Historically, generator inspections require rotor removal (Figure 1). There’s a significant level of risk during this process due to possible generator damage during the disassembly, and it also ...

We tested 20 solar generators to find the most versatile devices that can provide emergency backup power and fuel off-grid activities. Three came out as the best.

[The LED Artist] often found a need for a relatively high voltage (100 to 200 Volt) but low current DC power supply, and it turns out that a small HV generator that uses a single AA cell only took ...

Testing DC supplies can be done in many ways, from connecting an actual load like a motor, to using a dummy load in the manner of a big resistor. [Jasper Sikken] is opening up his smart tester for ...

Design engineers know that both brush DC and brushless DC (BLDC) motors can operate as generators, but many tend to avoid running brushed DC motors in generating mode because they believe it is ...

A researcher in Russia thinks he has a way of generating power from wind turbines and other rotating devices that is super-efficient thanks to the elimination of any intervening power conversion ...
