CA 2490089

This invention relates to an alternating current electric motor, single phase or multiphase or synchronous generator, with primary windings (main windings) and de-saturation additional windings. Each additional winding is fed through one or more multiple capacitors in opposite phase angle and opposite field directions from each respective main windings. The total cross sections of the wire used on each main and additional winding are of predetermined sizes and preferably follows the approximate ratio of approximately 2/3 for the main winding and approximately 1/3 for the additional winding, and this capacitor value is of a predetermined size. The method of construction is characterized by the two windings being built at one time in a single operation as a single step.

L'invention se rapporte à un moteur électrique à courant alternatif générateur synchrone ou monophase ou multiphase, pourvu d'enroulements primaires (enroulements principaux) et d'enroulements supplémentaires de désaturation. Chaque enroulement supplémentaire est alimenté par l'intermédiaire d'un ou de plusieurs condensateurs en opposition d'angle de phase et dans des directions de champ opposées à partir de chacun des enroulements principaux respectifs. Les sections transversales totales du fil utilisé sur chaque enroulement principal et supplémentaire sont de tailles préétablies et de préférence suivent le rapport approximatif de 2/3 environ pour l'enroulement principal et de 1/3 environ pour l'enroulement supplémentaire et cette valeur du condensateur est préétablie. Le procédé de fabrication se caractérise en ce que les deux enroulements sont construits en même temps, en une seule opération et au cours d'une étape unique.
