Braking assembly with self-generating power energy

摘要

A braking assembly with self-generating power energy is provided with a plurality of permanent magnets arranged around a rotary central shaft of the braking assembly to alternate N poles and S poles, at least one power-generating coil provided on a stator of the braking assembly nearby the permanent magnets for generating an induced electromotive force when the rotary central shaft rotates, a pulling mechanism provided on the stator for pulling two free ends of two curved braking plates mounted on the stator depending on the induced electromotive force generated by the power-generating coil and thereby regulating a brake force of the braking assembly, and at least one compression spring provided between each of the curved braking plates and the stator to provide a radially outward restoring force to the curved braking plates.
