Abstract

This paper proposed a hydraulic pump system which uses a variable speed SR drive and constant capacity pump. The base and maximum speed, torque are determined from the mechanical specifications of hydraulic pump. The drive system is set to have minimum power consumption during the keeping of preset oil-pressure. In order to save the power consumption of hydraulic pump, power and oil-pressure signals are feedback to DSP controller, and SR drive controls the operating speed of SRM. A 2.2 kW, 12/8 pole SR motor and DSP based digital controller are designed and tested with experimental set-up. The test results show that the system has some good features such as high efficiency and fast response characteristics.
