Checking a Stepper without a Driver

[baberjaved]

Is there any possible way of just checking out if a stepper motor works or not without using a driver/controller? I dun want the motor to rotate.. it could just budge a little to indicate that its working fine...

A battery (I use a PJ996 6V one), and two wires - you can also work out which wire is which.

yeah Thanks... it budged! =D

yeah Thanks... it budged! =D

Now go round the rest of them, and find out what sequence you need to make it rotate.

I just finished making the L298/L297 Circuit for a Bipolar 2-Phase stepper motor... But before hooking it up with my microcontroller circuit i want to check n make sure the circuit is working fine... How do i check it and what should be the voltages on the output of the L298 and what should be the voltages on the Clock,Enable,CW/CCW and Reset pins of the L297...

I connected the chips to 5V and the Vdd of L298 to 30V and I am getting around 6V on the above mentioned pins of the L297 (It would be safe to connect it to a uC?) and on two outputs of L298 I am getting 0V and 17V on the other two...
Why 17V? Should it be this way...?
Secondly i wanted to know which wires of the stepper motor would go into the four outputs? Does the order matter... as when i change the configuration the voltages on the output change....

Here's the circuit.. Is something wrong or missing?
What should be the output on the four outputs of the L298?

hey, please go through these links and directly apply 6V battery to the motor to check whether its working or not......

Also, u may find out which wire is which, please check out the link below:
