nema 23 stepper motor: works in extremely hostile conditions

nema 23 stepper motor is designed to provide calibration and accurate motion control and is widely used in daily industrial applications, some of which may be quite surprising.
For example, today’s air conditioning systems in automobiles can install up to 30 or more bus controller stepper motors, which have precise automatic temperature setting. These are used to precisely control the opening of the air conditioning flaps around the vehicle to ensure correct cabin temperature. Now, consider the number of vehicles outside, and you will know the huge number involved.
Waterproof stepper motor
nema 23 stepper motor needs to run at least 30 feet deep and is truly waterproof. The motor uses shaft seals, O rings, sealed cable feeds, pressure balancing and other functions. The main problem is that the standard nema 23 stepper motor is wound with copper wires coated with enamel or varnish.Even if the coating process is good, there will always be small pinholes on the varnish.
Space and underwater motors
Stepper motors work in vacuum or radiation sensitive environments.They need to work at extreme temperatures in outer space, such as at low temperatures. Finally, nema 23 stepper motor need to be waterproof to resist the presence of water, moisture and solvents.

nema 17 stepper motor: how to make a 3D printer with it

nema 17 stepper motor is used for a 3d printer. Obviously not the toy itself. Lego 3D printers can actually pump out some credible 3D models for you. Based on the Prusa I3 rework printer, the machine is matched with nema 17 stepper motor.
Although most Lego printers use servo systems, this design works well with stepper motors.
From Instructables member Gosse Adema, we can work according to the assembly mode of X-axis, Y-axis and Z-axis, which is characterized by using the default 4*2 Lego building blocks on the basis of 32 X 16 X 9.6 mm.
Once you have established a base, you will think:
1.The Y axle Y bearing housing is equipped with motor and belt to place LM8UU bearings, and there are 21.25 studs from 170mm. Use the technical brick on the back of the machine to place nema 17 stepper motor.
2.Start building frame and assemble Z axis with stepper motor and threaded rod.
This determines how high you can print, but don’t build it too high.
The higher the frame, the more unstable it is.
3.The Nema 17 stepper motor is attached with 2 x 4 and 2 x 8 orifice plates.
4.Complete X-axis and stepper motor-instructions must be carefully participated in this section as Adema warns that this is the most difficult step, including images when you complete each step with nema 17 stepper motor shaft, and belt-starting right and then left.

nema 23: used in a CNC router

nema 23 is used in a homemade CNC machine. Koopman has been wandering around the Internet for some time to check the CNC machine tools that he has done. He wants to build one.In his search, he noticed that there was a common clue between home-made machines. They are usually made of readily available or readily available components.
He had some parts to deal with, so he decided to jump onto the band’s carriage and make a CNC router. The difference between Kupman’s project and other projects is that there are obviously some very good components in his parts box. The machine has a nickname “Tweakie” because it will never really be finished and there is always a way to make it better.
Cooperman also thought about this, so he fixed the aluminium gaskets on the steel frame and folded them flat. After that, THK linear bearing is fully supported to connect to the surface of the straight gasket. Both the X and Y axes have ball screws to reduce the rebound and are driven by nema 23.
Mach3 is the software that controls CNC routers. All electronic devices are neatly mounted in an electrical cabinet mounted on the back of the machine. It communicates with a three-axis nema 23 driver board through parallel port, which can provide 24VDC for nema 23.

nema 34 stepper motor: how to reduce the heat of it

nema 34 stepper motor sometimes generates heat. Although stepper motor heating generally does not affect the life of the motor, but in some cases it will bring some negative effects. For example, some occasions do not allow excessive heating of the motor, such as medical devices and high-precision testing equipment. Therefore, the necessary control should be made for the heating of nema 34 stepper motor.
To reduce heat is to reduce copper loss and iron loss. There are two directions to reduce copper loss, reducing resistance and current. This requires that nema 34 stepper motor with small resistance and rated current should be selected as far as possible in the selection of type. For the selected stepper motor, the automatic half-current control function and off-line function of the driver should be fully utilized. The former automatically reduces the current when the motor is in static state, while the latter simply cuts off the current. In addition, due to the nearly sinusoidal current waveform and less harmonic, the subdivision driver will have less heat.
For all nema 34 stepper motors, the inside is made up of core and winding coils. The winding has resistance, the power will produce loss, the size of loss is proportional to the square of resistance and current. The core has hysteresis eddy current effect, it will also produce loss in alternating magnetic field, its size and material, current. Frequency and voltage. This is called iron loss. Both the copper loss and the iron loss will be manifested in the form of heat, thus affecting the efficiency of nema 34 stepper motor.

nema 17: essential component of the new motor

nema 17 and six controllers of different industrial Ethernet protocols, absolute multi-loop encoder, closed-loop and M12 connector compose the new ServoStep integrated stepper motor. This new nema 17 is based on the latest microprocessors and cooling technology and advanced design than before.
All the necessary electronic components in the stepper motor system are integrated in the motor itself, and are similar to other JVL motor concepts, so they are easy to use in various motion control stepping motor or servo motor applications. New nema 17 contains everything needed to solve modern control tasks, whether as an independent and self-programmable motion controller or from external PLC or PC control.
Industrial Ethernet:
Profinet, EtherCAT, Powerlink, EtherNet/IP, Modbus TCP or SERCOS III can be used, and synchronization and driver profiles of EtherCAT and SERCOS III can also be used.
MACtalk can use Ethernet to debug the motor, so there is no need for RS232/RS485 converters or extra cables.
Because of scalability, the JVL industrial Ethernet module is also a “proof of the future” because the new version of the protocol will always be suitable for design. New nema 17 is equipped with two Ethernet connectors and a built-in switch, so that the circuit topology does not require any additional expensive hardware.The new nema 17 can be upgraded at any time by using other protocols or updated versions of the same protocol.

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 23 stepper motor: what’s the microstepping myths of it

nema 23 stepper motor decomposes a complete rotating process into hundreds of independent steps, which makes them ideal tools for precise motion control, whether in automobiles, robots, 3D printers or CNC machine tools.In DIY projects, 3D printers and small CNC machine tools, most of the stepper motors you will encounter are bipolar, two-phase hybrid stepper motors, 200 steps per turn or higher resolution, 400 steps per turn. This leads to a step of 1.8 degree angles of 0.9 degrees.
To some extent, steps are pixels of motion. Usually, a given physical resolution is not enough. In the full step mode, hard switching of the coil (wave drive) of the stepper motor will cause the motor to jump from one step position to the next step position, resulting in overshoot, torque ripple and vibration.In addition, we also want to improve the resolution of nema 23 stepper motor in order to get more precise positioning. Modern nema 23 stepper motor drive has the characteristics of micro-step. This driving technology can squeeze any number of micro-step into every complete stepper motor of the motor. It can significantly reduce the vibration and (it is said) improve the resolution and accuracy of the stepper motor.
On the one hand, the micro step is actually the step of nema 23stepper motor, even under the load. On the other hand, they usually do not increase the positioning accuracy of nema 23 stepper motor.
