[0002] An elliptical trainer is a full-body aerobic fitness machine that simulates natural walking, running, or climbing movements. It gets its name from the elliptical shape of its motion trajectory. The elliptical trainer is primarily driven by the user's legs; by gripping the handles and pushing and pulling back and forth, the user's feet move in opposite directions, pedaling forward and backward. The electrically controlled flywheel operates primarily using the principle of electromagnetic induction. When the elliptical trainer is powered on, the electromagnets generate magnetic force, which interacts with the magnets inside the flywheel to create resistance. The resistance is adjusted by changing the distance between the electromagnets and the flywheel, thus assisting in its rotation.

The movement trajectory is elliptical. When the drive shaft 141 rotates, the drive wheel 140, in cooperation with the drive belt 142 and driven wheel 143, drives the flywheel 150 to rotate. When the flywheel 150 rotates, according to training needs, the control panel 130, in cooperation with the data processing module 131 and the control module 132, energizes the corresponding electromagnet coils inside the electromagnet assembly 160 to generate magnetic force. The corresponding magnets on the inner ring wall of the flywheel 150 work together to form resistance. By energizing the corresponding electromagnets inside the electromagnet assembly 160, the distance between the corresponding electromagnets and the magnets on the inner ring wall of the flywheel 150 varies, thus creating corresponding resistance. This facilitates electronic control operation and makes operation more convenient. Furthermore, when ending or starting use, the lower abutment 180 facilitates braking of the flywheel 150. That is, by extending the electric telescopic rod 181, the lower abutment 180 and the pad 183 provide limiting support for the outer ring of the flywheel 150, making it easier to limit and brake the flywheel 150, making use more convenient and safe. The operation ends here.
