Abstract

Es wird eine dynamoelektrische Maschine bereitgestellt, eine hohe Effizienz aufweist und durch ein einfaches Verfahren hergestellt werden kann. Die dynamoelektrische Maschine umfasst einen Permanentmagneten (45), der mehrere Magnetpole auf einer äußeren Peripherie desselben in Umfangsrichtung anordnet, ein Spulenbefestigungselement (41), das einen zylindrischen Walzenteil (42) an einer Position hat, an der der zylindrische Walzenteil (42) dem Permanentmagneten (45) mit einem Luftspalt gegenüberliegt, der dazwischen gebildet ist; eine Zylinderspule (44), deren gesamte Fläche an einer äußeren Peripheriefläche des zylindrischen Walzenteils (42) des Spulenbefestigungselementes (41) befestigt ist, ein Joch (43), das aus einem magnetischen Material hergestellt ist, welches an einer Position angeordnet ist, wo das Joch (43) einem äußeren Peripherieabschnitt der Zylinderspule (44) gegenüberliegt, und ein äußeres Element (50), wobei das Joch (43) auf einer inneren Peripherieseite des äußeren Elementes (50) angeordnet ist.A dynamoelectric machine is provided which has high efficiency and can be manufactured by a simple process. The dynamoelectric machine includes a permanent magnet (45) circumferentially arranging a plurality of magnetic poles on an outer periphery thereof, a coil fixing member (41) having a cylindrical roller member (42) at a position where the cylindrical roller member (42) is the permanent magnet (45) is opposed to an air gap formed therebetween; a cylindrical coil (44) whose entire surface is fixed to an outer peripheral surface of the cylindrical roller part (42) of the coil fixing member (41), a yoke (43) made of a magnetic material disposed at a position where Yoke (43) is opposed to an outer peripheral portion of the cylindrical coil (44), and an outer member (50), wherein the yoke (43) is disposed on an inner peripheral side of the outer member (50).
