CYLINDRICAL COIL AND CYLINDRICAL MICRO-MOTOR USING THE SAME

摘要

[PROBLEMS] To form a highly accurate and fine-structure coil pattern and to provide highly accurate cylindrical coil having an excellent mechanical accuracy such as circularity and deviation and a cylindrical micro motor using the cylindrical coil. [MEANS FOR SOLVING PROBLEMS] The cylindrical coil is formed with a cylindrical base surface on which insulation layers having a through hole and coil pattern layers formed by conductive nano particle paste are alternately printed by an ink jet nozzle array. The coil patterns overlaid are electrically connected to one another by the conductive nano particle paste filled in the through holes. The outermost layer is formed by the insulation layer having no through hole.
