An autonomous generation brake assembly comprises a hub acting as a first rotor and defines a receiving space therein by a peripheral wall. A plurality of permanent magnets are arranged alternatively along inner face of the peripheral wall. A stator is received in the receiving space of the hub and includes an armature coils corresponding to the permanent magnets of the hub, and a magnetic coils. A second rotor is rotationally received in the hub and located within the stator for working with the magnetic coils thereby generating eddy current therein for being attracted by the magnetic coils of the stator.
