nema 34 stepper motor: how does it work in CNC machine

nema 34 stepper motor and an encoder can drive the turntable. Six radial holes need to be drilled on one part. He made a total of 3000 holes and 500 holes. This is only the first trial run, and more drilling may be done in the future.
The components discussed are small and light. Instead of using heavy industrial equipment, he used nema 34 stepper motor and Arduino to make an all-electric rotating indexing fixture, which gave him a four-axis rotating fixture.
His idea was to use nema 34 stepper motor directly to rotate the workpiece without any transmission, but he needed to build his own rig to achieve this.
His original prototype used Arduino Uno, and in order to save space, he replaced a Pro Mini in the final version.
Arduino is connected to a solid circuit motor driver. This is the only driver, and in several of his attempts, he managed to keep nema 34 stepper motor with enough torque to prevent the workpiece from moving while drilling.
The number of holes to be drilled is hard-coded in Arduino, so he only needs a button. Every time a button is pressed, nema 34 stepper motor advances 60 degrees and gives it six equal-spaced holes.
He uses the nema 34 stepper motor, which means a strong power supply. He took off the power from an old laser printer, which had 24V DC and 5V output. It was very convenient. The next step is to study mechanical assembly. He machined a tool rod attached to the axle of nema 34 stepper motor.

nema 34 stepper motor: applied in new XY Open Aperture Stage

nema 34 stepper motor is used in AU200-100 x 100 XY Open Aperture Stage. Van Nuys, CA-OES (Optimal-Engineering Systems, Inc.) added a new high-precision open stage on the basis of expanding the XY precision line.
The AU200-100×100 stage is a low-profile stage with only 80mm high and compact footprints nema 34 stepper motor.
The linear travel of X-axis and Y-axis is 100 mm X 100 mm. The resolution of each axis is 20 micron (non-micro-step) or 1 micron (driving 20 micron per step motor in use), the repeatability is 2 micron, and the positioning accuracy is 3 micron.
These stages have pre-loaded V-grooves and cross-roller bearings, and 4 mm grounding screw with a clearance of only 2 microns per ring, all of which help to improve the accuracy and stiffness of AU200-100×100.
It is suitable for laser drilling, mechanical processing, medical, industrial, semiconductor processing, testing, scanning, calibration, assembly and optical applications. This compact, low profile black alumina XY class is easy to integrate into new or existing systems.
Standard two-phase (1.8o) nema 34 stepper motor has knobs for each axis in the manual adjustment phase, but the knobs can be replaced by incremental encoders for position verification.
As an option, servo motors and compatible motion controllers can also be ordered from OES or AU200-100×100 stages as a complete Plug and Play motion control system.
Introduction: OES Optimal Engineering System Co., Ltd. (OES) is a company that produces motion control products. The products include nema 34 stepper motor controller and driver.

nema 34 stepper motor: how to measure it accurately

nema 34 stepper motor is accurately measured. I started by accurately calculating the measurements I needed: the position of nema 34 stepper motor, the case and the nozzle. The nozzle in this position gave me a rough outline of the cold end, so it didn’t hit anything.The other features of the cold end and their location are unnecessary.
You don’t need to model the entire component — you just need to model the parts that affect the component being built. It looks like we have a nema 34 stepper motor bracket at the back.
Since all nema 34 stepper motors are built according to the standard, we can apply Rule 1 immediately. First of all, I chose the angle that was the easiest to measure.
According to Rule 1, I can assume that without rotation, the step mode and everything are completely square.Even though there are some unknown advantages of rotating stepping holes, CAD software hates this kind of thing very much.
If I find a hole offset, the rest can be determined. So I just measured the distance from the edge to the inside of the hole, and then added half the diameter of the hole. If math is difficult, I can do it with zero offset technique.
Finally, we must get the offset from nema 34 stepper motor axis to the center of the nozzle assembly, and the nozzle assembly slides into the cold end.

nema 34 stepper motor: how to improve its performance

nema 34 stepper motor is improved by uStepper to use in items such as inkjet printers – for moving the ink cartridge back and forth over the paper. nema 34 stepper motors can be a cheaper alternative to servo motors, but the drawback of nema 34 stepper motors is not being able to tell if they are moving to the position they were told to move to.
If a person tries to block the path of the ink-jet head, while the printer is printing, it will not recover from this. The same happens in most of the applications using nema 34 stepper motor. uStepper removes this drawback by continuously monitoring where it is, and where it should be. uStepper can compensate if anything goes wrong. It operates with feedback. uStepper has the ability to drive nema 34 stepper motor, monitor position and it has an onboard programmable microcontroller with a wide range of available inputs and outputs.
The new line will offer a uStepper board with improved performance on all parameters, a cheaper lite version and potentially a large and powerful version.
All this is packed into a small printed circuit board that fits on the back of nema 34 stepper motor.

nema 34 stepper motor: suitable for conveyor application

nema 34 stepper motor is an important part of industrial conveyor motion control system. Usually, conveyor applications run at a constant or variable speed, requiring only speed control from the main drive motor. Positioning conveyors, such as conveyors for automatic scales, require more precise control. In these applications, the main drive must start and stop positioning conveyor, with moderate to high accuracy.
DC and AC motors are usually used for speed control of fixed or constant speed conveyors, while stepping motors and servo motors provide more accurate positioning capabilities for conveyors requiring more precise motion.
nema 34 stepper motor is generally controlled by open-loop control, which has the advantages of simple structure, good positioning and economy. But if a feedback mechanism, such as an integrated high-resolution encoder, is configured, the closed-loop nema 34 stepper motor can provide speed and position information to the driver/controller.
Stepper motor suppliers can provide expertise and tools to help you choose the design that suits your application.
The high torque and fast dynamic response of the closed-loop system meet the requirements of high performance positioning conveyor. Speed, torque, accuracy and size are important parameters to be considered when selecting suitable nema 34 stepper motor for conveyor application.

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 34 stepper motor: used in a piece of art

nema 34 stepper motor and STM32 are good components. In the life of ordinary cars, the dashboard is basically unaffected. Apart from occasionally wiping with wet cloth, they are usually reliable in terms of car life, and as they grow older, they are also difficult to repair. However, some hackers find themselves fiddling with them and learn skills in the process, such as how to control nema 34 stepper motor and talk to CAN buses. After doing some projects in the past, Dan had some old tachometers lying around and decided to turn them into a work of art. The construction is driven by STM32 – a powerful arm based platform with a large number of IO and potential. Dan Using its function, the board generates music and responds to the data of the accelerometer on the board, while driving nema 34 stepper motor from the old tachometer. The project was then completed through a 3D printing installation board, and the tachometer components were placed on the back of IKEA canvas printing.
The end result is a work of art on the wall, which produces strange string music while convulsing. It comes from Dan’s project before using dashboards. This is a very interesting hacking skill, but we think there is still greater potential. There are a lot of projects that can benefit from lightweight micro actuators. We want to see a robot consisting of STM32 and nema 34 stepper motor.

nema 34 stepper motor: works well in a laser plotter

nema 34 stepper motor is applied in a laser project. Tucker Shannon invented a machine that uses lasers and some ultraviolet-sensitive paper to draw temperature and weather icons! According to Tucker Shannon’s previous work glowin-in-dark drawing, the brain inside the machine is a Raspberry Pi Zero. The laser itself is a 5MW, 405nm laser pointer with a button zipper. Two nema 34 stepper motors are used for laser orientation, one for rotation and one for height angle. Each nema 34 stepper motor is connected to a motor drive plate and connected directly to Pi.
The real beauty of Tuker’s laser plotter is that it can draw temperature and weather icons, as well as digital or analog time! The precursor to this project is his clock, which draws time using a robotic arm with a UV LED, while the other clock uses a laser-connected analogy.
The base and arm of laser were designed in SolidWorks, and then 3D printing was done. The battery has been removed from the laser and the terminal is connected directly to the raspberry pie. Pi connects to Alexa through IFTTT, so that it can control it anywhere. nema 34 stepper motor is installed vertically and the laser pointer is installed at the end.

nema 34 stepper motor: how to get the feedback

nema 34 stepper motor is a hybrid stepper motor, it is available in different lengths to suit different applications. In this article, we are going to talk about how can we get feedback from a nema 34 stepper motor.
Usually we use CTs to check the state of nema 34 stepper motor, but stepper motor is usually small DC motor, Hall effect sensor can not be very good telescopic. Another way to use automation is terminal switches. Rotary actuators usually have a set of NO / NC contacts that change state at preset angles (such as 5 or 85 degrees). Some also provide analog output back to your controller, so in the initial command 10Vdc to the analog input terminal, the actuator will produce a steadily rising analog output back, depending on the actuator’s current position as it rotates to full.
So the series of cams on the output shaft of the Nema 34 stepper motor and the instantaneous roller switches spaced around it will give you a set of binary shaft positions as feedback.
Do you want a more fluid analog? You can also set up an IR transceiver aligned with the reflector on the output axis and use counter IC or accumulator logic to determine the number of rotations or the speed of rotation. In particular, add a gradient to the IR reflective band of the rotating shaft, then the IC can now tell you the current shaft position and rotating speed of nema 34 stepper motor.

nema 34 stepper motor: is it better than other stepper motor?

nema 34 stepper motor is larger than other stepper motors, and the new nema 34 frame (86 mm x 86 mm, 6, 0 nm) stepper servo integrated motor has been released by Applied Motion Products. The nema 34 stepper motor can be installed in more demanding applications requiring greater torque.
Available in four lengths, the nema 34 stepper motors offer machine designers a range of torque values to choose from. The longest motor (-6) provides a holding torque value of 82 nm and a peak torque value of over 92 nm. The TXM34 integrated motor is rated at ip65, all connected to the M12 connector and the front axle has a shaft seal. The TSM34 and TXM34 integrated motors support various control options, including step direction, speed, and series command mode. They also support the implementation of stored programs using the Q programming language of Applied Motion.
The nema 34 stepper motor consists of two power connections, a mains supply and an auxiliary supply, so that themotor supply can be removed while maintaining the controller and communication power. This feature eliminates the need to reinstall the system after an emergency stop event, which for many applications can provide the same end result as using a motor with an absolute encoder. In addition to the traditional star network topology, the nema 34 motor can be connected to a line network topology.
