on video 3 simple inventions with DC motor

In this video I will make 3 simple inventions. The first is the self-excitation of a car alternator using a capacitor bank with DC motor as the driving machine. The second uses the BLDC brushless motor from an old washing machine as a low-speed electrical generator. The third is to turn a 12v bicycle starter dc motor into a high current electric generator.

DC motors can be found in many portable household appliances, automobiles, and different types of industrial equipment. In this video we are going to understand how DC motors sold in the market work and are made. Let's start with the simplest possible DC motor. It looks like this. The stator provides a constant magnetic field, and the armature, which is the rotating part, is a simple coil. The armature is connected to a direct current source by a pair of collector rings. When current flows through the coil, an electromagnetic force is induced on them, according to Lorentz's law. The reel will therefore begin to rotate.
