    • H01F41/12—Insulating of windings

Definitions

  • the invention relates to a method for isolating shaped coils, in which a strip-shaped machine is used Insulating material wrapped around the bundle of conductors of the form coils becomes.
  • the form coils are only wound by the machine, if the form coils are those specified by the machine Minimum machining sizes in terms of width between the coil sides and / or that formed by the coil legs Have spread angle. These minimum machining sizes are 150-170 mm in terms of spool width and with respect to the spread angle at 90 ° or greater.
  • coil dimensions are often smaller than those of the Vending machines are predetermined minimum sizes. Such a machine is described in document FR-A-2 639 625.
  • the invention has for its object to provide a method with the form coils regardless of those by the installation dimensions specified in an electrical machine by means of a Machines can be wrapped with insulating material.
  • the problem is solved according to the invention in that the form coils in terms of their width and / or their spreading angle formed by the coil legs according to the one given by the machine Processing sizes are enlarged and after application of the insulating material are deformed so that the Installation in an electrical machine required width of the Sets the coil and / or the required spread angle.
  • the form spools can be designed with a spool width and / or a spreading angle, each of which is the minimum machining size of the machine correspond, manufactured and after the insulation process on the for installation in an electrical Machine required dimensions are molded.
  • the expansion and / or reshaping expediently takes place of the coils directly through the one winding the insulation material Machines.
  • the specified procedure creates the possibility Form coils regardless of the size of their coil width or their spreading angle completely by a machine to wrap with an insulating tape.
  • By enlarging of the spreading angle is used for the winding process Organ of the machine also at the point of cranking Front side created enough space so that this organ can carry out the winding of the offset. The same becomes by increasing the coil width Allows winding of the coil sides even with form coils, which are not otherwise wound by a machine could become.
  • the form spools can be used from the start with one for winding sufficiently wide spreading angle due to the machine or sufficient spool width. After this The coils are then wound into the required for installation in an electrical machine final shape and size.
  • the form coils can also be used for installation dimensions required in an electrical machine become. For the automatic winding such Coils then expanded accordingly. Such prefabrication the coils in their final form is special then advantageous if the spreading angle or the coil width the final shape is close to the minimum machining sizes of the machine. The coils can then due to the inherent elasticity be expanded without causing permanent deformation is coming. The coil thus springs after winding practically back to its final form without it a substantial recovery is required.
  • the expansion and / or reshaping can be done by appropriate Devices on the machines winding up the insulating tape respectively. This eliminates the need to move the form coils separate devices with which the appropriate shaping of the Coils would have to be made.
