Q:Step 2: what does the 5 phase mean
There are three types of stepper motors: permanent magnetic (PM), reactive (VR) and hybrid (HB). The permanent magnet step is generally two phases, the torque and volume are small, the step Angle is usually 7.5 degrees or 15 degrees.
Q:Step 6/1.2 step motor. How many pulses do you need to turn a circle without segmenting?
The pulse frequency is 20K, which is 20000P/S, and the subdivision 1000 is 1000P/R (P for pulse). So you take 20,000 divided by 1,000 is equal to 20, which is 20 times r over S, which is 20 times 60, which is equal to 1200R. If you want 260R/MIN, this number is not divisible by 60, so your pulse frequency is not good, it's a decimal. It is recommended that you choose a speed that can be divisible by 60, such as 300 RPM, 240 RPM, and so on. The relationship between the segmentation and the step Angle is that the larger the segmentation, the smaller the step Angle and the accuracy. But at the same speed, the pulse frequency is larger than the smaller segment
Q:The principle of permanent magnet step motor
Just checked, the machine of the miniature printer USES 25 series of electric motor is permanent magnet, step in Angle 15 degrees. Apart, it's very rough. I used to focus on application and control, but I didn't notice. The 35 series that we use seem to be permanent magnet, too. The 42 series and the 58 series are mixed, and the two have been split several times. It seems that you want to design step motors. If I had to go that far, I wouldn't have figured it out. I'm just doing the application, and I'll show you a little bit more about how to control step motors. For your question, I suggest you look at the electrical engineering book, the electronic industry press. You're talking about eight magnetic claws in four phases, at least one pair per phase. The number of small teeth of a magnetic claw has to do with the step Angle. It seems that there is (at least some books in some books). Four phase eight beats is one way to run. This eight beats do not affect the design of the motor. In addition, based on my knowledge of the printer, most of the printer USES a hybrid step motor. The 42 series of motors that I use on this side are hybrid. It is as if permanent magnet motor, the step Angle is larger, not suitable for controlling the more delicate machine. I hope I can help you.
Q:The step motor is moving at the fastest rate of frequency
The speed of the data is said to guarantee the speed at which the torque is rated. You're going to increase the frequency and you're going to increase the speed, but you're going to have a lower capacity of the load. The basic goal of stepping motor is not to make it idle, or to carry a load. It doesn't carry the load even if you have that high speed.
Q:The maximum surface temperature of the step motor is permissible
Control the stepping motor in reasonable range The degree to which the electric motor can be heated depends on the internal insulation level of the motor. Internal insulation can be damaged at high temperature (130 degrees). So as long as the internal is not more than 130 degrees, the motor will not be damaged, and the surface temperature will be below 90 degrees. As a result, the surface temperature of the stepping motor is normal at 70-80 degrees. A simple temperature measuring method is useful for a thermometer, and it is also a rough judgement: you can touch one to two seconds with your hand, not exceeding 60 degrees. You can only touch it with your hands, it's about 70 to 80 degrees. A few drops of water quickly vaporize, and more than 90 degrees; You can also use a temperature gun
Q:Why do you go into the motor and you don't have to do it again
You see if the line is connected, I've seen this before, because it's not connected. Can you feel the motor vibrate with your hand? If you can! It could be that your drive pulse is too fast, and it's a step into the motor. Good luck to you!
Q:What is the difference between a step-down motor and a dc reducer
Dc motor speed is high, sometimes can reach hundreds to thousands of revolutions per minute, the speed for real-time control systems put forward high request, if control system failed to keep pace with, that will cause out of control. After the reduction gear, motor speed decreases significantly, sometimes can be dropped to 36-200 RPM, using single chip microcomputer control motor operation is relatively easy. A simple example, if you do the smart car, with general dc motor, to control the motor running, turning, obstacle avoidance will be quite difficult, it is easy to run partial, but if you use dc motor control is quite easy.
Q:Is the stepping motor fast?
Look at your conditions of use, if it is 1000 RPM, stepper motor you can have a try, it is commonly used at low speed, with the speed increase, the output torque is becoming more and more small, on the 1500 r is almost no power, can say to 2000 turn above is not practical. Its main feature is low speed, rapid stop, positive and reverse, position control.
Q:PLC control step motor problem
So if you try, 1/16, 8000HZ try it out! What about the effect? It should be 150 revolutions per second; And then you know, if you go to 14, 8000HZ, you know what's the problem with the pulse here or the problem with the motor here! What I'm talking about is not the location problem, the PLC's high speed pulse output is not as accurate as it says, and the balance is normal!
Q:The step motor allows the group to be electrically locked.
Not only sending back to keep the original bearing motor winding, only after the analog signal to the motor, the motor will rotate, rotating ring according to the signal number, to complete in an axial movement, pure to electricity, will lock the motor position, because the signal source is 4 ma.
