Abstract
Orgulje kao jedan od najkompleksnijih ljudskih izuma sadrže mnogo elemenata, od kojih je jedan elektromotor koji služi za pokretanje centrifugalnog puhala. Elektromotor i puhalo zajedno čine sustav dovoda zraka koji je ključan dio instrumenta. Uslijed zagrijavanja elektromotora tijekom rada, toplina s kućišta elektromotora prenosi se na kućište puhala, a preko puhala toplina ulazi u instrument. Zbog zagrijavanja zraka mijenja se visina tona svih svirala u orguljama uzrokujući probleme glazbenicima tijekom izvođenja glazbenih skladbi. Za analizu ovog problema korištena su mjerenja izvršena na dva instrumenta različitih veličina. Mjerenja su pokazala da je utjecaj toplinskih gubitaka elektromotora na akustične karakteristike veći što je instrument manjih dimenzija i kompaktnije građe. Na kraju rada predstavljena su moguća rješenja problema kroz analizu prednosti i nedostataka svakog rješenja pojedinačno.
Abstract (english)
Pipe organ is one of the most complex human inventions. They are comprised of many elements. One of them is electric motor which is used to power the blower. Electric motor and blower make air supply system, a crucial part of the instrument. During the operation of electric motor, heat energy losses are transfered from the electric motor's case to the blower's case that heats up the air coming into the instrument. Heated air causes pitch change in all of the pipes inside the organ and consequently problems to musician performing music. This problem is observed and analysed using measurements from two differently sized pipe organs. The measurements showed that the effect of electric motor’s heat energy losses on acoustic properties are more perceptible on smaller, more compact made instruments. At the end of this work possible solutions to this problem were presented and individually analysed.
