It seems that any buyer of motors, especially those that use a lot of power, would of course consider the efficiency of a motor as a major parameter in making the selection of which motor to select. This is true because in most cases the cost of power to run the motor over it's lifetime is far greater than the initial purchase price. The very rare exception is motors that are very seldom operated, where perhaps reliability and size are more important than efficiency.
So while uniform test procedures would be a worthwhile rule to enforce, as well as truth in advertising and labeling, it wo8uld seem that the market would enforce the production of only the most efficient motors. Of course, there may be something else not mentioned in the discussion, such as a tendancy for some offsore sources to provide completely false information about their products, the most obvious is overstating wire sizes. Finding a spool of wire marked as number 12 and finding that it is actually much closer to what would be number 15 is not a nice surprise.
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
