ABSTRACT:
An electric transformer includes a magnetic circuit and, for each phase, an electrical winding including at least one coil, wherein each electrical winding is made of a good conductive material wire or band, notably aluminum, wound about a wheel rim-shaped annular former. Each magnetic circuit is made of at least one elementary circuit, provided by coiling a magnetic metal strip of constant width, and is formed with a window for the passage of the corresponding winding or windings, has the shape of an irregular polygon with an axis of symmetry. The magnetic circuits are positioned and maintained on a support plate allowing the passage of the windings.
