Abstract

"MáQUINA ROTATIVA ELéTRICA CONECTADA EM MALHA COM VãO MUTáVEL". A presente invenção refere-se a um aparelho rotativo elétrico, que tem impedância variável. Isso é obtido pela conexão de um dos componentes polifásicos do aparelho em uma conexão em malha. O valor de vão, L, de uma conexão em malha como essa pode ser variado pela mudança do conteúdo harmónico suprido por um componente de inversor. Também é provido um método para a conexão de um inversor a um motor, onde um arranjo de comutação permite a alteração simples entre várias conexões em malha de diferentes valores de vão, mudando-se, desse modo, a relação de Volts / Hertz do motor."ELECTRIC ROTATING MACHINE CONNECTED WITH MUTTABLE SPANK". The present invention relates to an electric rotary apparatus having variable impedance. This is achieved by connecting one of the device's polyphase components to a mesh connection. The span value, L, of such a mesh connection can be varied by changing the harmonic content supplied by an inverter component. A method is also provided for connecting an inverter to a motor, where a switching arrangement allows simple switching between various mesh connections of different span values, thereby changing the motor's Volts / Hertz ratio. .
