STEPPING MOTOR ENERGIZING CIRCUIT AND METHOD FOR MINIMIZING STEP POSITION ERROR

摘要

STEPPING MOTOR ENERGIZING CIRCUIT AND METHOD FOR MINIMIZING STEP POSITION ERROR The ability of a stepping motor to assume the same static rotational position for each step when a step position results from simultaneous energization of two windings is enhanced by having the same quantity of current flow through both windings by always connecting in series the windings that are energized with the source of unidirectional power.
