Abstract
Patente de Invenção: <B>"MáQUINA ELéTRICA, NúCLEO LAMINADO E PROCESSO DE MONTAGEM DE MáQUINA ELéTRICA''<D>. A presente invenção refere-se a uma máquina elétrica tendo um estator dotado de ranhuras nas quais são fixados de forma inédita os respectivos elementos de enrolamento. O referido estator geralmente compreende um núcleo laminado, que é também denominado pacote de chapas. Os ditos enrolamentos são, via de regra, concretizados como barras eletricamente conectadas entre si, que podem estar também ligadas às conexões de saída do respectivo enrolamento. Para o presente invento, as referidas barras passam por um processo de aplicação de resina sendo usualmente chamadas de barras polimerizadas. A fixação das ditas barras polimerizadas nas respectivas ranhuras do núcleo laminado do estator era feita utilizando-se betume ou cunhas de fixação, ou ainda inserindo-se um par de peças semicondutoras de borracha de silicone entre a barra e as paredes da ranhura correspondente. Conforme a técnica anterior mais próxima desta invenção, as ditas barras são fixadas através de duas molas onduladas que formam um assento elástico, estando a primeira mola localizada abaixo da cunha ou estaca de fechamento da ranhura, e a segunda mola entre a barra e a parede lateral da ranhura. Este sistema é inconveniente pelo fato de a segunda mola ondulada ter de ser adaptada e introduzida manualmente após a colocação da barra. Ademais, tal mola ondulada dificulta acentuadamente a condução térmica da barra para o núcleo laminado. De acordo com os ensinamentos específicos desta invenção, uma camada permanentemente elástica (7) é aplicada a uma das faces laterais da barra (3) antes de sua introdução na ranhura (1). Sendo a largura da ranhura ligeiramente menor que a largura total da barra (3), incluindo a largura da camada elástica (7), esta comprimirá com força relevante a barra (3) contra uma das paredes laterais da ranhura (1), fixando a barra (3) com segurança durante a vida útil da máquina elétrica. Ainda de acordo com a presente invenção é previsto um processo de automatização da aplicação de camada permanentemente elástica (7).Invention Patent: <B> "ELECTRICAL MACHINE, LAMINATED CORE AND ELECTRICAL MACHINE ASSEMBLY PROCESS '' <D>. The present invention relates to an electric machine having a stator with grooves in which are unprecedentedly fixed The winding elements generally comprise a laminated core, which is also called a sheet pack, Said windings are, as a rule, realized as bars electrically connected to each other, which can also be connected to the output connections of the respective For the present invention, said bars go through a resin application process and are usually called polymerized bars.The fixation of said polymerized bars in the respective grooves of the laminated core of the stator was done using bitumen or fixation wedges, or by inserting a pair of semiconductor silicone rubber parts between the bar and the walls of the correct groove According to the prior art closest to this invention, said bars are fixed by means of two corrugated springs that form an elastic seat, the first spring being located below the groove wedge or peg, and the second spring between the bar and the side wall of the groove. This system is inconvenient in that the second wave spring has to be adapted and inserted manually after placing the bar. Furthermore, such a corrugated spring makes the thermal conduction of the bar to the laminated core considerably more difficult. According to the specific teachings of this invention, a permanently elastic layer (7) is applied to one of the side faces of the bar (3) before its introduction into the groove (1). Since the width of the groove is slightly less than the total width of the bar (3), including the width of the elastic layer (7), it will compress the bar (3) with relevant strength against one of the side walls of the groove (1), fixing the bar (3) safely during the life of the electric machine. Still according to the present invention, a process for automating the application of a permanently elastic layer (7) is provided.
