ABSTRACT:
A stepping motor (31) drives a load (33) such as an ink ribbon in a printer which exerts reverse torque on the motor shaft (32) thus displacing the shaft (32) slightly in the reverse direction when a low hold current is applied to a motor phase. Prior to switching the motor (31) to a next phase for rotation, a high drive current is applied to the present phase. After a certain length of time which is sufficient for the shaft (32) to be moved to the correct present position, the phases are sequentially switched while the high drive current is applied for rotating the shaft (32) and load to a new position.
