Aim: Establishment of preconditions for the introduction of a switched reluctance motor into the system of traction drive of an electric rolling stock by improving the performance of the bearing unit. Methods: Calculations were carried out using the finite element method. Results: It was found that the calculated values ​​of force of a one-way magnetic attraction applied to the bearing unit are tens of times higher than the permissible values. The result is accelerated wear and failure of the bearings. An algorithm is proposed which takes into account the influence of one-way magnetic attraction forces in an uneven air gap. Conclusion: The algorithm makes it possible to change the production cycle and improve the consumer quality of the switched reluctance traction motor.

The Subject

The subject of research is the traction switched reluctance motor for transport systems with uneven air gap. The calculation of the forces of one-way magnetic attraction during displacement of the rotor is carried out. It has been shown that these forces reach high values and exert an influence on the bearings leading to their premature wear. Measures are proposed to reduce the influence of one-way magnetic attraction forces and to increase the reliability of the bearing unit.

<p>This paper proposes a linear switched reluctance motor (LSRM) to replace the conventional serving that is used in food and beverage (F&amp;B) applications such as a pack of sushi and carbonated drinks. This conventional method is no longer practical as it requires a lot of space which will affect costing and productivity. It’s also has another disadvantage, in which it needs frequent maintenance of the rotational motor, gear, and limit switches. Therefore, this research is about the design and analysis of linear switched reluctance motor (LSRM) for F&amp;B applications. The main objective is to design a LSRM and the finite element method (FEM) is used to simulate the result. The result showed that the 24s/16p was the best model for linear switched reluctance motor (LSRM) design. The model had average force (F_avg) of 28.36 N for input current (I) of 1A. To conclude, this paper<br />provides a guideline in designing the LSRM for F&amp;B application.</p>

The paper discusses the development of an expert system for diagnosing electric traction motors of rolling stock. The diagnostic parameters of the electric traction motor commutator-and-brush assembly, being the input linguistic variables of the fuzzy model, were selected with the use of graphoanalytic model. A fuzzy mathematical model and a fuzzy neural network for comprehensive indicator of quality of mechanical machining implementing the Takagi — Sugeno fuzzy inference algorithm were developed. The authors confirmed the practicability and the adequacy of the previously proposed comprehensive indicator of quality of mechanical machining for assessing the technical condition of the electric traction motor commutator-and-brush assembly. The studies carried out allowed creating an element of intelligent expert diagnostics system that enables a comprehensive assessment of technical condition of electric traction motor.

The paper considers a new version of IRIS ISO/TS 22163:2017 standard in relation to the quality of repair of complex equipment in the railway industry. It is shown that the new version of ISO/ TS 22163:2017 standard provides for the need of organizations to conduct risk analysis and accounting in their work. The authors propose to consider as an example a well-established analysis of the types and consequences of potential defects in FMEA process. The use of FMEA analysis made it possible to consider the significance of various risks of the quality of traction rolling stock repair, as well as to establish the importance of quality control operations for impregnation of a traction motor.

Abstract The subject of the research is a traction switched reluctance motor with an uneven air gap. The main purpose of the work is to determine the forces of one-way magnetic attraction, evaluate and analyze these forces, develop measures to reduce the forces to an acceptable value. In the article, the forces of disbalancement and the forces of one-way magnetic attraction are considered in the relationship. The finite element method was used to determine the main parameters of the switched reluctance motor. The studies were carried out for two idealized variants of the location of the rotor rotation axis. In the first case, the axis of rotation is combined with the axis of symmetry of the stator. The second option considers the case of displacement of the axis of rotation together with the axis of symmetry of the rotor. It is determined that the resulting force of one-way magnetic attraction with an uneven air gap reaches significant values and significantly exceeds the permissible values. An algorithm for calculating the characteristics of a switched reluctance motor is proposed, which takes into account the tolerances for the manufacture of its design elements. The algorithm allows you to adjust the requirements for the bearings used, ensure the required level of reliability of the traction switched reluctance motor (SRM) and predict the level of vibration and noise.

The analysis of power steering which used on modern rolling stock is carried out. Their main shortcomings are identified. Given the requirements for the steering of trolleybuses, a solution to increase its efficiency is proposed. Based on the developed mathematical model and functional diagrams of the trolleybus steering system with a electric power steering based on rolling rotor switched reluctance motor, a simulation model of trolleybus steering was created using the Matlab Simulink package. The peculiarity of the simulation model is taking into account the mass and size characteristics of the rolling stock, the parameters of the suspension of the steered axle, the impact of the road surface and the speed of the trolleybus, changes in the parameters of the electric motor magnetic system during operation. The rolling rotor switched reluctance motor which is offered for use as the electric power steering of the LAZ E183D1 trolleybus is calculated. The calculation of the magnetic system of the engine by the finite element method with the subsequent approximation of the obtained results is carried out. With the help of the developed simulation model the simulation of the trolleybus steering system with electric power steering based on rolling rotor switched reluctance motor was performed. Time diagrams of transients in the trolleybus steering system are obtained and their processing and analysis are carried out.
