Flywheel magnetic control resistance apparatus for indoor exercise facilities

Abstract

A flywheel magnetic control resistance apparatus for indoor exercise facilities includes a flywheel and a holding dock located on the periphery of the flywheel with a plurality of permanent magnets and electromagnets laid thereon alternately. The holding dock is formed in an arched shape outside the periphery of the flywheel and concentric with the flywheel. The electromagnets are connected to a power supply to allow the coils winding thereon to generate magnetic attraction forces. The current on the electromagnets is alterable to change the magnetic attraction forces between the permanent magnets and the electromagnets. Thereby the vortex resistance of the flywheel can be changed.

1 . A flywheel magnetic control resistance apparatus for indoor exercise facilities, comprising: 
 a flywheel; and    a holding dock which is located on the periphery of the flywheel and has a plurality of permanent magnets and electromagnets laid thereon alternately in an arched manner corresponding to the direction of the flywheel, the electromagnets being connected to a power supply, the current flowing on the electromagnets being alterable to determine the magnetic attraction force between the electromagnets and the permanent magnets thereby to change resistance on the flywheel.    
   
   
       2 . The flywheel magnetic control resistance apparatus of  claim 1 , wherein the number of the electromagnets is alterable according to requirements, and the resistance on the flywheel increases when the number of electromagnets increases, and the resistance on the flywheel decreases when the number of electromagnets decreases.  
   
   
       3 . The flywheel magnetic control resistance apparatus of  claim 1 , wherein the holding dock is located outside the periphery of the flywheel.  
   
   
       4 . The flywheel magnetic control resistance apparatus of  claim 1 , wherein the holding dock is arch-shaped and has a center shaft, the flywheel having a center hole coupled on an axle, the axle having an axle hole to be coupled by the center shaft, the permanent magnets and the electromagnets being located alternately on an outer periphery of the holding dock.
