Adding magnetic powder to the polymer, i.e., making a polymer magnet, does not require additional fabrication steps. Adding magnetic powders is compatible with the molding process described herein. According to an embodiment, another method for producing scanners uses widely available epoxy-glass ...
The raw material used in experiments was the primary silicon powder prepared from the kerf loss slurry waste by centrifugation at Henan Solar Energy Silicon Products Company, China. The primary silicon powder was ash black with slightly metallic luster, consisting of Si and metal fragments (mainly ...
The stator pole pieces form part of a means for providing a rotating magnetic field in the region of the rotor. The rotating magnetic field can be provided, for example, by a rotating magnet beneath the substrate on which the rotor is mounted, or by an external magnet which couples a magn...
