What motors are in drills?
There are two main types of motors used in most applications: DC (or universal) motors and induction motors. DC motors are much easier to understand, so I will start with those. Universal motors are used in most hand held power tools, such as drills, routers, jigsaws and sanders.
Can I use a drill motor as generator?
Things You’ll Need Use the motor from an old drill to power a battery charger or small appliances. Re-purpose a cordless drill to create a DC generator. Using the motor from a cordless drill you can build a battery charger or an AC power source. By turning the motor in reverse, electricity is created rather than used.
Why brushless motors are better?
More energy-efficient. Because there are no brushes rubbing against anything, no energy is lost due to friction. That means brushless motors are more energy-efficient than brushed drills and can run on batteries for up to 50 percent longer.
Is a brushless motor better?
In summary, brushless motors are better than brushed units. Users can take advantage of reduced maintenance, improved efficiency, reduced heat and noise. The brushless motors are synchronous units with one or more permanent magnets. Power tools with a brushless motor are now considered high-end products.

How do you regain residual magnetism?
To restore the small amount of residual magnetism necessary to begin voltage buildup, connect a 12 volt battery with a current limiting device to the exciter field while the generator is at rest, as follows: 1. Remove exciter field leads F+ and F- from the voltage regulator.
