An apparatus (10) for producing magnetic material from a slurry (13) containing magnetic particles and a fluid comprises a mold containing the slurry (13), a press (12), and a magnetic field generator (16). The press (12) presses the slurry (13) along a pressing line (PL), and the magnetic-field generator (16) produces a magnetic field that passes through the slurry (13) substantially perpendicular to the pressing line (PL) to orient the magnetic particles in the direction of the magnetic field. The magnetic-field generator (16) can be an electromagnet that includes two opposing poles (26, 28) that bound the mold. The press (12) can include a pair of opposing rams with the rams applying pressure to the slurry (13) and being aligned along the pressing line (PL). A method for using the apparatus to produce magnetic material and a method to use the material to produce a high speed controlled-pole rotor are also disclosed. |
