ANALYSIS OF THE SYNCHRONOUS MOTOR SM4P

Podjetje Firšt d.o.o. uporablja v svojih izdelkih tudi lasten enofazni sinhronski motor male moči SM4P z rotorjem iz trajnega magneta. Od izdelkov podjetja se zahteva zanesljivo delovanje in primeren zagonski ter omahni moment. Te lastnosti so pri omenjenem motorju dosežene tudi s posebno sklopko med rotorjem in gredjo. Namen dela je bil zasnovati in izdelati merilni sistem, ki bo omogočal potrditi smiselnost sklopke in analizirati delovanje predvsem v fazi zagona. Z njim bo mogoče izvajati dinamične in statične meritve ter sistematično ovrednotiti vplive možnih izboljšav na zagon motorja. Na koncu so podane še nekatere ideje in možnosti nadgradnje merilnega sistema.The Company Firšt d.o.o. uses also own small single-phase synchronous motor SM4P with permanent magnet rotor in its products. Form company products reliable operation and adequate breakaway and breakdown torque is expected. These characteristics were achieved at this motor with a special clutch between rotor and shaft. The idea of our work was to design and put together a measuring system that will make possible to analyze startup functioning and approve usage of the clutch. It will be possible to perform dynamic and static measuring with it, including systematic evaluation of influences of possible improvements to the motor startup. At the end we added some ideas and possibilities to measuring system upgrade
