I am trying to interface with a stepper motor, but I am having trouble with this particular stepper motor, it has 8 wires, from what I've read, it can be wired as a unipolar or bipolar (series, parallel).
The motor is a Tamagawa TS3166N913. In the nameplate it says 4.3 ohm/0.9 deg/step 400s/r
Their website no longer has the datasheet for this particular motor.
I was already able to identify which wires are paired:
gray and purple - 2.2 ohms
white and red - 5.2 ohms
blue and yellow - 5.2 ohms
orange and black - 2.2 ohms
I tried wiring it as a bipolar parallel by connecting the following wires:
gray with white = A
red with purple = A'
black with blue = B
yellow with orange = B'
But when I connected it with my driver board, the motor would just jerk around.
