MOTOR CONTROL APPARATUS FOR REEL-TO-REEL TAPE DRIVE SYSTEM ABSTRACT OF THE DISCLOSURE A motor control apparatus including a first motor (16) driving a first reel (2) a second motor (26) driving a second reel (1), independently operable to the first motor, and a unit (5) for tensioning a tape being transported between the first and second reels, having a member (51) engaging the tape and an arm (52) jointed to the member, movably fixed and energized by a prede- termined force (54) so that the tape energizing the member is tensioned at a predetermined force. The motor control apparatus further includes a unit for detecting a displacement (?) of the arm, a transport speed (N) of the tape, a diameter (DA) of the tape wound on the first reel, and a tension (T) in response to the displacement and diameter, and a unit for controlling the first motor in response to the tension and the second motor in response to the transport speed.
