The study of an open innovation model for the industrial chain of electrical steelTsai, Song-jau 18 July 2009 (has links)
Resources limitation in corporation renders the need for open innovation to advance their competence. Open innovation suggests utilization of outside resources can improve internal innovation and the internal IP¡¦s shall extend their usage beyond the boundary of firm to reach maximum benefit. The most remarkable open innovation paradigm in the history was IBM¡¦s release of its PC core software to give impetus to information revolution. Recently, Proctor and Gamble adapts the open innovation model and seek for external ideas which account for more than 50% of innovation of the company. Despite its phenomenal success in several cases, open innovation is not rooted in many industries. This study would investigate on the feasibility of the application of open innovation model to the electrical steel (ES) industry chain.
Electrical steel is one of the most dedicated products in the steel industry. It¡¦s the crucial material in motors and transformers. China Steel holds more than 7% of the market share of ES of the world and influences the local motor markets greatly. Taiwan was once recognized the most important manufacturing base of small motors in the world. Nevertheless, motor industries in Taiwan have suffered huge decline in the past 20 years due to migrating to China whose economy reform provides much more attractive investment environment by lower wages and other operation costs. Until recently, soaring energy prices and tighter environment protection measures recently create growing worldwide need of high efficiency motors and provide new opportunity for the motor industry in Taiwan. Being the sole supplier of high quality ES in Taiwan, how China Steel takes advantage of this opportunity and enhances its competiveness is the main interest of this study.
This study focuses on the industry chain of ES in Taiwan by systematic survey on its market, technology, and man power to understand its strength, weakness, facing threat and opportunity. An open innovation model is proposed and implemented in the ES industry chain by establishing a new platform, introducing new management paradigm and creating new efficacy indices. The model potentially allows continuous technology support to the chain and creates a sustainable business environment. Its feasibility is further discussed as to forming a healthy industry chain.
The fast growing trend of global production volume of ES indicates the ever-increasing demand in the motor industry. The consumption rate of ES in Taiwan however did not appear the same order of growing rate as the rest of the world. This may imply the motor industry in Taiwan still faces tough challenge from China. Advancing and upgrading in design and analytical capability along with the competitive manufacturing bandwidth is the only solution to regain the competiveness. The proposed open innovation model is anticipated to promote the value of the ES industry chain, which in turn will increase China Steel¡¦s domestic market share for high quality ES.

Impacto da utilização de motores de alto rendimento e sua aplicação no leilão de eficiência energética. / Impact of the use of high performance engines and its application in the auction of energy efficiency.Micerino, Fabio José 14 May 2012 (has links)
O trabalho apresentado tem como objetivo principal pesquisar e demonstrar através de simulações as implicações da utilização de motores de alto rendimento com viés de Eficiência Energética. Além disso, pretende-se estabelecer uma ligação entre o uso eficiente da energia com a possibilidade dos leilões de eficiência energética virem a se tornar uma realidade no Brasil. É de fundamental importância que se tenha a preocupação com sistemas de conservação de energia e não somente com novas fontes de geração. A eficiência Energética vem ganhando cada vez mais espaço no setor elétrico, se tornando muito mais que um indicador, mas também uma forma de tornar o sistema mais robusto e capaz de suprir deficiências por problemas estruturais. Procurou-se demonstrar o cenário atual da matriz energética atual, conceituar leilões de eficiência energética e os certificados brancos que é um subproduto deste. Por fim, realizou-se várias simulações estudando a substituição dos motores de alto rendimento e os ganhos técnicos e financeiros atrelados aos leilões de eficiência energética. Além disso, foi demonstrado também o impacto da utilização dos motores de alto rendimento em leilões de eficiência energética por segmentos da indústria brasileira. / The present study has as main objective the analysis, through simulations, of the implications of the use of energy efficient motors with a bias of energy Efficiency. In addition, we intend to establish a link between the efficient use of energy with the possibility of auctions for energy efficiency become a reality in Brazil. It is also important to have concerns with energy conservation systems and not only with new sources of generation. Energy efficiency is becoming an increasingly common concern in the electricity sector, being much more than an indicator but also a way to make the system more robust and capable of mitigating deficiencies which occur by structural problems. In this work we tried to present the current energy scenario and define the energy efficiency auctions as well as its byproduct, the white certificates. Finally, we carried out several simulations studying the replacement of common electrical motors by high efficiency ones in order to analyse the technical and the financial gains linked to energy efficiency auctions. In addition, we also demonstrated the impact of the use of high efficiency motors by sectors of brazilian industry in the energy efficiency auctions.

Définition de nouvelles structures de circuits magnétiques de machines AC utilisant des tôles à grains orientés / Definition of novel structures for magnetic circuits of AC motors using grain oriented steel laminationsLopez, Samuel 15 March 2011 (has links)
Le travail présenté porte sur la définition et le développement d’un circuit magnétique pour moteurs à haut rendement de faible et moyenne puissances. Il est réalisé avec des tôles à Grains Orientés (GO) non-segmentées. Des expérimentations réalisées en champ unidirectionnel, destinées à comparer les caractéristiques globales de la structure GO à celles obtenues sur un assemblage classique composé de tôles à grains Non-Orientés (NO), permettent de conclure quant à l’efficacité de l’association proposée en termes de pertes fer. Des investigations au niveau local, accompagnées d’une modélisation numérique, conduisent à une analyse de la répartition interne du flux magnétique dans la structure, permettant de l’optimiser. Cette technique d’assemblage est ensuite testée en champ tournant sur des moteurs statiques. Les performances obtenues, sont de nouveau comparées à celles relevées sur une maquette NO. L’étape finale consiste à tester le principe développé sur des moteurs à induction réalisés avec la configuration GO. Diverses caractéristiques sont relevées ou estimées (norme CEI) et comparées à celles de la machine NO d’origine. L’efficacité de la structure GOse traduit par une réduction notable des pertes fer, notamment statiques, conduisant à accroître sensiblement le rendement global de la machine. / The work presented is focused on the design and development of a magnetic circuit for high efficiency motors of medium and small powers. It is built with non-segmented laminations of Grain Oriented (GO) steel. Experimentations on magnetic circuits excited under unidirectional magnetic field are performed. Such tests aim the comparison of the GO structure global characteristics with those of a classic one composed of Non-Oriented (NO) steel, allowing seeing the superiority of the GO structure in terms of iron losses. Local experimentations, followed by a numerical model, allow the analysis of the local distribution of the magnetic flux within the structure, leading to its optimisation. Such technique of assembly is then tested under rotational magnetic field. In that context, several experimentations are performed and its performance is compared with the one of a NO prototype. The final stage consists in testing the developed structure in induction motors built withthis GO assembly. Several characteristics are measured or estimated (IEC standard) and compared with those obtained on the initial NO motor. The GO structure efficiency leads to a remarkable reduction of the static losses, allowing the increase of the global efficiency of the motor.
