Laboratory Testing of Collector Characteristics

The main idea of the project is to increase the service life (resource) of electric brushes of electric machines (additionally by 30–50 %), depending on their design. The recommended electric brush is fundamentally different in design and service life from the existing brushes. This electric brush is a composite brush, while the existing commercially available brushes are one-piece. Chemical composition and proportions of components of composite electric brushes, their sizes do not differ from serial ones. The design parameters of the electric machine and brush holder also remain unchanged. This confirms the absence of the slightest technological risk in the operation of the new type of electric brushes. Let us briefly consider the main content of technical diagnostics. Technical diagnostics studies methods of obtaining and evaluating diagnostic information, diagnostic models and decision-making algorithms. The purpose of technical diagnostics is to improve the reliability and resource of technical systems.
