The predecessors of this generator were originally developed as rugged teaching aids for use by my students during a series of physics demonstrations almost five years ago.
While designing the experiment, I quickly found that commercially available generators, such as those built by Jensen or Wilesco, were not an option as they did not provide any truly meaningful power at low rpms and they were prohibitively expensive. My search for an alternative to these gave birth to what you see today in this website.
Over the years, following the input of my customers, two main product lines have been developed to accomodate distinctly different types of model engines: Generators for Model Steam Engines: Intended for use by model steam engines such as those manufactured by Jensen, Wilesco, Mamod, SEL, Fleishmann, Marklin, just to name a few.
