help nema 17 bipolar 4 wires

Hello guys !

I'm new in this forum and new in arduino.
I decided to buy a nema 17 motor (Nema 17 Stepper Motor Bipolar 2A).

I have an mega 2560 arduino card.
If I correctly understood I need a little card to drive this motor.

I founded 2 cards :

  • L298N
  • A4988

can the motor work with one of these card ?
Do I need anything else to make work these stepper motor ?

thanks for answering (don't forget I'm new dont tell me complicated things thx)

Post a link to the motor specifications.

To use a 2A/winding stepper at its full capability will require you to buy an industrial stepper motor driver and a power supply capable of 3-4 Amperes at 12-48V.

Step motor basics

Hello !

here is the stepper motor !

is a motor like this better ? :
Stepper Motor Specification:
*Step Angle: 1.8 deg.
*Holding Torque: 59Ncm(84 oz.in)
*Rated Current/phase: 1.7A
*Frame Size: 41 x 41mm
*Body Length: 48mm
*Shaft Diameter: 5mm
*Shaft Length: 22mm
*Weight: 380g

Can you link me some example of what I should buy if possible and which card I should take ?!
Thanks

You forgot to tell us what kind of work you want the stepper to perform!!!!

Better for what? Determine the mechanical torque, speed and power required for your project, then choose a motor.

*Rated Current/phase: 1.7A

A DRV8825 stepper motor driver should be just about suitable for that motor and will be considerably cheaper than more powerful drivers that would be needed with a 2 amp motor.

An A4988 would almost certainly be overloaded by a 1.7 amp motor.

the motor will move a tray vertically, there will be a glasse or a fork for example on the tray. I don't really know if the motor is powerful enough to do this job with a timing belt.

I can change the motor is it's easier to do with an other stepper motor.

What do you think about that ?

Have you carefully read the link you were given in Reply #1? It contains advice on selecting a motor.

If you have built the device, measure the torque required. Then choose the motor.

To measure torque required to turn a shaft, attach a pulley to the shaft, hang a weight from a string and increase the weight until the shaft turns. Buy a motor that can provide at least twice that value.

A brushed DC gearmotor would be much more efficient, easier to control and very likely a better choice. Use a shaft encoder or limit switches to determine the tray position.

Use a DRV8825 driver set to 1.5A. Don't expect more current from a cheap single-chip stepper
driver (except the ones with massive heatsinks).

In NEMA 17 size a 1.5A stepper is the optimum rating to get as it can be driven at full torque from a
cheap DRV8825.

The A4988 isn't quite as powerful, basically they've been superseded by the DRV8825 pretty much.

A L298N is not a stepper driver.
