Patent ID: 6952063

Claim:
A braking assembly with a manageable self-generating power, comprising: a stator having an outer circumferential surface and a central shaft hole for a rotary central shaft to extend therethrough; a rotor, located around the outer circumferential surface of the stator to rotate along with the rotary central shaft when the rotary central shaft rotates; a pair of curved braking plates, each having an outer circumferential surface, disposed between the outer surface of the stator and an inner surface of the rotor; two adjacent ends of the two curved braking plates pivotally connected via a pivot shaft respectively to a predetermined position on the circumferential surface of the stator, and the other two adjacent ends of the two curved braking plates being free ends; a plurality in first permanent magnets fixed to the outer circumferential surface of each the curved braking plate; a pulling mechanism provided on the stator, which comprises a motor to pull the curved braking plates by the free ends; a plurality of second permanent magnets, each of which having a north pole and a south pole, arranged around an outer surface of the rotary central shaft, so that the north poles and the south poles of the second permanent alternate around the rotary central shaft; a plurality of power-generating coils being provided on the stator at a position close to the second permanent magnets around the rotary central shaft, whereby when the rotary central shaft rotates and brings the second permanent magnets to rotate at the same time, an AC voltage is generated through induction of each of the power-generating coils; and a circuit board mounted at the stator, comprising a control circuit and a power management circuit which is connected to the power generating coils for receiving the AC voltages generated at the power generating coils and supplying the AC voltages to the control circuit for rectifying and stabilizing to generate a DC voltage to drive the motor of the pulling mechanism to rotate; and by means of the pulling mechanism, the air clearance between the outer circumferential surfaces of the curved braking plates and the inner circumferential surface of the rotor is controlled, and hence a braking force of the braking assembly is regulated.
