Maxon Precision Motors' new "RE" series of motors use powerful rare-earth magnets and graphite brushes to eke out the highest torque possible in a 25-mm diameter package, Maxon says. As with the company's other motors of this design, the RE series uses a patented rhombic moving coil design to deliver long life, low electrical noise, fast acceleration, and high efficiency. The ironless rotor allows for zero cogging and simple, accurate control. Weighing 4.6 oz and measuring 2.1 inches long, the 25 mm motor is rated at 20W. Maximum speed is 11,000 rpm, and maximum efficiency is 87%. Maxon Precision Motors, Product Code 4216.
In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
