PURPOSE:To eliminate unstable starting conditions due to backlash in rotation when stepping rotation is stopped due to four-phase excitation with respect to the control method for stepping motor for slot machine type pinball machine. CONSTITUTION:In the control method for a stepping motor for a slop machine type pinball machine in which the stepping rotation is stopped by four-phase excitation, the next starting phase (Y) is driven from a motor phase (B-C) advanced in the direction of stepping rotation based on a stop phase (X) as a reference during four-phase excitation according to its configuration. |
