The master's thesis is focused on the development of electromechanical drive for a vacuum cleaner with water filter, and related requirements for industrialization of the product. The industrialization does not only meet client demands but also gen-eral regulations and standards that define suitability of the product for sale on world markets.
Electromechanical drive for vacuum cleaner with rated power 720 W, consists of an electronically commutated motor (ECM) and controller that provides reliable motor operation and functionality of the whole product.
The first part of thesis explains product specifications which are result of cus-tomer's requirements and possible technical solutions according to manufacturer technology. The use of ECM technology is justified by longer life expectancy and it reduces release of graphite powder in comparison to single phase AC motor. The requirement for low product price also delegated the system design that allows the use for both 120 V/60 Hz and 230 V/50 Hz voltage systems.
The electronic circuit of the vacuum cleaner consists of two parts, the filter stage and power converter stage. Their functions are described in detail through schematic diagrams, and components calculations, such as a choke for passive power factor correction. Additionally other parts of controller are described – rectifier cir-cuit, power stage, control unit, power supply, input /output stage and current protec-tion for electric brush.
On the end of the paper there are results representing life expectancy tests, functionality tests, thermal and mechanical testing, for which the dedicated electrical circuits were also designed.
