Good morning everyone, I've been studying stepper motor functioning in order to choose the right one for my application with proper control board. Before buying I wanted to ask your opinion just to make sure I'm buying the right things. I need a motor capable of exerting a 20 Nm torque when spinning at 10 RPM or lower. I've choosen the follow
Hai, I have a doubt about EDE1400 IC. I read data sheet of this ic. I have attached the schematic of this IC with micro controller. by doubt is there is no connection to stepper motor. how we control the stepper motor? or no need of that? And from where i could by this IC? Please give me a reply for this. (...)
Hi guys.. I am at the moment trying to make a stepper motor move, but can't seem to make it happen. I am interfacing it through a control board, which takes the input Step, Dir, En, and 5V. I am providing those inputs signal from an arduino, but can't get the damn thing to move. all it does it move a step forward and backwards, like it
Microprocessor PWM units are not well suited to drive stepper motors. Instead use timer interrupts and pulse pattern generation in software.
Hi, I am using dspic30f5011 controller and I can generate PWM wave by using output capture compare module.Now,I want to control the 4-wire bipolar stepper motor with PWM i.e, rotation speed.So,what driver I have to use? Thanks and Regards, M SAI KIRAN.
so i think i need keep on read current through shunt res ? and need to control through PWM right? That's the usual way to operate stepper motor with constant current. Unipolar motors like yours are more often operated with constant voltage, yours is obviously designed for a lower voltage than 12V. In any case you should get an i
Hi all, Recently I am learning on how to control a stepper motor. The circuit working condition is as below: PIC 16F628a --> ULN 2003 --> 28BYJ-48 stepper My code is as below: void main() { CMCON = 0x07; // To turn off comparators TRISB = 0; // PORT B as output port PORTB = 0x0F; do { PORTB = 0b00000011;
The following video shows a remote controlled bipolar cd-rom stepper motor. The remote control used is a TV remote control uses RC5
First of all hello there, this is my first thread. So I started working on a mini cnc machine made from old CD drives. I plan to use the mechanisms to build a plotter like structure. When I tore them down I was expecting a stepper motor at the beginning of the lead screw, but what I got was a standard dc motor with no encoders or any means for a
can we control stepper by using tb6600 by using the below flow code? the tb6600 board i am using have EN ;CLK ;DIR pins and M1 M2 M3 and TQ for (i=0; i<=10; i++) { EN =1; CLK =1; DIR =1 CLK =0; EN =0; EN =1; CLK =1; DIR =0; CLK =0; EN =0; }
hello dear forum , I have designed an OEM PLC board which can connect to DELTA DOP touch screen operator panel - for small machine control moreover this board can count external incremental encoder signals and also can drive a stepper motor who interested in automation please look at below demo video ( 3 min only ) showing about all t
L6474 is designed to perform individual steps triggered by a digital input. All operation parameters are set through SPI. If you need only slow stepper motor operation, you can perform steps by writing to the electrical position register without using GPIO pins.
I wanted to control a stepper motor of high torque by a push button,such that whenever the push button is pressed it moves one step ( say 5 degree) how to go for this? I have a 24 dc supply thanks in advance
This is a brochure not a datasheet, there are no electric specs in it for the stepper motor. And it describes more than one expansion valve type. The lessest you should do is to tell the exact type number of your valve.
Hello Sir.. I am Using L297 and L298 stepper Drive with Bi-polar stepper Drive. I just gave the 1 to the direction pin but the motor changes its direction unconditionally. Some time it goes clockwise direction and sometime it goes anticlockwise direction. I just feeling helpless nothing comes in my mind. :( I check the circuit many times it
Hi, i am working on a project which requires me to control a valve using a stepper motor. I need guidance on how to figure out the size of the stepper motor that will be able to open and close the valve comfortably, such that the torque shouldn't be too low neither too high, we don't want to leave the valve un-opened and neither do we want (...)
Without specs or details on implementation, I assume Relay provides for slow adjustments with tap change and lifetime limit on current load switches is unknown. This is common for some high power (MVA) distribution or feeder transformers to have active load switch taps with relay control. Servo implies stepper motor controlled variac (...)
Hi, I can't see how you want a stepper motor to move. You just control two outputs: pc0 and pc3. If one channel is higher, them pc0 is ON and pc3 is OFF. When the other is higher, the, pc0 is OFF and pc3 is ON. If both are the same, then it repeats the previous state. But with this you can't control a stepper. Read on how (...)
Hello, I am using Nanotec ST6018L3008-A stepper motor in my positioning applicaitons with 24V 2.12A in serial winding configuration. But esspecially in middle speeds like where torque starts to reduce, system vibrates alot. I am thinking about use my stepper motor in 24v 4.2A in parallel windig configuration. I think that paralel winding wil
Hello~ We were given an assignment in class where we have to design an fsmd to control a stepper motor, draw the asm charts, hardware architecture, write the code in System Verilog along with test-benches and lastly, simulate it. The task is divided into 3 parts, where the 1st one involves moving a stepper motor 10mm right (it follows a (...)

hi , i have to move two stepper motors simultaneously in XY plane. i am using pic microcontroller 16f877a. kindly tell me the algorithm to implement this
Wait. YOU are asking US if you miswired your circuit? And how, exactly, would you expect us to determine that? But forgetting that for a moment, you need to control the average current to your motor windings. I think you need to learn something about driving stepper motors, PWM, feedback and such. Just using basic electronic theory: you've got
Some more clarification where the confusion lies: I have both unipolar and bipolar motors that were paired with these drivers/controllers posted (one set is coming from an older commercial printer and another from a commercial mail-sorting equipment) and wanted to reuse them. Maybe I am overthinking this but "clock" input
Hello, I am curious about something. Recently I bought a small bipolar stepper motor and a driver that supports microstepping. This driver has 4 outputs (2 outputs and 2 inputs actually) that can be directly connected to a bipolar stepper. It can also take digital input via simple IO pins - three of them are used to configure microstepping, one
Hi friends I want to know the way of control of PM DC stepper motor both direction (rotation) and step by step.
For my project, stepper motor will be used to rotate thermostat knob. My problem is i want stepper motor to rotate to the shut off position of knob. When the knob is not moving(obviously it has some shutdown point), stepper motor should stop rotating. Is there any mechanism for microcontroller to know that (...)
Your stepper motor is working exactly as it's supposed, it moves in steps! If you want it to run faster, you'll have to give it a faster step rate. I'm not sure why you are comparing a step motor to a speedometer, though; they are two entirely different things. What are you using to control the stepper?

As chuckey said, stepper motors are best used with current source drivers. It doesn't need to be complex, you just need a peak current mode control loop on each half bridge.
Yes but you need a stepper motor driver/controller. Refer the following link for such
I'm using stepper motor driver DRV8811.. I getting output from Aout_1 and Aout_2. There was no output from Bout_1 and Bout_2. It's same in all step mode. I little bit confused... What is the problem???
You will have to use Servo motor with gear box. stepper can't be used.
Hello friends. i was making a small basic project on proteus professional , a stepper motor control using 89c51. i made the schematic but i don't know why its not working. i am attaching the project file here. Thanks in advance.
It is quite common/useful to use PWM for speed control whether you are using a stepper motor or simple brushed DC motor with feedback or measuring motor emf. With many robot arm applications it is important to have the position or angle so most often a stepper (in which you know how many degrees per step) or a motor with encoder or (...)

Hello Barry, I am driving the motor in PWM mode. As you rightly pointed out, I am trying to generate detailed requirements for stepper motor operation such as current, optimum stepping angle etc. with which I can configure my motor driver for efficient operation. For determining micro stepping, I want to know how micro stepping and torque are
does the following code for stepper motor makes only single step clockwise rotation or 180 rotation and stop?i want to rotate at 1 degree in 1min.does the following code useful? clock() //function for clockwise rotation { P2=0X11; T0delay(56); P2=0X22; T0delay(56); P2=0X44; T0delay(56); P2=0X88; T0delay(56); } }

In a bipolar stepper driver, you can measure the current with low-side shunts. You may have noticed that stepper drivers are often operated in constant current mode. In this case, measuring shunts and a current control loop will be already present in the driver circuit.
