Stepper motor Definition and 63 Threads

Hello, Recently,I got 2 stepper motors,one which was dismantled from a blood analyzer machine and the other one was bought from a local store. The stepper motor spec from the machine is: 12V dc 1.8 degree resolution 1A The stepper motor spec bought from the store is: 12V dc 1.8...

I've got a 12V, 2 Ohm/winding rated motor and I'm trying to figure out how much current it'll take. From Ohm's law 12/2 = 6A - and that's a lot! Is this much current needed to drive the motor? Can I use a lower amount of current? If so, how do I limit it? I don't have the datasheet for the...

Hi, Can any expert advice if I can control the DC motor to make it work as a stepper motor? I am using PLC to control the DC motor clockwise and counterclockwise in steps. Output O:1/0 controlling clockwise and O:1/1 controlling counterclocewise.I will use the timer say 0.5s pulse to...

I'm making a circuit around the stepper motor controller L297 on a breadboard, and I've got it working so far. I haven't connected it to the H-bridge and so obviously not to the motor either. But I'm checking the logic levels using 4 LEDs connected to the outputs and they corrospond with the...

To the viewer of this post, I wish to create a device which can replicate a rotation at point A at point B. What I was thinking was using a stepper motor to replicate the rotation at point B through the use of a controller and have some sort of mechanical-to-digital device which could incode...

-------------------------------------------------------------------------------- Hi All I am using a ULN2064B to control 2 stepper motors, and the input to the IC is directly from an I/O port on an 8051 microcontroller. The stepper motors are 24V, and "apparently" need 800mA each to...

Hi I have a project I want to find a programme or write a programme in C language oe Visual Basic or any other appropriate computer language, can anybody help me to do that? Thanks

Homework Statement I am in such a situation, where we are trying to measure the characteristics of a stepping motor in order to verify its operational characteristics. I have tried measuring the motor's torque in many ways but I am having trouble following the company maker's method given...

Hey all I am trying to sort through data for controlling a unipolar stepper motor with a microcontroller. I have done this before but the hardware was already in place on a development board. What I need is a way to drive a 12V Unipolar stepper with a microcontroller. I have found a number...

Is there such a thing? i have had a search but found nothing, i can think of a way that one would work, but i need one that can (step) 90 degrees in 25 milli seconds and hold possition until the next step is called for. anyone that can help will be rewarded with one of my fantastic chili cakes.

Hi all, I want to use an analog joystick to control a stepper motor and also power a relay which powers a second circuit. When the joystick is pressed side to side I want the stepper motor to turn at a rate dependant upon the position of the joystick. If the joystick is pressed forward or...

I have a SI 7300A chip which is used to drive bi-polar stepper motor. Is there any circuit avaiable online, which i can use to drive my motor ??

Is anyone familiar with the Basic STAMP 2 microcontoller? I have found a little information about it, but not much. I would like to start tinkering around with some type of microcontroller, probably something to run stepper motors. Would this be a good choice? Specifically, I am thinking...
