It did not seem that long ago when I first came across a company selling a device called an inverter.
They told me that is was possible to take a standard 3 phase electric motor and vary the speed.
This was something up until then that you could only do with a hydraulic drive. Well the rest you will say, is history. We now see electrical drives of all sizes driven this way. Not only speed but torque control also.
Over recent years we have seen more and more electrical drives replace hydraulic drives. Where once a hydraulic drive was the only sensible solution there now sits a sparkling, clean, leak-free, efficient electric motor.
The only places I now see hydraulic drives now are mainly, marine and mobile applications or where power to size ratio is important.
Also electrical drives are more efficient and have considerable power savings with smoother control.
What does the future hold?
Is there an electrical linear drive around the corner that can compete with hydraulic rams, if so what is the future for Hydraulics systems?
