The present invention relates to rotor windings directly cooled by a liquid and used in implicit-polar synchronous machines. The rotor windings comprise two groups of coils wound in different directions, disposed in one and the same slots. All the electric and hydraulic connections of the leadouts of the coils are disp...
A pole piece is secured to a magnet by means of a connecting element running perpendicular to the common plane of the confronting surfaces of the magnet and the pole piece. The connecting element is welded to the pole piece and/or the magnet by electron bombardment or by means of a laser so as to cause minimum disturba...
Methods and structures for the fabrication of a thin film, perpendicular recording write head are disclosed. The fabrication involves the deposition of two different oxide layers which have mutually high etch selectivities. This characteristic allows a write pole structure to be built wherein the track width is indepen...
A method and apparatus for winding multi-pole stators formed by a sheets stack ferromagnetic core, having a plurality of radially extending poles defining grooves between them. Said wireis wound about said pole extensions, spooled by a flier, and guided by shrouds, which move radially with respect to said stator overla...
