APPLICATION OF A CYLINDRICAL MOVING COIL LINEAR DC MOTOR TO PRINTER HEAD

We have studied a cylindrical moving coil linear DC motor to ink jet s huttle printer that make it possible to print with high speed, high re solution and low power consumption. The actuator is supposed to be dri ven using resonance of spring plates which are placed at the end of th e permanent magnet and the armature respectively. However, the permane nt magnet and armature of the actuator did not resonated at the same f requency and the spring coefficient changed because these were fixed t o the supports by screws. At present, a new support mechanism is being made.
