nema 17 stepper motor: how to use it easily for beginners

nema 17 stepper motor is more difficult to use, especially for beginners. But with a huge 3D printing nema 17 stepper motor, Proto G makes your electronic commutator motor easier.
Although we’ve seen 3D printing stepper motors before, their size and simple layout really help us understand this theory.
In fact, nema 17 stepper motor cost $14 on Adafruit, and there are a large number of residual motors of all shapes and sizes, which are cheap, so your own motors won’t be cost-effective for a long time. Once again, if we are to unleash the full potential of additive manufacturing and start the industrial revolution of de-centralization, understanding the working principles of complex mechanical and electrical equipment such as step-by-step will be the key to developing on-demand manufacturing processes.
This is a 3D printing frame, coils wrapped around nails, rare earth magnets sticking to the rotor, this is an approachable construction, the interior of a stepper motor, so that everyone can see and understand.You can easily observe how the rotors are arranged when different coils are electrified in circular mode, although it may be more enlightening to include a two-color led to indicate which coils are electrified and what polarity is. These will help to demonstrate the concept of half step. The Proto G project will not allow you to launch available nema 17 stepper motor from 3D printers in a short time.

nema 17 stepper motor: can be customized

nema 17 stepper motor is applied in different projects, but gearboxes are usually required, especially in applications such as CNC machine tools and linear drives for 3D printers. A high torque, low backlash gearbox may be the most appropriate choice among these mechanical devices, and a 3D printed detachable planetary harmonic drive for the nema 17 stepper motor may be better.
This nema 17 stepper motor drives a solar gear with two planetary gears, each with a 56-tooth stationary ring and a 58-tooth output ring. Each rotation of a planet around a fixed ring causes the output ring to rotate one tooth, resulting in a reduction of nearly 100:1.
We think the “harmonic” name on this gearbox is a bit of a misnomer because the definition of the harmonic drive seems to be the periodic deformation of the curved spline, as we saw on this 3d printed strain wave gear. No matter what you call it, it’s pretty cool and can be a handy tool for all kinds of builds.
We will say that we suspect that any plastic gearbox can keep bouncing free. But we can see the benefits of design. It has some good functions. First of all, of course, it is printed entirely on 3D, except for a few screws. The perfect combination with the nema 17 stepper motor is also a very good feature, and the design on Thingivers should not be too difficult, so it can not be up and down scalable.

nema 17 stepper motor: the reason for using H bridge IC

nema 17 stepper motor has one winding in each stator phase. A biphasic bipolar nema 17 stepper motor will have 4 leads. In bipolar stepper motors, we do not have a common lead like a single pole stepper motor. Therefore, there is no natural reversal of the direction of the current through the winding.
The bipolar nema 17 stepper motor is convenient to operate, but the operation is complex. In order to drive the bipolar stepper motor, we need a built-in H bridge circuit driver IC. Since the current needs to be reversed to reverse the polarity of the stator pole, this can only be done through the H bridge. There are two other reasons for using H bridge IC:
1. nema 17 stepper motor has quite high traction at present. SCM pin can only provide 15mA at most. The current required by the stepper is about 10 times that of this value. The external drive IC can handle such a high current.
2. Another reason for using the H bridge is that the stator coil is only an inductor. When the coil current changes direction, a spike will be generated. An ordinary microcontroller pin can’t stand such high spikes without damaging itself. Therefore, in order to protect the microcontroller pin, the H bridge is necessary. In most nema 17 stepper motor interface projects, the most commonly used H bridge IC is L293D.

nema 17 stepper motor: easy to install in AD88 3D printer

Nema 17 stepper motor is used in my own first 3D printer.
The AD88 3D printer is in the prototype designed by me in the tinkercad modeling program from 0.
Why did I do that?
I’ve always drowned a 3D printer, but we all know how hard we find them and at what prices.
7 months ago my brother bought such a printer after 4 months of intensive work. He recently had a problem with him and was forced to buy the piece at a printer (extruder). This is where I came up with the idea of building my own 3D printer.
I’m interested in the internet but I have not found an easy-to-use printer model with the materials I have at my disposal, so I decided to design my own printer.
After many hours in front of the calculator I managed to create prototype AD88 with nema 17 stepper motor.
Right now I do not know if this prototype will work just like a printer but I hope my measurements and my imagination have helped me.
Now that I learned where the idea of this project came from, let me tell you how she got this name. This printer, without realizing it, was designed on 08/08/2018. So I decided that her name would contain 8, and AD comes from my brother’s initials who helped me with my parts and my homework.
For this project we needed:
-4 nema 17 stepper motors from STEPPERONLINE
– about 1 kg of filament.
– threaded bar with thickness of 8mm and 3m.
– fine bar 8mm thick and 1m long.
– 12 linear rollers
– Two pulleys
– 2m GT2 toothed belt
– Extruder
– the drivers
– Three buttons
– and other improvised material.
– 2 threaded rods
– 50 nuts 8mm
Once all the materials have come, I will come back with the novelty and programming code, respectively the program.
If there are some improvements to this prototype, it can have a much larger print distance, much better precision and stability. This is version 1.0. And now I understand that it is not so easy to project anything from 0, especially if you have no idea what design means.
After I temporarily mounted the frame I notice that it has small design faults, in the sense that some parts should have been larger and others could have been smaller.
Finally, I will be happy if my prototype with nema 17 stepper motor will be able to print at least simplistic things.

nema 17 stepper motor: works great in my syringe pump project!

Nema 17 stepper motor is quite useful for my project. My project uses X-ray microfocus radiography to monitor the changing displacement patterns and saturations of Berea sandstone rock samples while undergoing water alternating gas injection coreflood experiments. Water alternating gas (WAG) injection is commonly conducted in enhanced oil recovery of partially depleted oil and gas reservoirs. Alternating slugs of water and gas are injected to displace remaining oil trapped in subsurface reservoir rock. However, gas flow often associates with fingering due to high gas mobility, which leaves a large portion of the reservoir unswept. Many mobility control agents have been proposed to curb the high gas mobility and hence improve the efficacy of the WAG technique (Fig. 1). The agents are aimed at decreasing the permeability and/or decreasing the apparent gas viscosity; examples include foams, polymers, and nanoparticles. My study primarily focuses on the use of foam as a mobility control agent for conformance improvement.

The experiments are conducted within the X-ray cabinet. X-rays are perpendicularly passed through the rock sample during the WAG coreflood experiments and images are taken (Fig. 2). Analysis and processing of these images will allow us to visualize the changing displacement patterns and saturations of the rock sample as alternating slugs of water and gas are injected. The X-ray machine itself is a shielded enclosure, providing a physical barrier between damaging radioactive X-rays and the outside environment. This means the X-ray cabinet is a self-contained and closed system. Any pumps or tools placed within the X-ray cabinet can only be powered from within the X-ray cabinet.
For our application, a 20V battery is used to power the injection syringe pump and is placed along with the rest of the fluid injection setup within the X-ray cabinet. Once the interlocks of the X-ray cabinet are secured, which is the only way for X-rays to be generated, we will not have access to the interior of the X-ray cabinet. Thus, the pump must also be able to be remotely controlled via Bluetooth. An android phone or computer is used to wirelessly operate the fluid injection apparatus via an Arduino Uno and HC-06 Bluetooth module. Pictures of the automated fluid injection setup along with the syringe pump is shown in Fig. 3. More pictures of the syringe pump is shown in Fig. 4.

The syringe pump is able to inject at pressures as high as 100 psi and at flow rates as low as 1 cc/min. Total injection volume before having to disassembly the pump and refilling is approximately 100 mL. The components for the syringe pump are listed below:
1)NEMA Motor: A nema 17 stepper motor with a gear ratio of 100:1 is used to achieve the required torque and speed. With a 48mm body and 1.68A rated current, the motor purchased from STEPPERONLINE is very suitable for an application that requires low speed and high torque.
2)Electronics: The various electrical components achieve flow automation, data logging, and stepper motor control. For flow automation, an android phone or computer is used to wirelessly operate the fluid injection apparatus via an Arduino Uno and HC-06 Bluetooth module. For data logging, pressure and temperature monitoring is accomplished through a DS 3231 Real Time Clock module, ADA254 Adafruit Micro-SD Breakout Board, and 100 psi Autex pressure transducer. For stepper motor control, a separate Arduino Uno and HC-06 Bluetooth module are used, along with a Big Easy Driver. Electronics purchased from various vendors including Amazon, SparkFun, and Adafruit.
3)Motor Mount: A 3D printed part to securely hold the NEMA motor in place. Printed in ABS (Acrylonitrile Butadiene Styrene) thermoplastic.
4)Shaft Coupler: Purchased from STEPPERONLINE, the 8mm-8mm Flexible Coupling 18x25mm CNC Stepper Motor Shaft Coupler connects the stepper motor to the threaded rod.
5)Syringe Plunger Mount: This 3D printed part with a M8 nut embedded inside is used to translate the rotational movement of the stepper motor and the attached M8 threaded rod to the translational, horizontal movement used to push or pull the syringe.
6)Syringe Plunger: The stainless steel part of the syringe that pushes against the liquid residing in the syringe barrel.
7)Syringe Barrel Holder: This 3D printed part holds the syringe barrel.
8)Syringe Barrel: The stainless steel part of the syringe that holds the liquid.
9)Syringe Tip Holder: This 3D printed part rests against the syringe tip. Only the syringe tip holder has to be unscrewed and removed in order to refill the syringe barrel.
10)Mounting Rail: Components are mounted onto an 18-inch piece of 1″x2″ 80/20 extruded aluminum rail, which makes the design modular and space-efficient.
11)M8 Threaded Rod: Turns with the stepper motor.
12)Smooth Rod: Two smooth rods hold the separate components in place.
Both the nema 17 stepper motor with a gearbox for higher torque requirements and the specific shaft coupler were components I had a hard time finding a vendor for. That is until I stumbled upon STEPPERONLINE. Their very large catalogue of NEMA motor models and other accessories made it an ideal vendor to purchase from. After dozens of experiments with nearly hundreds of hours of use, the components purchased from STEPPERONLINE continues to function very well. Superb quality nema 17 stepper motor at a very reasonable price.
