Abstract
A power-generating magnetic sensing equipment comprises a magnetic sensing read head and a magnetic scale. The magnetic sensing read head includes a power-generating device and a signal sensing control device. The magnetic sensing read head moves with respect to the magnetic scale to make the power-generating device produce changes of magnetic field to induce the electric current, so that the power-generating device is able to continuously supply the power to the signal sensing control device, thus keeping the signal transmission uninterrupted.
