I am trying to rotate this type of motor http://rs-catalog.ru/index.php?dispatch=products.view&product_id=41472 and here you can find it’s datasheet http://docs-europe.electrocomponents.com/webdocs/0739/0900766b807394bd.pdf. I am using the L298 as an H-bridge for this motor but the motor did not rotate and I am afraid that something from the H-bridge is happening i am connecting like this http://www.google.com.mt/imgres?q=L298+Dual+H-Bridge+Motor+Driver+schematic&hl=mt&sa=X&tbm=isch&prmd=imvns&tbnid=TrOGmk2ELueqSM:&imgrefurl=http://www.solarbotics.com/product/k_cmd/&docid=Di5xbW41e59r6M&imgurl=http://content.solarbotics.com/products/schematics/solarbotics-l298_schematic_complete.jpg&w=1056&h=760&ei=igqcT5yGBcfsOc6nyPsB&zoom=1&iact=hc&vpx=186&vpy=257&dur=3&hovh=190&hovw=265&tx=145&ty=118&sig=101803358702399884465&page=3&tbnh=142&tbnw=197&start=42&ndsp=24&ved=1t:429,r:12,s:42,i:182&biw=1366&bih=667
but instead I didn’t make the voltage regulator because no use of it i am expecting because the +5V is getting from the Enable from the micro. And another thing that I changed are the diodes instead i used 1N5822 , becuse between each phase there are 2A can some one help me and tell me what is the cause that the motor didn’t rotate thanks alot
using a l293d for driving a stepper is very complex i preffer you to use
ULN2003
this is a darlington array
to drive a stepper first you need to understand the type of motor and working of it
follow the link

Thanks for helping me but I can’t use this IC becase I need 2A as an output current and this IC can only drive an output current of 500mA what can I do
I you better use darlington pair TIP 100 or TIP 102 for each pin of the motor. In datasheet the maximum collector current is given as 8A.

yes
in that case i too prefer to go for high current MOSFETS for better switching
but they are a bit costly
i used a tecnique
i took three 2003 ics and
short 4 inputs and and short the coressponding out puts
as a result you will get 500*4=2000mA=2A
the cost will be less compares to that off MOSFETs as the need proper biasing circuit

Can someone tell how the stepper motor works do I need pwm for the stepper motor to rotate
Can someone gives me a good program for the hybrid motor thanks alot
There is an article about the stepper motor in engineersgarrage. Please find the link
