hi
i am tring to drive a stepper motor STH-39D. i am getting the control signals from a FPGA Controller. the voltage levels of high and low signals of my control output are 4.4v and 1.37volts. i am using the following circuit as driver. i am using BC547 trasnsistors. the motor is not rotating. what might be the possible cause.
i think this is because of that the transistor is remaining ON even on "0" position. what changes in circuit should i make for this motor to keep running.
by the way forgot, my stepper motor is 1.8 step angle, 13ohm, resistance, 6 wired motor.
