Über dieses Buch

This concise book focuses on the reliability of traction electrical drives. The first chapter presents the Lz-transform approach for the comparative analysis of the fault tolerance of multi-motor electrical drives with multi-phase traction motors. The second chapter then provides an estimate of the value of the operational availability and performance of a diesel–electric multi-drive propulsion system, while the third chapter introduces the concept of a more electric aircraft. Lastly, the fourth chapter analyzes the requirements for multi-phase permanent-magnet motors applicable in various aircraft systems.

1. Reliability and Fault Tolerance Assessment of Multi-motor Electric Drives with Multi-phase Traction Motors
Abstract
The Chapter presents the Lz-transform approach application to the comparative analysis of the fault tolerance of multi-motor electrical drives with multi-phase traction motors for two various maintenance strategies. Such a topology of the traction electric drive can be used in perspective propulsion system of ships, trains and aircraft, to increase the fault tolerance of electric or hybrid-electric vehicle. As a basic variant for the study, the electric propulsion system of a cargo ship for ice navigation with a total power of 5400 kW is considered. Based on the obtained results, the decision about optimal topology and maintenance strategy of traction electric drive for an icebreaking ships has been suggested.

2. Operational Availability Investigation of Multi-drive Electric Propulsion System of the Arctic Gas Tanker with Ice Class Arc7
Abstract
The chapter presents an attempt to estimate the value of the operational availability and performance of a diesel-electric multi-drive multi-motor propulsion system of a specific type of the vehicle, namely, of new icebreaker gas tanker for year-round Arctic navigation. Such kind of operations imposes specific requirements and restrictions to the propulsion system of the ship, much of which relates to the requirements on comprehensive reliability and fault tolerance. Their values largely determine the operational economic efficiency of multi-tonnage gas tankers in specific Arctic ice conditions. A special feature of considered ships energy system is also the strict requirements on availability and fault tolerance not only for the tanker’s propulsion system, but also for the uninterrupted supply with electric energy, the cooling and liquefying system of the transported gas.

3. Reliability Oriented Design of High-Speed Multi-phase Electric Generator for the Aerospace Application
Abstract
For electric generators for aerospace applications, there are stringent requirements that impose significant restrictions on design and construction. In this chapter, an analysis of the main limitations in the design of high-speed permanent magnet electric generator is carried out. The fault-tolerant multi-phase high-speed permanent magnet electric generators are designed and investigated. The research results obtained by using finite element methods are presented. In addition, experimental research is conducted and verified the theoretical conclusions. The best design of fault-tolerant electric generators is selected.

4. Fault Tolerant Multi-phase Permanent Magnet Synchronous Motor for the More Electric Aircraft
Abstract
Electric motors are the most important element in the implementation of the more electric aircraft concept, performing extremely important and crucial functions associated with the flight of the aircraft (control of critical surfaces and rudders, fuel feed and pumping, etc.). Aircraft electric motors are subject to particularly stringent requirements for reliability and resistance to external factors, as well as high requirements for the minimum mass. Therefore, multiphase permanent magnet electric motors are widely used in the aviation industry. By increasing the number of phases, reliability is significantly increased. This chapter analyzes the requirements for permanent magnet electric motors applicable to various aircraft systems, discusses and compares various motor designs, and also describes a multidisciplinary design approach, which is verified by the example of a permanent magnet electric motor for fuel pump of an aircraft engine. The chapter also describes the parameters of such an electric motor and an experimental prototype.

5. Lz-transform: Definition, Main Properties and Examples
Abstract
The Chapter presents the Lz-transform, a specific approach, which has been widely applied to Multi-state systems (MSS) reliability analyses. This approach allows one to algebraically find the entire MSS performance distribution through the performance distribution of its elements. In contradict to Universal Generating Function techniques, operated with steady-state performance distribution, the Lz-transform may be applied to dynamic MSS reliability analyses of a discrete-state continuous-time Markov process. In this Chapter, we present the Lz-transform definition, its main properties, some simple examples of applications and their numerical solution with MATLAB software.
