Abstract

PURPOSE: To make a twisting resonance hard to be induced when a pulsating torque is acting on a rotor by maing a torsional spring constant between a rotor and a disc at a low noise both shaft end type fan motor which drives a multi-vane fan at variable speeds by a thyristor control to have a proper relation.
