m35sp-9t

hai all,
can any one tell me about Mitsumi M35sp-9T stepper motor i got from scrap, it has five terminals but i cant determine it is a unipolar or bipolar.
i checked with multimeter but it behaves like a bipolar . i made it to run using a H-bridge by single stepping for a bipolar motro, it worked but not double stepping. can any one give its internal circuit or say its unipolar or bipolar.


regards,
murugan

Based on the Matsushita Stepper Motor (55SPM25D6NL):

5 wire is UNIPOLAR

Red = phase 1(A+)
Yellow = phase 2 (B+)
Brown = phase 3 (A-)
Blue = phase 4 (B-)
White/Black = common

Bipolars can have 4, 6 (for universal bipolar/unipolar usage) or 8 wires.
