Loading apparatus for exercise machine

Abstract: A loading apparatus for an exercise machine mainly includes a motor and a controller. The motor is connected to an exercise apparatus, on which a user may take exercise, of the exercise machine through a transmission device. The controller has a circuitry, which has at least a resistor, has opposite ends connected to the motor and a switch in the circuitry. Whereby, when a user takes exercise on the exercise apparatus of the exercise machine, it will turn a rotor of the motor through the transmission device to generate an induced current. The induced current flows through the circuitry and back to the motor to drive the rotor turning reversely. It provides the exercise apparatus a brake to make user taking exercise with a loading.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an exercise machine, and more particularly to a loading apparatus for the exercise machine.

2. Description of the Related Art

In present days, people go to gyms to take exercise on exercise machines, such as treadmill, exercise bike, stepper, elliptical trainer, and the like, for body building or weight loss. Some people buy the exercise machines to take exercise at home.

Conventional exercise machines are equipped with a loading apparatus to provide user taking exercise under different loading levels. Common loading apparatus includes friction type and magnet type. The friction type loading apparatus, like the brake, has brake pad pressing the flywheel to provide the exercise machine loading, and changes the loading by exerting the brake pad with different pressures. The magnet type loading apparatus provides magnets on the flywheel and a lever with magnet thereon. The lever is moved toward or away from the magnets on the flywheel to change the magnetic force between the magnets that may provide the exercise different loadings.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a loading apparatus of an exercise machine, which the principle of generating loading is different from the prior devices.

The secondary objective of the present invention is to provide a loading apparatus of an exercise machine, which needs no additional power to generate loading.

According to the objectives of the present invention, a loading apparatus for an exercise machine mainly includes a motor. The motor is connected to an exercise apparatus, on which a user may take exercise, of the exercise machine through a transmission device. A circuitry has opposite ends connected to the motor. Whereby, when a user takes exercise on the exercise apparatus of the exercise machine, it will turn a rotor of the motor through the transmission device to generate an induced current. The induced current flows through the circuitry and back to the motor to drive the rotor turning reversely.
