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 ...

[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 ...

As covered in my previous blog post, all diesel-powered generators should be loaded to at least 30% of their standby nameplate rating when exercised during their monthly test. If the connected load ...

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 ...
