NMB PM55L-048; how to wire!?!?

Hello to all,

I have buyed a EasyDriver controller and I command it with an arduino 2009.

It work just with a motor NMB PM20S-020 but not with an NMB PM55L-048.

The PM20S wires are: black, red, brown and gray, red, yellow; I have plug on the EasyDriver connector just the black-brown (for A coil) and gray-yellow (for B coil).

It work fine, but wen i plug the MP55L, it make just some noise but it not turn...

The wire colors are black, red, gray and orange, red, yellow.

I have tried to connect black-gray and orange-yellow, and many other combination, but without results...

I have follow this link: http://pminmo.com/phpBB2/viewtopic.php?f=9&t=400

Someone know this motor?

thanks!

You need to use a multimeter on ohms setting to find how the motor is wired, or find the correct datasheet...
