Novel high power density integrated electro-hydraulic machine for electrical hybrid working vehicles is presented. The machine is dedicated to be used as a mechanical power source for hydraulic actuators with possibility of electrical energy recuperation. Advantages of using such a machine in mobile environments are discussed. The efficiency of the device is studied and compared with the traditional valve controlled systems.
