By using rare-earth magnets, engineers maximized the torque in Maxon's new RE series of motors. The motors measure just 15 mm (0.59 inches) in diameter and 22.5 mm (0.86 inches) in diameter and weigh 20 g (0.71 oz). They can deliver 300 mNm (42 oz-in) of continuous torque with a maximum speed of 11,000 rpm and maximum efficiency of 73%. Each applies Maxon's patented rhombic moving coil design to provide long life, low electrical noise, fast acceleration, and high efficiency. Maxon Precision Motors, Product Code 4170.
A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
