Abstract
The present invention provides an instantaneous fan stopping method and structure thereof. The method and structure can eliminate the inertial rotating state of the fan when the power supplied to the fan is cut off. In accordance with the present invention, a closed circuit is formed between the two terminals of the coil used to drive the fan. When the closed circuit is formed, the inertial rotation of the fan can generate an induced current in this coil, which, in turn, generates a magnetic force to stop the fan.
