Document Type and Number:
Japanese Patent JP2005245188
Kind Code:
A
Abstract:
To provide a method and a structure for instantly stopping a fan in which the fan is forcedly stopped in a short time after a power supply is cut off, and omitting the time for inertial rotation.
The moment the power supply for a fan is cut off, both ends of a coil for driving the fan is shorted, so the coil generates an induction current utilizing inertial rotation for the coil to generate the magnetic field in the opposite direction for stopping the fan.
