Mobile working machines can be classified as light mobile machines that operate by battery power and heavy machines that work using a diesel engine. Both of these types include mechanical structures, which are driven by hydraulics. With the rising concern in global scale environmental issues, energy saving in vehicles and mobile machines is an important(More)
The energy efficiency of an electro-hydraulic forklift is significantly improved by using a permanent-magnetsynchronous-motor-servo-drive-based direct pump control to control the position of the fork without control valves. This paper provides a short evaluation of the hydraulic system and a more detailed analysis of the losses of the electric machine drive(More)
This paper investigates the effect of an induction machine (IM) drive on the efficiency of an electric energy recovery system of a hydraulic forklift. The control of the hydraulic system is implemented directly with a motor drive without control valves. The paper provides accurate evaluation of the hydraulic system and a detailed analysis of electric part(More)
