Good morning everyone,
I've been studying stepper motor functioning in order to choose the right one for my application with proper control board.
Before buying I wanted to ask your opinion just to make sure I'm buying the right things.
I need a motor capable of exerting a 20 Nm torque when spinning at 10 RPM or lower.
I've choosen the follow

I am at the moment trying to make a stepper motor move, but can't seem to make it happen.
I am interfacing it through a control board, which takes the input Step, Dir, En, and 5V.
I am providing those inputs signal from an arduino, but can't get the damn thing to move. all it does it move a step forward and backwards, like it

Microprocessor PWM units are not well suited to drive stepper motors. Instead use timer interrupts and pulse pattern generation in software.

That's the usual way to operate stepper motor with constant current. Unipolar motors like yours are more often operated with constant voltage, yours is obviously designed for a lower voltage than 12V.
In any case you should get an i

L6474 is designed to perform individual steps triggered by a digital input. All operation parameters are set through SPI.
If you need only slow stepper motor operation, you can perform steps by writing to the electrical position register without using GPIO pins.

This is a brochure not a datasheet, there are no electric specs in it for the stepper motor.
And it describes more than one expansion valve type. The lessest you should do is to tell the exact type number of your valve.

I can't see how you want a stepper motor to move.
You just control two outputs: pc0 and pc3.
If one channel is higher, them pc0 is ON and pc3 is OFF.
When the other is higher, the, pc0 is OFF and pc3 is ON.
If both are the same, then it repeats the previous state.

Wait. YOU are asking US if you miswired your circuit? And how, exactly, would you expect us to determine that?
But forgetting that for a moment, you need to control the average current to your motor windings. I think you need to learn something about driving stepper motors, PWM, feedback and such.

Your stepper motor is working exactly as it's supposed, it moves in steps! If you want it to run faster, you'll have to give it a faster step rate. I'm not sure why you are comparing a step motor to a speedometer, though; they are two entirely different things.
What are you using to control the stepper?

As chuckey said, stepper motors are best used with current source drivers. It doesn't need to be complex, you just need a peak current mode control loop on each half bridge.

It is quite common/useful to use PWM for speed control whether you are using a stepper motor or simple brushed DC motor with feedback or measuring motor emf. With many robot arm applications it is important to have the position or angle so most often a stepper (in which you know how many degrees per step) or a motor with encoder or (...)

In a bipolar stepper driver, you can measure the current with low-side shunts. You may have noticed that stepper drivers are often operated in constant current mode. In this case, measuring shunts and a current control loop will be already present in the driver circuit.
