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
Hi I have STM32F1 series MCU to integrate with L6474 stepper IC driver. But I found it from the manual that L6474 have API command to integrate with MCU using SPI. But from the manual of L6474, I have found them using both GPIO and SPI together. So my question is if I use SPI to communicate with MCU ,why should I concern about GPIO inte
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 (...)
