The purpose of the study was to cover the impact of variable frequency drives in to-day's industry. A partial aim was also to study perspectives regarding the advantages and disadvantages of the variable frequency drive, its function based on sustainability, production efficiency and demand. The study was based on a qualitative research method, and the empirical material has been based on six semi-structured interviews from industries that currently use variable frequency drives. The results and parts of the study’s purpose were analysed based on previous research and theoretical perspectives. The results mainly show that variable frequency drives contribute to energy savings in our industries. Energy saving was also seen as one of the component's main ad-vantages, followed by the fact that it was considered cost effective in relation to its long lifetime. The cost and complexity of the product were identified as the compo-nent's disadvantages. In relation to sustainability, variable frequency drives mainly match with two of the goals in Agenda 2030, sustainability goals 9 and 12. In this regard, the variable fre-quency drives energy saving is central to the product from a sustainability point of view. In relation to production efficiency, variable frequency drives were found to be more energy efficient, and for that reason affect the process flow for the better, which indicates increased production efficiency. The component was considered as a flexible production solution that enables flow control, as well as maintaining a con-sistent quality of the production flow. Based on the results of the study, the demand that exist today for variable frequency drives only seems to increase. It is stated that there is a great demand today, while depending on the nation, it only seems to be expanding.
