  • Bidirectional motor drive using switched amplitude controlled current
    Patent number: 3978384
    Abstract: In the computer field tape handlers for magnetic tape are widely used. The magnetic tape is moved by a capstan driven by a high power low inertia motor since it is necessary to rapidly accelerate and decelerate the tape in both forward and reverse directions. A high power motor is provided with a command controlled direct current. The motor direction is determined by the selection of one of two pairs of solid state switches. Only one current control circuit is used. Transients are minimized by permitting only one pair of switches to be closed at any time and by switching when the controlled current is at a low value.
