Stepper DriverAhmad


Stepper motor drivers are specifically designed to drive stepper motors, which are capable of continuous rotation with precise position control, even without a feedback system. The usual stepper motor drivers offer adjustable current control and multiple step resolutions, and they feature built-in translators that allow a stepper motor to be controlled with simple step and direction inputs. These modules are generally basic carrier boards for a variety of stepper motor driver ICs that offer low-level interfaces like inputs for directly initiating each step.

Types of Stepper Drivers

There are different types of stepper motor drivers. Here are the three main versions that you will come across-

  • L/R Stepper Motor Driver: This type of stepper motor driver carried out rotations at a low to medium speed and this can result in fairly limited ranges of power output. They can still offer a full rotation but they don’t usually offer control in regards to variable current levels.

  • Chopper Stepper Motor Driver – Micro-step: These types of stepper motor drivers are able to use a micro step mode. This means that it runs smoother and more efficiently as the current rate is regulated at all speeds. It works on a solitary supply of high voltage and has output transistors that have come on and off automatically.

  • Bi-level Stepper Motor Driver: The third type of stepper motor driver is the bi-level and this can use both high and low-level voltages. It works by powering up to a high rate of current and when it reaches the level that you need, the high voltage is turned off. The low voltage is then used to maintain this level of supply when it is in use.

Specifying stepper drives

  • select a stepper with at least twice as much torque as required at the target operating speed, and use a motor rated at about ¼ supply voltage.

  • The driver should output at least 1.4 times the motor’s rated current. Choose a driver that has several step resolutions to test different microstepping settings to get the smoothest motion. Finally, make sure the driver can receive enough step pulses to rotate your motor at the desired speed. Sometimes drivers are limited to something small like 10 kHz. If you’re hoping to microstep even at 8× with a 1.8° stepper, your maximum revolutions per sec speed is 10,000/(8 × 200) = 6.25 rps.

  • To make a stepper motor run, we need to use possibly a A4988, a DRV8825 or possibly a Trinamic TMC2130 or similar categories.

Best CNC Stepper Motor Drivers for Every CNC Application:

Here are the best Stepper Drivers available today [2021] for CNC applications:

  • SongHe DRV8825 Stepper Motor Driver (Recommended): This CNC motor controller can run a 1.5 A NEMA 17 motor reasonably well and obviously any stepper motor that’s smaller than that. While the A4988 can do up to 1/16 microstepping, the DRV8825 can do up to 1/32 microstepping, making the motor movement smoother. The Songhe DRV8825 ships with aluminium heat sinks included. Adjusting the current from the driver in DRV8825 is very similar to that of the A4988, by doing a potentiometer adjustment.

  • StepperOnline DM542T Stepper Motor Driver: This stepper driver can power almost any NEMA 17 and NEMA 23 motor, except probably the high torque NEMA 23 with 4.2A. The driver an excellent choice for almost any GRBL based DIY CNC project, including the large 8’ x 4’ frames. The heat sinking and cooling on this motor is excellent. It is a very silent driver and it doesn’t sweat even when you hit 4A.

One important difference between the G540 and the other steppers is that it is run on Mach3/4 and LinuxCNC instead of GRBL and operates via a parallel port to connect to the CNC controller.
