Commutator motors and vacuum cleaner motors represent an important part of Domel's production. To ensure their successful operation, the quality of the commutators is crucial. To guarantee this quality, commutators are tested for burst, with the aim of simulating their performance under high loads. The existing testing device causes numerous issues, such as uneven results and insufficient reliability, which led us to develop a new device that allows for easy and repeatable testing while fulfilling all testing requirements. The new device is designed to enable faster execution of tests and more precise analysis of results, contributing to the improvement of the entire process. This thesis presents the complete process of constructing individual components and the final assembled device. The device was tested by evaluating serial commutators, allowing us to evaluate their quality through three different tests, for which we defined a testing procedure. In addition, we also confirmed the suitability of the device concept, its durability, and the repeatability of testing during multiple test executions.
