O QUE SIGNIFICA SYNCHRONOUS MACHINE EM INGLÊS
Motor síncrono
Um motor elétrico síncrono é um motor CA no qual, no estado estacionário, a rotação do eixo é sincronizada com a freqüência da corrente de alimentação; o período de rotação é exatamente igual a um número integral de ciclos de AC. Os motores síncronos contêm eletroímãs no estator do motor que criam um campo magnético que gira no tempo com as oscilações da corrente da linha. O rotor gira no passo com este campo, na mesma taxa. O motor síncrono e o motor de indução são os tipos de motor CA mais amplamente utilizados. A diferença entre os dois tipos é que o motor síncrono gira em sincronismo exato com a freqüência da linha. Em contraste, o motor de indução requer "deslizamento", o rotor deve girar ligeiramente mais lento do que as alternâncias de corrente alternada, para desenvolver torque. Portanto, pequenos motores síncronos são usados em aplicações de temporização, como em relógios síncronos, temporizadores em aparelhos, gravadores de fita e mecanismos de precisão em que o motor deve operar a uma velocidade precisa. Motores síncronos estão disponíveis em tamanhos sub-fracionados auto-excitados para tamanhos industriais de alta potência.
definição de synchronous machine no dicionário inglês
A definição de máquina síncrona no dicionário é uma máquina elétrica, cuja velocidade de rotação é proporcional à freqüência do suprimento de corrente alternada e independente da carga.
