PRINT HAMMER COIL WITH A DEVICE FOR SCREENING THE MAGNETIC FIELD AND FOR CARRYING OFF THE HEAT |
摘要 |
A heat exchange system for an electromagnetically operated print hammer of a print hammer bank provides internal and external heat transfer for the operating windings. A non-magnetic metal bobbin of the heat exchange system provides conductive transfer of heat from the interior of the operating winding to the magnetic core. Flat parallel plates of magnetic material are attached to the sides of the operating winding for external heat transfer and magnetic flux shielding. The plates may have multiple laminations having different saturation and permeability characteristics. |
