BI-DIRECTIONAL ENERGIZING CIRCUIT FOR A STEPPING MOTOR

A stepping motor having its stator windings connected into two phases is advanced one step by reversing the direction of current flow in one of the phases. Each phase is connected to a D.C. source by a pair of paths with each path directing current in a different direction through the phase. The pat...

Zusammenfassung:	A stepping motor having its stator windings connected into two phases is advanced one step by reversing the direction of current flow in one of the phases. Each phase is connected to a D.C. source by a pair of paths with each path directing current in a different direction through the phase. The paths are alternately shiftable from conducting to non-conducting with the shift of a path to being conducting being delayed until current flow from the path shifted to non-conducting is essentially zero to prevent short circuiting between the paths.
