In this comprehensive tutorial, you will discover the step-by-step process to construct a Magnet Motor Generator capable of ...

This is a small motor made from simple household supplies. A battery pushes current through a coil of copper wire under the influence of a permanent magnet. The coil spins freely when operating.

Thankfully, they do because the laws of physics do not change. Even so, despite their simplicity, selecting a dc motor for an application can still be a daunting task.

When selecting a Coreless Brush DC Motor for an application, or when developing a powered prototype, there are several basic motor physics principles which must be considered to produce a safe ...

Conservation of energy The conservation of energy is a basic principle of physics—energy cannot be created nor destroyed. When something (such as a mass) is moving or rotating, it accumulates kinetic ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...
