IPC: H02P27/06
Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To autonomously control the pressure and the flow by only connecting a power source line without using an input signal line while eliminating the input of the command pressure and the command flow from the outside. SOLUTION: Power is supplied from a converter 17 to an inverter 3 or from a power source circuit 18 for controller to a controller 11 by only connecting an alternating current power source 15 to a power source connecting terminal 16. The controller 11 outputs the control signal to the inverter 3 so that the pressure and the flow of the fluid to be discharged from a fixed capacity type hydraulic pump coincide with the predetermined value on the basis of the output from a pressure sensor 6 and a rotation sensor 5 without receiving the pressure command signal and the flow command signal from outside. Since the power is supplied by only connecting the power source line to the power source connecting terminal 16, wiring is simplified.
