Abstract: [slo] [eng]
Táto práca pojednáva o problematike tvorby hluku v elektrických točivých strojoch, motoroch. Najprv si objasníme čo vlastne je hluk a zvuk, jeho vlastnosti, jeho šírenie v strojoch. Potom si preberieme možné zdroje hluku v elektrických motoroch a potom možnosti zníženia hluku. Pre overenie teórie uvedenej v tejto práci vykonáme meranie hluku na asynchrónnom elektrickom motore. Ďalej ešte prevedieme meranie pracovnej charakteristiky stroja. Nakoniec popíšeme jednotlivé merania. This work discusses the problem of generating noise in electrical rotating machines, engines. First we explain what noise and sound is, its characteristics, its distribution in machines. Then we discuss the possible sources of noise in electrical motors and the possible reduction of noise. To verify the theory mentioned in this work, we will execute a noise measuring on an induction engine. Further we realize a measurement of the operating curve of the machine. Finally, we describe various measurements.
Keywords: bearings; frequency; induction engine; microphone; noise; noise-meter; sound power; Sound pressure; vibration; waves.
