New micro brushless motors from Sanyo DC Micro Motor Division feature a ceramic air bearing design and frictionless, quiet, high-speed operation. The design eliminates the need to lubricate with oil, which tends to break down over the life of the motor. A 20 mm-size motor is available, with a 14 mm-size model to come. The motor has already been applied in a rear projection television color wheel, because it runs at high speeds and temperatures and is very quiet. It is also suitable for medical applications requiring high-reliability where an out-gassing oil bearing might cause an unacceptable level of contamination.
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.
