Printed circuit board for textile machine used for processing or handling of fiber material, has spiral-shaped conductors that are connected with upstream diode arrangement for dissipation of electrostatic discharge

摘要

The printed circuit board (1) has outputs (6-9) that are provided for energizing the windings (27,28) of stepping motor (10). The spiral-shaped conductors are formed helically to the outputs of circuit board. The spiral-shaped conductors are connected with upstream diode arrangement (23-26) for dissipation of the electrostatic discharge. The diode arrangement is formed so that electrostatic discharge in the direction of the inputs of the circuit board is derived for the power supply. An independent claim is included for textile machine.
