Debalans oz. masna neuravnoteženost telesa povzroča sile in vibracije v podporah, ki močno vplivajo na delovanje in življenjsko dobo naprave. Zaradi povečane elektrifikacije vozil, se pojavlja vedno večja potreba po elektromotorjih z visokimi vrtilnimi frekvencami in posledično diagnozi njihovega dinamskega obnašanja. V okviru magistrskega dela smo zasnovali enostavno preskuševališče na prožni podpori. S pospeškomerom smo merili vibracije na vsaki izmed podpor -- ležajnih mestih in z merilnim sistemom zajemali časovni signal pospeška. Signal smo nato s kodo v programskem jeziku Python tudi obdelali. Z metodo dinamičnega balansiranja smo določili debalans na vsaki izmed merjenih ravnin. Mass imbalance of the body causes forces and vibrations in the supports, which strongly influence the operation and lifetime of the device. Due to the increased electrification of vehicles, there is an ever-increasing need for high-speed electric motors. Consequently, there is also a need to diagnose their dynamic behavior. Within the master's thesis, we designed a simple balancing device on a flexible support. We used accelerometers to measure the vibrations at each of the supports-bearing locations. With the measuring system, we captured the acceleration time spectrum. The signal was then processed with code in the programming language Python. Using the dynamic balancing method, we determined the unbalance on each measured plane.
