This is a general question for any motors like that. There are some others that i would like to do the same thing with but i dont know the numbers of those.
It seems like they were designed to move in a random direction. I just want to know what causes the randomness so maby i can make it predictable.
Not sure about these motors but the other ones i have will change direction if you stop them with your hand.
I think i might end up with a simple on/off circuit instead of directional control

Hi,
What is the number of leads coming out of the motor?
Best regards,

Hi,
If your AC synchronous motor has only two leads (one winding), then
you cannot control the initial direction unless the motor uses a
mechanical device (anti-return) which is placed on the rotor.
Reversible AC Synchronous Motors have 4 leads or more. (Two windings or more).

As you have probably figured out by now the "B" stands for Bidirectional.
Motors like this are designed to change directions under a certain load or if stopped. (light bar in scanner?)
Like Alain said, contact the manufacturer to find out how they did it in this motor but it is most likely like Luciano shows with the CW/CCW built in on an actuator. Now if you feel lucky take one apart and see if they can be bugged into.

I see. I was hoping there would be a controllable reason why they go a random direction on startup. I will just make a simple on/off circuit for them then.
mackrackit, they are in abstract twister 3's
Thanx everyone for your help
