Abstract:V diplomskem delu je opisna razvoj razširitvene plošče za nadzor parametrov brezkrtačnih enosmernih elektromotorjev – BLDC motorjev. V začetku je predstavljena sama zgradba in različne vrste BLDC motorjev in teoretična osnova delovanja in možni načini krmiljenja. Po pregledu teorije sledi pregled razširitvene plošče, postopek načrtovanja, izbira merjenih fizikalnih količin, opis izbranih komponent na razširitveni plošči, razlaga programske kode in opis postopka zasnove ohišja in možne montaže na avtonomni kmetijski robot. K končnem delu so predstavljeni še rezultati testiranja in zaključne ugotovitve. Končni produkt diplomskega dela je razširitveno elektronsko vezje, ki izvaja meritve električnega toka, ki teče do posameznega motorja avtonomnega kmetijskega robota. Meritve izvaja s 16-bit resolucijo, ki poda dovolj zanesljive podatke, dovolj hitro in nepotrebno ne obremenjuje krmilnika. Z natančnejšo izbiro komponent bi bilo mogoče končno različico vezja še nekoliko zmanjšati, da bi bila mogoča pritrditev znotraj ohišja avtonomnega kmetijskega robota, prav tako pa tudi zmanjšati ceno izdelave. Po pregledu sorodnih produktov na trgu nisem zasledil produkta, ki bi bil zelo podoben, ampak je pogosto to opravljeno na samem krmilniku, kar prinaša neko inovacijo v smislu dodatka k krmilnikom BLDC motorjev, ki te funkcije ne omogočajo.

Title:Development o fan expansion board for monitoring BLDC motor parameters
Abstract:The diploma thesis describes the development of an expansion board for monitoring the parameters of brushless DC electric motors - BLDC motors. In the beginning, the structure and different types of BLDC motors are presented, as well as the theoretical basis of operation and possible control methods. The theory is followed by the specifications of the expansion board, the design process, the selection of measured physical quantities, a description of the selected components on the expansion board, an explanation of the program code and a description of the housing design and possible assembly on an autonomous agricultural robot. In addition to the final part, the test results and final findings are presented. The final product of the diploma thesis is an expansion circuit that performs measurements of the electric current flowing to an individual motor of an autonomous agricultural robot. Measurements are performed with 16-bit resolution, which provides adequately reliable data fast enough and does not unnecessarily load the controller. With a more precise selection of components, the final version of the circuit could be further reduced to allow it to be mounted inside the housing of an autonomous agricultural robot, as well as reduce the cost of manufacture. After reviewing related products on the market, I did not find a product that would be very similar, but often this is done on the BLDC motor controller itself, which brings some innovation in terms of adding to BLDC motor controllers that do not include this feature.
