6.1.5Principle of working The principles for the working of BLDC motors are the same as for a brushed DC motor, that is, the internal shaft position feedback. In the case of a brushed DC motor, feedback is impl
2.Incompressible Substance
static pressure is like a spring energy per volume. In this view, Bernoulli"s equation tells us that an incompressible steady flow is like a spring-mass system; if the energy is not in the spring, (static pressure) then it"s in the motion (kinetic energy). There"s simply no other pla...

This principle also implies that there is no connection between the direction of communication and the direction of current flow, which is a mistake a lot of people make which prevents them from understanding how electronics works. This theory implies that the direction of information transmission is independent of the direction of current, which many people do not agree with ..
