Abstract
"DISPOSITIVO DE AQUECIMENTO POR INDUçãO, PARA AQUECER MATERIAL EM TIRA CONTìNUO". Um dispositivo por indução para aquecer material em tira contínuo. Em uma primeira configuração, duas seções de bobina, cada uma possuindo uma espeçamento em uma extremidade para a tira de material passar de lado para dentro e para fora do dispositivo de aquecimento, no qual as seções de bobina estão adaptadas para ligação duas fontes de potência, de modo que a primeira fonte de potência é ligada através de uma meia-espira de cada uma das seções de bobina e, daí, para a segunda fonte de potência, a qual está ligada através das segundas meias-espiras das respsctivas seções de bobina e de volta para a primeira fonte de potência, tudo em série. Em uma segunda configuração, as seções de bobina estão adaptadas para ligação a quatro fontes de potência em série; cada fotne de potência ligada entre uma respectiva meia-espira das seções de bobina, de modo que uma meia-espira é ligada entre cada uma das quatro fontes de potência. A ligação em série assegura amplitude e fase uniformes da corrente elétrica aplicada ao dispositivo de aquecimento por indução.
