Magnetic core for forming part of e.g. rotor of brushless electric motor, has magnetic pole elements that are connected in pairs to annular yoke near end of circumferential part of pole elements by common connection cover
The core has a panel (2) including magnetic pole elements (6) arranged opposite to an annular yoke (4), and a series of orifices (12) for receiving a magnet between the yoke and one of the pole elements. The pole elements are connected in pairs to the yoke near an end of a circumferential part (16) of the pole elements by a common connection cover (10). Each orifice is opened from a side of the end of the circumferential part of the pole elements. Resin is molded on a stack of the panel. An independent claim is also included for a method for fabrication of a magnetic core of a rotating electric machine.
