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.
