In the realm of survivalism and long-term self-sufficiency, efficiency and reliability are the main traits we want to look for. Every single component, from tools to vehicles, must be optimized for longevity and minimal resource consumption. This is the way you save money, space, and time.
Here is where brushless motors come into play, offering a significant advantage over traditional brushed motors in many applications.
Being the son of an electrician, I’ve been involved with electric motors my whole life. These will be there for a long time, trust me, even after the internal combustion engine is nothing but a memory of the past. Sure, some things have to change in the first place: modern (mechanical) diesel and seed oils are a GREAT combination, not because of the fancy, obsolescence-programmed electronics. When I say “modern” regarding the technology in diesel engines, I talk about the alloys, optimized geometrical designs, and coatings. But that is for a different article.
As it´s to be expected, many readers who are not familiar with technical aspects will ask about the difference between these two types of electric motors. This is not easy to explain without a basic understanding of how an electric motor works. There are tons of videos about this, so please take a look at one of them if you feel like it to get a better idea.

Nice insight Jose thanks! Good to keep spares like little bearings for the power tools that are usually the first to break and spare brushes for brushed motors. Carbon brushes are also easy to shape from a piece of graphite or from other bigger brushes, with some skills and tools this can be done quite easily as carbon graphite is soft material and sands down easily. Also learn how to use your multimeter and you can find most faults, takes time and practice!
