the intend is to allow a deeper exploration possible through the data analysis and perhaps even some simple mathematical model equation to curve fit the data.

exactly what to do, i have not figure out yet.

the feature was ported from the AC generator as there is a sine and cosine curve for the emf and current.

Dc motor i need to think what to do in order to deepen the appreciation of the physics through mathematical analysis of the data.

any suggestions is welcome!
