Hello
Does any one know the fastest stepper motor (highest rpm) that can interface with Arduino?
Can I use a stepper motor driver on fastest stepper motor (highest rpm) to interface it with the Arduino?
Is there a specific stepper motor driver for the fastest stepper motor, or will any driver work?
Thanks

No, no one knows the fastest, like the gun slingers of the Wild West their is always a faster one round the corner.
Can I use a stepper motor driver on fastest stepper motor (highest rpm) to interface it with the Arduino?
In what way is this a different question?
Now do you want to ask a sensible question?
How fast do you want the motor to run?
What resolution do you need on the stepping angle?
What is the required torque for the motor?
How fast do you need to accelerate up to the fastest speed?

It depends on how you generate step pulses - for instance AccelStepper has a modest maximum
step rate, and it depends on your microstepping ratio. For instance a top-rated CNC stepper
and driver would need perhaps 200,000 steps/second. Such motors are very low resistance and
low inductance (~ 0.5 ohm, ~ 1mH).
If you move away from standard 200 steps/rev steppers to non-standard with less steps/revolution
you automatically increase the top speed (but lower angle resolution).

You always have to use a stepper driver on a stepper motor to interface it.

Steppers go faster with higher voltage supply into a chopper driver, drivers each have a maximum
voltage rating.
What are you wanting to do? Is a stepper the right approach?

I am trying to build a toy helicopter. Hence I was hopping to use a fast stepper motor to rotate the wings clock wise. The reason I want a stepper motor is you can control there speed. I need speed control to steer the helicopter. If any one knows a better way to approach this then please let me know.
Thank you

Are you expecting it to fly? A stepping motor is way too heavy to lift itself. You want to use the brushless DC motors they use in quad copters.
Brushless or slotless motor is mandatory for

Steppers are the heaviest and least energy efficient motor you can get, completely unsuitable by at least an
order of magnitide.
For small helicopter coreless slotless motors are used, which are extremely high speed miniature brushed
DC motors, and for larger loads RC brushless motors are used. Only these have the power to weight
ratio you require.
