Piston motors: electronics, 0 degree capability, good efficiency at low speed
orbit motors: integrated valves, integrated brakes, high pressure shaft seals, integrated sensors
~Maurizio A, Marketing/Sales, Parma, Italy
Things like horse power limiter, torque limiter, new design in machine with load sensing and electronic control influence the choice of hydraulic motors.
~Claude L, General Management, Montreal, Canada

Improved manufacturing technologies make hydraulic motors more efficient and more reliable; Hydraulic control units lead to increased flexibility.
~George W, Engineering Consultant, Austria
Agricultural tractors in the future may be driven by hydraulic motors. Industrial equipment will also be a factor.
~Cyril L, Manufacturer, Sligo, Ireland
What we need in the near future will depend upon how much elect. power the person buying the machine wants to supply. Enough to supply a 40 watt light or enough to power 10-3000 homes or more.
