APPARATUS AND METHOD FOR MANUFACTURING A MONOLITHIC PERMANENT MAGNET WITH A FOCUSED AND A PARALLEL MAGNETIC FLUX REGION

It is described an apparatus (100) for manufacturing a permanent magnet (150), the apparatus (100) comprising:
i) a first electromagnetic device (110) that is configured to provide a first magnetic flux pattern,
ii) a second electromagnetic device (120) that is configured to provide a second magnetic flux pattern being different from the first magnetic flux pattern, and
iii) a mold (130) that is arranged between the first electromagnetic device (110) and the second electromagnetic device (120), wherein the mold (130) has a mold cavity (131) for receiving a magnetic powder (135).

The first electromagnetic device (110) and the second electromagnetic device (120) are configured so that, when the magnetic powder (135) is placed into the mold cavity (130),
a) a first region (135a) of the magnetic powder (135) is aligned as a focused magnetic flux region (151) having a first angular distribution of magnetization directions resulting in a focused alignment, and
b) a second region (135b) of the magnetic powder (135) is aligned as a parallel magnetic flux region (152) having a second angular distribution of magnetization directions resulting in a parallel alignment.
