Razvoj naprave za končno testiranje enosmernih električnih motorjev : magistrsko delo

Ratajec, Rok (author), Jankovec, Marko (mentor)

V pričujočem delu se ukvarjamo z razvojem naprave za končno testiranje enosmernih krtačnih in brezkrtačnih električnih motorjev. Namen naprave je končna kontrola v proizvodni liniji, kjer se preverijo vse funkcionalnosti motorjev pred dajanjem na trg. V delu na splošno opišemo pomen končnega testiranja v proizvodni liniji, standardizaciji in zagotavljanju skladnosti proizvodov. Opišemo pomen in vlogo znaka CE ter module za zagotavljanje skladnosti proizvoda, ki jih prinaša novi pristop. Pri zasnovi testne naprave izhajamo iz zahtev naročnika. Zasnovo mehanske konstrukcije naprave prilagodimo tako, da vsebuje vse podane zahteve in je zgrajena v skladu s standardizacijo. Na podlagi zahtev o testnih sekvencah izberemo ključne komponente. Ena izmed glavnih zahtev je izbira naprednega bremena, ki omogoča zanesljive in točne meritve pri različnih obremenitvah motorjev. Glavni del razvoja testne naprave predstavlja programska oprema. Na podlagi izbranih komponent in zahtev zgradimo program, ki omogoča avtomatsko izvajanje testnih sekvenc. Uspešno razvit program podpremo s primernim uporabniškim vmesnikom za upravljanje celotne naprave. Na koncu razvoja napravo preizkusimo tako, da na testnih motorjih preverimo delovanje vseh testnih sekvenc in preverimo ustreznost merilnih rezultatov. Ponovljivost naprave preverimo z analizo merilnega sistema MSA. Rezultat razvoja je uspešno izdelana testna naprava za končno kontrolo električnih motorjev, ki jo uporabljajo v podjetju Kolektor Ascom.

Abstract

In the present thesis, we are developing a test bench for the final testing of DC brushed and DC brushless electric motors. The purpose of the device is a final inspection in the production line, where all motor functionalities are checked before being placed on the market. This work describes the importance of end of line testing, standardisation and product conformity assurance. We describe the meaning and role of the CE marking and the modules for product conformity assurance brought by the new approach. The design of the test bench is based on the customer's requirements. The mechanical design of the test bench shall be adapted to incorporate all the given requirements and shall be built in accordance with the standardisation. Based on the requirements of the test sequences, we select the key components. One of the main requirements is the selection of an advanced load that allows reliable and accurate measurements at different motor loads. The software is a major part of the development of the test bench. Based on the selected components and requirements, a program is built that allows the automatic execution of test sequences. A successfully developed program is supported by a suitable user interface to operate the whole device. At the end of the development, the device is tested by running all the test sequences on the test motors and verifying the validity of the measurement results. The repeatability of the device is verified by measurement system analysis MSA. The result of the development is a successfully built test bench for final inspection of electric motors, which is used by Kolektor Ascom.
