Remote ControlThis can be directly controlled by manually adjusting EC handles to give it that electrical remote control of a pump displacement. And a variable motor can be given a variable pump by using a HDC on the motor which is controlled from the pilot pressure...

Sundstrand Hydro Transmission EDC – Constant Speed Control

Posted by Tammy Soper on

Sundstrand Hydro Transmission EDC – Constant Speed Control When you need more accurate control speed to have more independent motor load, then that is where constant speed control comes into play. The closed loop speed controls can offer you the constant control you want by applying a proportional, derivative and integral closed loop control application to give more motor/pump speed. The feed forward control lessens momentary moments during the pump speed changes. An EDC controls pump displacement.More recent application of this constant control speed is on a hydrostatic transmission drive for a AC electrical generators. They can be hydro statically...
