Abstract (en)
[origin: WO2022018344A1] A method for manufacturing magnetic circuit loops for a multi-phase transformer from a magnetic strip, the method comprising the steps of: a) providing a magnetic strip of constant width in the form of a roll wound around a first circular mandrel and extending along a longitudinal axis; b) producing a first and a second half-roll by cutting the roll into sections, the two half-rolls having a longitudinal axis each comprising a respective boundary surface which is formed once it is separated from the other half-roll, the roll being cut slantwise at an angle θ relative to the longitudinal axis, such that the first half-roll constitutes a first loop having its boundary surface outwardly oriented relative to its longitudinal axis, while the boundary surface of the second half-roll is oriented opposite to the boundary surface of the first half-roll; c) aligning the first and second half-rolls to form two loops, including at least one sub-step of reversely unwinding and rewinding the second half-roll on a mandrel.
