MAHLE develops the EESM rotor and their brushless excitation system ... to be reduced by more than 40% versus a permanent ...

As an alternative, we can make use of a three-phase brushless permanent magnet motor's back-electromagnetic force (EMF). As I wrote last month, back-EMF is a voltage generated by the interaction ...

Your grandmother means well. But by the time she figures out something’s a fad, it is old news. So maybe you got a fidget spinner in your stocking this year. Beats coal. Before you regift it to ...

Permanent Magnet Synchronous Motors (PMSM ... However, brushed DC motors have some notable disadvantages compared to newer brushless motors: • Lower efficiency - Repeated friction of the ...

Three-phase brushless motors, mainly AC induction (asynchronous) and permanent magnet synchronous, are known for their high efficiency, reliability, low maintenance, low cost and silent operation. The ...

Permanent magnet synchronous motors (PMSMs) are AC synchronous motors that receive field excitation by permanent magnets. These motors have sinusoidal back-EMF and are similar to brushless DC (BLDC) ...

Here’s [Tom Parker] showing off a brushless motor gimbal stabilizer for his GoPro camera. We saw a similar project a couple of weeks back that featured a 3d printed quadcopter mount.
