48 stepper motor

I am trying to figure out why a stepper motor with a stepper rating of 48 but only has a true step ratting of 32.

I am trying to figure out why a stepper motor with a stepper rating of 48 but only has a true step ratting of 32.

Those numbers appear to be part of the motor "part number", not the number of steps per rotation.

" explain why the servo you have has a rating of 48 steps but the true steps are only 32."

I am trying to answer this.

I don't see why.... It seems like the datasheet says 48 steps too. I could just be over thinking it..
Maybe because it is defined in the code as a 32 step?

The other thing I am thinking is that the motor was just miss labeled and sold this way by china.

Maybe because it is defined in the code as a 32 step?

That dosn't change the physical movement of the motor, it just defines what the software "thinks" is one rotation.

Most of these motors(*) have non-integral gear ratios and are not an integer number of steps per revolution, note. They are made for moving car air-conditioning/heater air-flow vanes, I believe, so exact gear ratios
are of no consequence to the manufacturers. The gears are not designed for anything but light duty.

(*) I believe people have identified at least two versions.

There's another thread about them from a while ago: http://forum.arduino.cc/index.php?topic=71964.0
