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 carrier roll winding machine for winding up a web, such as a paper web. Two carrier rolls form a winding bed for a reel and the reel is fed with a web wrapped around the bottom of and then passing between the two rolls and to the reel. A blow box beneath the space between the carrier rolls having a compressed air con...
A core onto which a web is to be wound is adapted to be moved into peripheral engagement with one side of a web support such as a winding drum or roll over which the web passes. A cutting strip of polymethylene terephthalate is positioned between spaced portions of the web and roll, and has a central portion in registe...
Apparatus for winding and unwinding a cable of which one end makes electric contact with a fixed installation. The cable (6) has one end which makes electric contact with a fixed installation (18). It is wound on the peripheral portion of a fixed plate (15). A duct (17) fastened to a shaft (24) mounted for rotation rel...
Disclosed herein is a method of manufacturing a continuous disk winding for high-voltage superconducting transformers that has special features of no joint and low loss, which are advantages of a layer winding, while being formed in the shape of a disk winding, which is advantageous in voltage distribution and insulati...
The invention provides an apparatus for winding material. The apparatus includes first and second roll carriages that are each configured to support a roll shaft. At least one of the first and second roll carriages is configured to be rotated by a drive member. The apparatus also includes an engagement roller displacea...
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...
An electric motor drive system includes an electric motor including windings for separate phases including a center tap, a winding for a low-speed rotation located between the center tap and a winding start terminal, and a winding for a high-speed rotation located between the center tap and a winding end terminal; an i...
A device for supplying energy to a long stator winding having multiple winding sections. The device includes an energy source, a supply line connected to the energy source, section switches that are connected to the supply line and that each have a connection for connecting the switch to one winding section each. The d...

The disclosed stator or rotor has a distributed wave winding, in which the wires are associated in pairs lying with straight segments in the same slots. Head portions of two successive straight segments of each wire of a pair protrude from opposite ends of slots. For forming two wire groups, a plurality of coil winding...
L'invention concerne un procédé de collage d'un film adhésif dans lequel l'adhésif ne dépasse pas lorsque l'on tire et colle un long film adhésif enroulé sur une bobine, et empêchant tout démariage et sortie de noyau. Dans le procédé d'extraction d'un film adhésif (2) enroulé sur un...
An unwinding assisting device for an automatic winder. The automatic winder has a winding position at which a cop of yarn is unwound from a take-up tube supported on a tray. A lifting mechanism raises the tray at the winding position as the cop of yarn is unwound from the take-up tube. A tubular member receives the tak...
A stator winding includes a plurality of winding sub-portions in each of which a strand of wire formed from a continuous wire is wound so as to alternately occupy an inner layer and an outer layer in a slot depth direction within slots at intervals of a predetermined number of slots and form a lap winding having two tu...
A method of securing a stator winding such that it has improved heat dissipation performance includes steps of inserting a stator winding into a stator core soaking these components in a varnish tank while being held together as one, and after the varnish has soaked into the stator winding 15 , withdrawing the winding...
One end of a winding band is secured to a winding core. The winding band travels from a supply spool over a deflection roll rotating at a circumferential velocity corresponding to the conveying velocity of the product conveyor delivering the printed products. The winding core is driven during winding up of a product pa...
