the Thunder ECG coil 14
