Worried about whether rewinding a motor will degrade its efficiency? Well rewind away. Findings from a study by the Electrical Apparatus Service Association conclude that motors can be rewound multiple times with no loss of efficiency, so long as it's done carefully and operators follow standard procedures. The study examined 50 to 300 hp electric motors with ratings of 1,800 and 3,600 rpm.
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.
