Method for assembling a magnetic pole element for a rotor for an axial flow electric machine

Method for assembling a magnetic pole element for a rotor for an axial flow electric machine, said rotor comprising a body in the form of a disk centred on an axis of rotation and extending in a main plane, said body having at least one housing, said magnetic pole element comprising a plurality of single magnets, said method comprising the following steps:

• e1) forming a first row of at least two single magnets and retaining single magnets of said first row using a strip of adhesive material;
• e2) placing said first row on an assembly support having a curvature that is equal or substantially equal to the curvature of a peripheral edge of the housing about the axis of rotation such that the single magnets of said first row are placed along a first line which is comprised in an assembly plane and has a non-zero curvature;
• e3) forming another row of at least two other single magnets and retaining single magnets of said other row using another strip of adhesive material;
• e4) placing said other row on said first row, such that the single magnets of said other row are placed along another line which is comprised in said assembly plane and has a non-zero curvature;
• e5) repeating steps e3) and e4) until the magnetic pole element is assembled.
