Abstract

An inertial structure for an exhaustion blower is essentially comprised of a base, a winding, a magnet, multiple blades and matching weights characterized by that each weight being placed in a space provided at the terminal of each blade to produce inertia when those blades rotate to increase torque, thus the greater wind shear volume for power saving.
