Step motor issue - Mini 4 Phase 5 Wire Stepper Motor

[Renaudp]

I recently purchased the following step motor https://www.aliexpress.com/item/1005002015409007.html.
I don't find any spec nor example about how to properly use it with arduino.
It's connected to an ULN2003.
I've tryed the following pulse sequence, with a delay of 10microsec between each pulse.
1010
1001
0101
0110

and
1000
0100
0010
0001

and
1000
1100
0100
0110
0010
0011
0001
1001

The shaft moves a little bit then come backward.

Any help is welcome.

It sounds like you do not have the phases in order. Does this help:

Really? 100 000 steps per second.

Try 10 milliseconds.

Oops was 10ms!
I've tryed different delays without success.

Perhaps this can help.

Does the motor have any numbers and lettering on it?

I've tested this model. It's working. I need a small stepmotor without gearbox.

MMmm. the wiring was not correct ... Thank you all!

It's connected to an ULN2003.

How?
