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.

1 . A loading apparatus, which is mounted on an exercise machine having an exercise apparatus, comprising:
 a motor having a rotor connected to the exercise apparatus of the exercise machine through a transmission device; and   a circuitry, which has at least a resistor, having opposite ends electrically connected to the motor;   Whereby when the exercise apparatus of the exercise machine is moved, the rotor of the motor will be turned through the transmission device to generate an induced current flowing through the circuitry, and the circuitry will flow the induced current back to the motor to drive the rotor turning reversely.   
   
   
       2 . The loading apparatus as defined in  claim 1 , wherein the circuitry has a switch. 
   
   
       3 . The loading apparatus as defined in  claim 1 , wherein the circuitry has a variable resistor. 
   
   
       4 . The loading apparatus as defined in  claim 1 , wherein the circuitry includes a plurality of resistors in parallel connection and a switch. 
   
   
       5 . The loading apparatus as defined in  claim 1 , wherein the circuitry includes a plurality of resistors in series connection and a switch. 
   
   
       6 . The loading apparatus as defined in  claim 1 , further comprising a power supply connected to the circuitry.
