  • Vibration analysis of vacuum cleaner motors
    Tavčar, Jože, 1966- ; Duhovnik, Jože, 1948-
    Once a product is developed and its manufacture begins, its level of excellence immediately starts decreasing due to other competitive products on the market. Its life on the market can be prolonged ... by continual product improvements. A longer product lifetime also increases its profitability, because the development of a new family of products is associated with considerable costs. The paper presents product re-engineering using an example of a vacuum cleaner motor and its positioning in the product development cycle. The development of vacuum cleaner motors (motor and turbine assembly) is progressing in the direction of increasing the number of revolutions and decreasing their mass and volume. The performed analysis of vacuum cleaner motor construction indicated several possibilities for increasing the number of revolutions. The basic problem concerns the influence of individual components on critical speed. The paper assesses the applicability of individual methods for the analysis of natural frequencies; the results are summarized in the form of engineering design rules for vacuum cleaner motors. The analysis was performed for an example from current manufacturing practice.
