Abstract

Les problèmes que l’invention se propose de résoudre consistent à former une spire de haute précision et structure fine pour obtenir une bobine cylindrique de haute précision aux excellentes propriétés de précision mécanique telles que circularité et déviation et un micromoteur cylindrique utilisant cette bobine. Les solutions trouvées dans le cadre de l’invention consistent à former la bobine cylindrique avec une surface de base cylindrique sur laquelle des couches d’isolation percées d’un trou et des couches de spires formées par une pâte conductrice de nanoparticules sont imprimées alternativement par une série de buses à jet d’encre. Les couches de spires supérieures sont connectées électriquement l’une à l’autre par la pâte conductrice de nanoparticules qui emplit les trous. La couche extérieure est une couche d’isolation sans trou.
