Q:
What new technologies are influencing hydraulic motor design?
41 answers
Answers:
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

1) Distributor valve or port plate 2) Hydrostatic balance piston with orifice jet 3) High pressure shaft seal

~Colin G, Design Engineer, Shanghai, P.R.China

Electronics. Coordination with engine. Automotive style propel that responds to engine rpm with fine inching control.

~John M, Technical Support, Vancouver, WA
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.

~Lloyd H, Technical Support, Moore, OK

Improved power to weight, higher torque outputs, more compact design including higher working pressures.

~Marketing/Sales, Brendale, Australia

Monitoring of pump: temp, flow, inlet supply and filtration, computerization.

~Toddy R, General Management, Point Lisas, Trinidad W>I>

Compactness, PLC controls, high torque/low speed requirements, maintainability

Q:
From your perspective, which companies are creating the most innovative hydraulic motors?
48 answers
Answers:
Sauer-Danfoss is a very good manufacturer of hydraulic motors and also quite impressive in creating, designing and marketing a new product from scratch to the production level and to the O.E.M. customer.
~Claude L, General Management, Montreal, Canada
1)Hagglunds drive (radial piston motor) 2)Linde hydraulics (axial piston motor) 3)Sauer-Danfoss (orbital motor)
~Colin G, Design Engineer, Shanghai, P.R.China

Piston motors: Sauer-Danfoss. Orbit motors: Sauer-Danfoss, Eaton, Parker

~Maurizio A, Marketing/Sales, Parma, Italy
I've used so many types and suppliers - Sort of have a fancy for Vickers.
~Leo B, Design Engineer, Beauharnois, Quebec, Canada
I'm thinking at company Danfoss with Nessie technologies, that using water pressure, very important for food industries in the case some hose under pression can explode, The oil will contaminate all product in the area, water is water, and the contamination is very low.
~Graziano R, Project Manager, Modena, Italy

No one company in particular, however most innovation appears to be originating in Europe.

~Marketing/Sales, Brendale, Australia

Porclain, Parker and Hannifin, Rexroth Bosch, Syh.

~Purchasing, Sydney, Australia
That is not apparent. Old companies have gone out of business and new companies don't seem to exist. Maintenance of equipment is a real problem.
~Engineering, Design, Owego, NY
Most of them, but each a little bit differently.
