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.
I've wired it as such and it seems to be doing okay, however the motor doesn't like to be driven fast, might be the limits. It would be great if a datasheet is available, but alas, this motor might just be a rarity.
