NOVELTY - The method involves optimizing dynamic reconfiguration-switching of motor windings (2904) among winding-configurations for trading off acceleration in favor of higher velocity upon detecting a tape storage drive at optimal angular-velocity for switching to optimal lower torque and voltage constants. Total back EMF (BEMF) is prevented (2906) from inhibiting further acceleration to higher angular-velocity. The reconfiguration-switching is performed among the motor windings by using a wye connection or delta connection system for the drive.    USE - Method for facilitating dynamic reconfiguration-switching of motor windings of a 3-winding-configuration motor, a 4-winding-configuration motor and a 5-winding-configuration motor in a tape storage drive of a tape drive system within a tape transport system by utilizing a processor device i.e. microprocessor. Can also be used for a 1-winding-configuration motor, 2-winding-configuration motor, brushless direct current (DC) motor and electric motor of an electric vehicle or motorcycle and a wind turbine and for a hard disk drive and an optical disk drive or magnetic tape drive.    ADVANTAGE - The method enables selectively reducing the BEMF from a reel motor to increase allowable tape reel angular-velocity for fixed power supply voltage or maintain higher tape reel angular-acceleration such that tape linear velocity or tape linear acceleration can be selectively increased, thus improving performance of the tape transport system.
