kaudse vektorjuhtimisega säilitatakse õhupilu magnetvoo konstantsus ka siirde- talitlustes. Nende kahe meetodi erinevus tuleneb toitemuunduri juhtimise ise- ärasustest. Libistuse skalaarjuhtimise korral muudetakse korraga muunduri kõigi faaside pinget ja sagedust, kaudse vektorjuhtimise korral juhitakse õhupilu magnetvoo ja staatorivoolu vektorite vahelist faasinurka. Selleks arvutatakse vastavas arvutusplokis (vt joonis 6.8) staatorivoolu ristkomponendid ids ja iqs ning rootori libistuskiirus s. Joonisel 6.8 on kujutatud kaudse vektorjuhtimisega asünkroonajami plokkskeemi. Joonis 6.8 6.4.3. Loomulik vektorjuhtimine. Loomulik vektorjuhtimine põhineb hüpoteesil, et asünkroonmootori võib taandada ekvivalentseks alalisvoolumootoriks ning et teda kirjeldavad alalisvoolumootori omadega sarnased võrrandid.

someone can come along and show them that a new idea has more merit. They are more concerned that the new idea works to solve a problem or achieve a goal than they are with being right themselves. ■ THREE QUALITIES OF GENIUS Geniuses have been studied extensively over the years. One of the most remarkable conclusions the experts have arrived at is that ge- niuses are not necessarily people with extraordinary high IQs. They are often ordinary people who use their intelligence in a superior way compared to average, or even smarter, people. What this means is that you can function at genius levels if you learn to think the way that geniuses do. Geniuses seem to have three characteristics in common, each of which you can develop and make into a regular part of your thinking. First, geniuses seem to have open minds. They are curious, ques-
