Master maker, cartoonist, author, and artist Tim Hunkin spent his pandemic downtime producing a series, “The Secret Life of Components”, to introduce designers and builders to the bits and pieces he uses in his fanciful machines. This is a practical builder’s guide to electric motors, describing the advantages and disadvantages of DC, AC induction, synchronous, brushless DC, steppers, and “smart” motors. The explanation of how back EMF causes a DC motor to adjust its current consumption with the load and can be used as a brake is brilliant.
