Brushless motors and controllers (PoD)

In the past few years, brushless motors and controllers have made an unparalleled triumphant advance everywhere in model building - and in many other areas as well. In the meantime, they are not just an alternative to brushed motors, but have almost completely pushed them out of the market in many places. Roland Büchi explains how brushless technology works and what the reasons for its success are. Applications of various controllers and motors of different power are discussed as practical examples.
