Abstract
Generally, a optical encoder is used to detect velocity for controling the electronic motor, the resolver is used when it is hard structurally to adjust encoder to electronic motor. so, the resolver has weakness in price in compare with encoder, but in case of controling the position of a magnetic polar, the resolver has stead detecting the absolute position of a rotator. This study is about the digital programing velocity detector which uses a minimum hardware : filter for detecting the revolve speed and rotor position of the motor by means of the resolver.
