Abstract
Patente de Invenção: <B>"MOTOR ELéTRICO, EM PARTICULAR, MOTOR DE RELUTâNCIA"<D>. Um motor elétrico já conhecido, que pode ser acionado como motor de relutância possui, em uma execução de baixo custo, um estator com um corpo de conclusão em forma de anel, e partindo desse corpo radialmente para dentro, seis dentes de pólos de corrente do estator e nesse dente de pólos de corrente do estator está apoiado, podendo girar, um rotor com quatro dentes de pólos de correntes do rotor. Bobinas de excitação que estão coordenadas aos seis dentes de pólos de corrente do estator estão ligadas de tal forma que, o motor elétrico pode ser acionado em três fases. é desvantajoso que, dentes de pólos de corrente do estator que ficam diagonalmente opostos um ao outro, então, quando suas bobinas de excitação são alimentadas com corrente, movimentam o corpo de conclusão elasticamente contra o rotor e, nesse caso, se deformam elipticamente. Deformações elípticas desse tipo levam a propagações de ruído. De acordo com a invenção é sugerido que o número de dentes de pólos de corrente do estator (201, 202) e de dentes de pólos de correntes do rotor (301) sejam selecionados de tal forma que, no caso de uma relutância mínima, em conseq³ência de um alinhamento de rotação do rotor (300) em relação ao estator (200), entre três pares de dentes de pólos de corrente do estator (201, 202) e dentes de pólos de correntes do rotor (301), sejam formadas três fendas de saída do ar que podem ser atravessadas. Isso tem como conseq³ência que, em relação ao estado da técnica, de agora em diante, três zonas de corpo de conclusão (210) são puxadas elasticamente em relação ao eixo de rotação do rotor (310), e em conseq³ência disso, as zonas do corpo de conclusão (210) deformadas elasticamente, só abrangem, em essência, 120°, e em conseq³ência disso, atuam de forma mais rígida. Disso resulta a vantagem que, no caso da freq³ência de excitação igual, as deformações são realizadas com amplitudes mínimas e, com isso, com menos desenvolvimento de ruído.
