An autonomous generation brake having a dynamo, following rotation of a first rotor of an annular magnet in the core area an even number of armature coil with alternating polarities inside the first stator on the outer periphery are induced to produce an alternate current potential to be rectified at a rectifier wherefrom rated direct current is delivered to stimulate respective magnetic coils on the second stator of a braking device enclosing the dynamo; the second stator clamping internally a second rotor of a metal checked heat diffusion ring so that once the second rotor turns in rotation and respective magnetic coil on the second stator are stimulated, the interrelated movement occasioned thereby will induce a vortex upon the second rotor, meantime produce a braking torque sufficient to rapid diffusion of magnetically induced heat as well as the braking heat. Magnitidue of the direct current outgoing from the rectifier maybe regulated by a pulse regulator.
