Please help me to build a bipolar stepper motor control - Electronic Circuits Projects Diagrams Free

Hello everyone,
I have a stepper motor, build by Superior Electric’s; it’s a 2.3VDC, 2.7 AMPS, bipolar motor. I tried to drive that motor with many schematic's on web but the motor power is very less (if I touched the motor shaft with a finger, motor stops). I want to drive this motor both ways and want to block the motor for some time ones it move each way.

Can anybody help me to build a simple motor control?

It's not simple because it's bipolar, so you need two H-bridges to feed it. Are you sure on the voltage?, that seems exceptionally low?.

The high current requirement tends to render most IC H-bridges useless, as does the low voltage.

Yes, the voltage is correct. This motor has driven by L298 with L297 IC, and its a complicated circuit with many microprocessors. I’m using these motors for modifying a machine.

It need 2 hbridge and you say its complicated why giving hard time just say google it u might find a better forum that this one with more expert 1
THis forum is useless i am waiting for simple answer toooooooook these guy to send year writing something which a 12 year old guy can tell! How ashamed i am

I won't bother polish my english for such a useless forum!!!!!!!!

So you don't like it here.

I have some advice for you, STFU and GTFO.

Wow 3 sqaure red reputation.

What's the problem, has to be a million Google hits for bipolar stepper motor controller, even plenty with a 16F84. Lots of quad half bridges out there too.

Is that a record for this forum?

If he keeps this crap up his reputation will soon be as negative as Roff's is positive.
