I want to drive 5 pole stepper motor
specs 500 steps /rev
2A 0.34ohm per winding
there is only five terminals and between any two terminals resistance is about 0.6 ohms
I this is not like unipolar or bipolar motors
Can some one help me how to drive this ( basic driver circuits)

If it's 5 terminals it's a unipolar stepper, you're measuring the resistance wrong somehow. There should be 1 common wire, and the other 4 wires are the output at the end of each of your four coils. The simplest way to drive them is to provide the common wire with +VCC and use mosfets as lowside drivers to ground the coils in the proper sequence.

Even with a 5 pole motor you would get different resistance values between any two points.

Ehh, I see now. I apologize, I never ran across one of them before.

Might help.

The end of the page shows some information on non standard multi phase steppers and shows stepping sequences for a 5 phase motor.
