A Study on the Optimal Efficiency Drive of a Direct-Current Motor
직류전동기의 고효율화 우\ulcorner에 관한 연구
Abstract
This paper considered the energy saving problem of D.C. motor in arbitrary load condition. We can improve efficiency by maintaining the proper ratio of armature current/field current. First, the condition of maximizing the efficiency was obtained, and then the real time control was implemented by using microprocessors. As a result, the efficiency was improved in spite of constant output. For example, the efficiency at 1/5 load was improved from 56.7% to 80%.
