ABSTRACT:
A motor control device includes first and second pairs of transistors each connected to a power source, the first pair of transistors being adapted for connection to the terminals of the motor and capable of operating to connect the motor to the power source so that the motor is driven in a forward direction when the first pair of transistors conduct, the second pair of transistors being adapted for connection to the terminals of the motor and capable of operating to reversibly connect the motor to the power source so that the motor is driven in a reverse direction when the second pair of transistors conduct, first and second input terminals capable of receiving as input a signal for controlling the motor, a first element connected to the first input terminal and responsive to said signal to cause the first pair of transistors to conduct, the first element including a device responsive to said signal to prevent conduction of the second pair of transistors, a second element connected to the second input terminal and responsive to said signal to cause the second pair of transistors to conduct, the second element including a device responsive to said signal to prevent conduction of the second pair of transistors, and apparatus for supplying said signal to at least one of the first and second input terminals.
