nema 23: how to make analog clock with it

nema 23 is used in an analog clock. This “antique” automatic correction analog clock was designed by Instructables user gzumwalt.
Previous clocks used spring-driven mechanisms, while gzumwalt clocks used Adafruit Feather ESP32 and nema 23. Before assembling printed parts, test their suitability and file or polish them as much as possible to promote smoother movement. Make sure that all edges in contact with the printer plate are smooth.
Special attention should be paid to moving surfaces, such as gear teeth, and eliminating any “dirt” in plate making. For threaded parts, taps and dies may come in handy, mainly because the clock relies on threaded parts. Once you’ve done this, here’s a general overview of the assembly steps:
1.The reed switch enters the 3D printing bracket. This component is fragile and needs to be handled with care. For example, only bent reed switch wires use high-quality pliers to reduce the possibility of fracture.
2.Adafruit demonstrates how to use socket connectors to assemble featherboards.
3.Connect Adafruit feather plate to reed switch and nema 23 controller. You will weld, but also use screws and nuts to connect these three components.Most importantly, you need to know which wires go where during welding, because you can’t confuse polarity.
Keep in mind that the Adafruit feather board and nema 23 controller will be attached to the side that cannot accommodate the gears.

nema 23: how to drive mechanisms in cost-sensitive applications

nema 23 is applied in many machines, the one designed for economic reasons can provide better user experience if they are quieter, smoother and more energy-efficient.
Millions of small electronic devices with built-in motor drive mechanism are used everyday around the world, relying on stepper motors to achieve low-cost motion, which can be easily controlled without complex microprocessor-based driver.
These include multifunctional office printers/scanners, cash machines, point-of-sale terminals, sewing machines and many industrial applications.
nema 23 is an attractive solution for driving mechanisms in cost-sensitive applications such as office machines, trading equipment and some types of industrial machinery.
In order to meet the demand of the market for better performance and availability, two key aspects of motor control strategy are strengthened under the economic price. Energy efficiency is improved, heat generation is reduced, and operation is quieter and smoother.
The audible noise emitted by nema 23 can distract attention, especially in industrial scenarios where a large number of motors may operate simultaneously in the same area.
In addition, even at low speeds, drivers consume electricity, which is often inconsistent with ecological design goals and may endanger the battery life of handheld applications.
Therefore, in many cases, nema 23 is most suitable for all kinds of requirements that must be met, but it is not a perfect or ideal solution.

nema 23: how to make a Euroack sequencer with it

nema 23 is a part of Eurorack sequencer module. Eurorack has taken over the synthesizer community and hundreds of people are building their own Eurorack modules. Michael Forrest designed and built his own Eurorack sequencer module, which does not use strange things like capacitors and chips to store signals.Instead, he did it with nema 23 and some ingenious engineering.
The basic idea of Eurorack sequencers is to store a series of values in some way and play them over and over again. Connect this sequence to a clock and you can get the same sound pattern from the synthesizer. This can be achieved through a circular buffer, using a bunch of FETs and caps in the analog domain, or, in this case, sticking to a piece of paper on nema 23.
The key of this structure is the stepper motor with 96 steps per rotation. This is important because the module is controlled by clock pulses from the sequencer.
Because 96 can be divided by 8 and 16, this means that the sequencer will play in 4/4 of the time.
The built electronic device is very simple. Arduino receives clock pulses and sends step signals to H-driver. It’s very simple, very interesting, and it’s installed on a suitable eurorack-sized panel. nema 23 rotates a paper disc, which is read out by a photoresistor and an LED.

nema 23: how to make a 3D printer with it

nema 23 is used in a H Series hybrid 3D printer CNC machine. The design of the H series reflects the need for mechanical systems to withstand higher loads than typical printers.
For the H series adder, the saddle/y axis/bed assembly has the lowest mass.This corresponds to the mass of a typical double extrusion gantry assembly. The X-axis drives the whole assembly, using a higher torque nema 23 and a 9mm GT2 belt drive. The size of wire also reflects the stress of each axis (Y axis is 8mm, X axis is 16mm).
The turret/arm assembly moves only in the Z direction, and its high quality is offset by the balanced weight in the column.The z-axis is driven on the 16mm axis, using nema 23 and 5 mm pitch pre-tightening ball screw.With this setup, we can perform fast Z motion and very small deflection.
All of these indicate that the H-series augmenter meets the standard of the best printer of its kind. If the question is: How good is the H-series mixer compared with a typical FDM printer? This is not a comparison.This hybrid machine tool is strengthened to handle machine acceleration and tool load.The X-axis and Z-axis are supported by a line axis, and the y-axis is increased to 16 mm in diameter. The X and Y axes are driven by pre-installed high-lead ball screw and nema 23.

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 23: applied in space flight

nema 23 can work in harsh environments and inherent problems in outer space motion control. The stepper motor is assembled according to AS9100 standard, tracing the origin of each component, and strictly controlling the manufacture to the final product.
Most of the components on nema 23 are metal alloys, which are not painted and can be used in vacuum. Plastic materials should be non exhaust polyamide or nylon. Sealed bearings filled with low exhaust lubricants are also acceptable. The stepper motor winding is optimized to minimize the resonant frequency at a specific operating speed. The use of components with high concentricity and dimensional accuracy helps to ensure that the rotor or shaft does not bring unnecessary vibration to the system. In space, vibration must be avoided because they affect sensors and instruments on board ships; low-level oscillations affect the quality of measurement sensors and imaging equipment. Because spacecraft or satellites have no energy to transfer in space, restraining vibration is a challenge. Each nema 23 designed for space requires the integrity of the material structure to deal with the expected forces without changing dimensional accuracy or mechanical integrity. Launching spacecraft into orbit is very violent, because the components are exposed to high amplitude vibration, low amplitude vibration and multi-direction impact. In addition, nema 23 vibrates during normal operation.

nema 23: what is the technical explanation of it

Nema 23 is a DC motor that rotates discontinuously. Instead, a complete rotation is divided into several equal steps. Nema 23 consists of multiple stages, which are composed of multiple coils. Nema 23 rotates one step at a time by applying the energy of the input voltage to each phase in a sequence. Therefore, nema 23 converts electrical energy or input digital pulses into mechanical shaft rotation.
Nema 23 work on the principle of electromagnetism. The rotor uses permanent magnets or soft iron as the rotor, and the rotor is surrounded by an electromagnetic stator. The poles of the rotor and stator can be fixed with sharp teeth. When a voltage is applied across the terminals, the rotor is aligned or moved to the stator with minimal clearance due to magnetic effects.
The stator is energized in a certain sequence, and the rotor is also rotated to fully rotate it, and is divided into discrete steps at a specific step angle.
Nema 23 are used in equipment that requires precise positioning and speed control. Because nema 23 can accurately repeat the movement, it is used in 3D printers, camera platforms, plotters, scanners and other equipment. Due to its maximum torque at low speeds, nema 23 is also used in equipment that requires low speeds.

nema 23: what’s the advantage of it

Nema 23 consists of a rotor with permanent magnets and a fixed stator with a winding. When the current flows through the stator winding, it generates a flux distribution that interacts with the rotor’s magnetic field distribution to exert a steering force.
Nema 23 has high magnetic pole counts, usually 50 or more. The stepper motor driver charges each pole in order, so that the rotor rotates in a series of increments or steps. Because the poles are very high, the motion seems to be continuous.
Nema 23 has many advantages. Because they generate incremental motion, they usually run open-loop, eliminating the cost and complexity of encoders or parsers. The high pole count allows them to produce very high torque at zero speed. They are compact and economical.
In adverse aspects, nema 23 has speed limits. They usually run best at 1200 rpm or below. Although they produce high torque at zero speed, the torque decreases with the increase of speed. For example, a motor that produces 100 ounces of inches at zero speed may produce only 50 ounces of inches at 500 rpm and only 10 ounces at 1000 rpm. If nema 23 is used to drive ball screw actuators or similar, it may not provide enough speed to meet the needs of the application.

nema 23: operates fine in a new linear robot

nema 23 is used broadly in robotics. Easily and accurately move in the smallest space. These are the requirements of linear robots, such as automated tasks used in processing areas and test automation.
In order to produce products at a lower cost in the shortest time, the automation of the production process is increasingly important for mechanical engineering. For this reason, igus said they have developed a new compact linear robot with nema 23.
Alexander Muhlens, director of drilin transmission technology planning at igus, explained: “Two drilin ZLW belt shafts and one drilin GRW rack shaft ensure precise guidance and lubrication through sliding elements made of high performance plastics.” The system configuration file for mounting bracket can also be used as an option. The linear robot is delivered within 24 hours, ready to connect nema 23 and encoder. Therefore, customers can install products on the machine the next day.
Drylin linear robot for instant use
In addition to the new DryLin E-line robots used in a small work envelope, igus also provides line and plane-line robots directly from inventory. All linear robots include pre-configured DryLin linear modules, all the components and linear shafts with nema 23 required for self-assembly.
