Investigation of direct current hydraulic drives

Abstract

The energy transfer at the hydraulic drives can be solving with direct current hydraulic drives and alternating current hydraulic drives. At the direct current hydraulic drives, the operating fluid flow in one way besides the alternating current hydraulic drives where it alternating periodically between the hydro generator and the hydraulic motor. Depending on the circumstances, it should be considered which drive is best for the intended purpose. In this paper we try to answer this question.
