Help selecting stepper motor

Hi everyone,

I need to use a stepper motor to move a robot arm.

I have a motor that I need to use. It is a 6 wire 200 step motor. The only information I have about it is its voltage is 3V current 4A and that I have to command it at 50Hz.

I would like to know what type of motor it is: hybrid, variable resistance or permanent magnet? How to find out???

thanks in advance

Hi @Arloa and welcome to the forum.

Could you maybe post here some photos of the motor?

Are there any labels with part numbers on it?

Thank you.
