# Industrial Design of Electric Machines Supported with Knowledge-Based Engineering Systems
###### Abstract
This implementation is one of the most complete found in literature; however, the roadmap showing how can you achieve the development of such knowledge-based system is not described. [PERSON] et al. [8] propose a knowledge-based software architecture scheme structuring the knowledge in different layers depending on the knowledge source for the electric machine domain. Ongoing research [9; 10] shows promising new concepts of KBE methodologies towards the manufacturing process of electric machines. The authors acknowledge the importance of integrating new technologies to support the development process and reuse components. This paper intends to reduce the gap between designs found in literature and industrial designs. The former more focused on optimizations and the latter on finding reliable solutions based on reusing previous designs. It is worth remarking that the electric machine industry has evolved from having their developed computational systems to currently incorporating commercial numerical computation solutions software. This transition requires developing new procedures and software applications that could be linked to commercial ones to speed up the definition of the problem, solving, and post-processing results. Current CAE/CAD suites offer automation of processes among third party software through programming interfaces, thus allowing faster execution of repetitive interactions with other software packages. Due to the large investment required, developing a KBE system coping with all the company's needs is unaffordable for small and medium electric machine companies [11]. This paper aims to provide a solution to reduce the required investment gap. To do this, it proposes a solution combining a KBE application with commercial software tools typically found in the industry, such as requirement management, product data management, and design software tools. Aside from containing the knowledge base with designers' know-how, the KBE application also commands the different steps following a series of standardized macro-processes and a set of micro-processes belonging to the specific company. In previous work [12], we proposed a three V-model methodology adapted by merging the Verein Deutscher Ingenieure (VDI) 2221/2206 standards and decomposed them into concept, component, and industrial V-cycles. The scope herein presented is to begin the development of the KBE system with the industrial V-cycle, in other words, from standardized parts (dies, shafts, housing, etc.) that guarantee reliability to the company. This proposal arises because the standardization of a part such as the tooling die is a process that could require knowledge from an external manufacturing company that also has their know-how, therefore complicating the implementation in case the knowledge cannot be shared. This article aims to define a framework for implementing a KBE system for the electric machine domain that can serve as a guideline for KBE system developers and electric machine designers. Compared to KBE literature for electric machines, the scientific contribution lies in the unified development of a KBE application that integrates commercial software (SW) through a knowledge base generation system, optimizing its development using standardized processes. The KBE system consists of the following novel elements: (1) a knowledge base generation process based on MOKA methodology (MOKA stands for Methodology and software tools Oriented to Knowledge based engineering Applications); this methodology implementation is new regarding the electric machine domain.
