Embodiment Construction
[0019] Such as image 3 shown. A magnetic field orientation device for anisotropically bonded or sintered multi-pole ring magnets, including an excitation coil 4, two magnetic poles 5, 6 and a cylindrical mold core 7 made of magnetically permeable materials, and the opposite polarity of the two magnetic poles Each head has a semi-cylindrical surface concentric with the mold core. The two magnetic pole heads are closed to form a circular cavity. A cylindrical core 7 is placed in the center of the circular cavity. The outer surface of the core is in line with the circular shape. The inner surface of the cavity forms an annular cavity 8 . In order to reduce the magnetic short circuit, the width of the contact surface 11 of the pole heads of the two magnetic poles is smaller than the thickness of the annular cavity. The two magnetic poles are fixed with a magnetic spacer 9 across the pole heads of the two magnetic poles, so that the two pole heads and the two magnetic spacer blo...
