nema 23 stepper motor: what’s the system of it

nema 23 stepper motor has several coils, which must be electrified in a specific order to rotate the motor in each step. Typical nema 23 stepper motors move 1.8 degrees per step, equivalent to 200 steps per 360 degrees of rotation.
Some nema 23 stepper motors move in smaller steps to provide more accurate positioning. For example, rotate 400 steps per 360 degrees and 0.9 degrees per step.
nema 23 stepper motor is a good fit for many linear manufacturing processes because of their repeatability, high torque at low speeds, and minimal maintenance requirements. Common linear positioning applications include conveyor belts, orbit positioning and X-Y tables.
nema 23 stepper motor can also work well in rotary motion applications due to their general installation options, repeatability and reliability.
Common rotary applications include indexing tables, length-cut machines and labels. The unit receives instructions directly from the PLC and works well with a wide range of nema 23 stepper motors.
The combination of controller and driver is a good choice. Motion control applications involve multi-axis stepper motor control, because there are versions on the market that deal with up to six-axis motion control.
Whether it is the choice of individual components or combination units, PLC or PC still need to provide supervision, control and coordination. Most nema 23 stepper motor is equipped with PLC.

nema 23 stepper motor: hydraulic and electric analogies

nema 23 stepper motor has a simple premise from the user’s point of view: we want to send a series of electronic pulses, each pulse will lead to a change in the specific angle position of the output shaft.
For example, we might want a pulse train consisting of 52 pulses to precisely change the axis angle by 52 degrees.
Accurate incremental segmentation requires precise control and coordination of piston pressure. In this case, the resolution of nema 23 stepper motor system is 1 degree Celsius per input pulse.
Then, through the screw, rack, pinion or other rotary to linear converter, the linear position can be achieved without the need for closed-loop feedback control system.
When the controller is composed of a simple on-off valve system , the resolution of the system is 90 degrees./Pulse (valve shift operation, one at a time).
A more sophisticated electronic control method is needed to achieve so-called micro-stepping. The simple geometric structure of hydraulic nema 23 stepper motor is mainly composed of non-concentric but circular rotor cam and 90 degree angle.
Piston displacement, suitable for sinusoidal and cosine wave excitation, to achieve micro-step and optional continuous rotational motion, with traditional motors. Overall, hydraulic nema 23 stepper motor is very similar to electric nema 23 stepper motor.

nema 23 stepper motor: how does it work in 3D printers

nema 23 stepper motor is an important part of a 3D printer. Normally, your regular desktop 3D printer is a bunch of belts, screws and pulleys. DeepSOIC completely eliminated them. How did he do it? nema 23 stepper motor linear actuator is used.
Search Google for “linear stepper motors” and you’ll find a bunch of linear motors with screws in the middle. This is not a linear stepper motor. This is a stepper motor with a lead screw in the middle. DeepSOIC thinks of engines that are more like a mixture of rack and pinion gears and maglev trains.
The “straight line” part of the nema 23 stepper motor is a magnet track perpendicular to the motor axis, which has alternating polarity. It’s basically an unrolled nema 23 stepper motor that can run 3D printers faster without too much mud and clearance.
At present DeepSOIC is in the experimental stage, and he plans to print the axis of his linear stepper with a ferromagnetic wire. It doesn’t work. The permeability of the steel found in the motor is about 4000, while the permeability of his brand ferromagnetic wire is about 2. It was a great success in describing the performance of magnetic 3D printing filaments even though the idea of printing nema 23 stepper motor parts was completely unsuccessful.

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 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.

nema 23 stepper motor: why does it used in various types of applications

nema 23 stepper motor is often mistaken for servo motor components, but in fact, nema 23 stepper motor is as reliable as servo motors. The stepper motor achieves highly accurate positioning and speed control by precisely synchronizing the pulse signal output from the controller to the driver. nema 23 stepper motor has the characteristics of high torque and low vibration at low speed, which is suitable for short distance and fast positioning.
Suitable application
In addition to frequent start and stop point applications, nema 23 stepper motors are suitable for locating image processing processors that do not like vibration, cam drives that are difficult to adjust for servo motors, and low-rigidity mechanisms such as belt drives. In addition, by changing the ball screw drive to belt drive, the cost is greatly reduced.
High responsiveness and excellent synchronization
The notable feature of stepper motor is responsiveness. The open loop control sends one-way commands to the motor and has a high tracking mechanism for the commands. When the servo motor waits for the feedback of the encoder, the command is often “delayed”, while the stepper motor works synchronously with the pulse. Therefore, there is little “delay”, so the response is very good. Thus, nema 23 stepper motor is suitable for applications requiring synchronous operation of multiple motors.

4. The speed response performance is different, nema 23 stepper motor needs hundreds of milliseconds from the standstill acceleration to the working speed, and the servo system has better acceleration performance, generally only a few milliseconds, and can be used in control occasions requiring fast start and stop.
5. The overload capability is different, nema 23 stepper motor generally does not have overload capability, and the servo motor has strong overload capability.
