Excellent post and hydraulic pumps

Excellent post. I want to further support the importance of properly sizing the hydraulic pump for the machine. An inproperly sized pumped, as most of you know, can cause all sorts of expensive problems.

HYdraulics may be more efficient than some gearboxes, but in many cases the better efficiency would come from being 100% electric everything. What hydraulics can do very well is put the most energy in  a small place, and a cylinder will live well even if you stall it So there is a time and place where hydraulic power is the best choice, but it is not everywhere. Most time changing to hydraulics is not done for efficiency.

Let's be clear here.  This article argues that hydraulics are more efficient than GEARBOXES, not electric motors.  Most hydraulics are powered by electric motors in the first place, and I am quite sure that a high efficiency direct drive brushless motor is more efficient than the induction motors usually used for hydraulics.  However, if you have a gearbox in the drive train, you often lose 40% to the gearbox, and his points about bulk and weight are still well taken in certain applications.  However, it is important that we think clearly about where the inefficiencies are or we will solve the wrong problem.

Yes, excellent write up.  Sometimes going back to the simpler designs produces a great improvement.  The one issue, though, is that hose breaking is a bit more problematic than a wire.

Good posting on this subject.  I appreciate the comparison to electric systems and the benefits to be gained by applying hydraulics.  I have long suspected that the trend to shift as much as possible to electric positioning systems and such might not always be the best approach.

The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
