l293 bipolar motor driver

Pls, Help me
I want to controll Motor Bipolar Stepper 5A with L293.
L293 peak Current only 1 A but Motor Stepper needed 5A
Can some body help me, pls

four motor bipolar stepper

Try some discrete mosfet design, L293 is not suitable for this job

l293 bipolar stepper

I try with with MOSFET IRFZ44 and MTP2955.
But MTP2955, I cann't find it.
Pls help me

Pls help me

This circuit isn't good because of the drains of top MOSFET is connected to high voltage. I suggest to you another good H-bridge **broken link removed** If you motor's power supply more than 20V add zener to drains of top MOSFET to protect them. You can use any zener at voltage 15 V.

l293 bipolar circuit

Dear haker_fox,
in my project: bipolar motor stepper have 4 wire

89c51 circuit to bipolar stepper

You have to use 2 of them (one for each coil)

Dear haker_fox,
in my project: bipolar motor stepper have 4 wire

Well, you have to use two of them as in your first circuit.
Good luck!

But I have problem, How to get position of stepper?
I use controller 89S51,
Please help me
thank's

I think that crasstalk is unuseful here. You have answered your question in another topic.

l293e stepper circuit

dear haker_fox
If i use encoder and stepper, i think's bad idea.
but if i use motor and encoder, it's good idea

Re: l293,

can u explain how this circuit works
**broken link removed**
My Bipolar stepper motor is of rating
Rated Current 6A
Rated Voltage 4.8v
Step angle 1.8
Number of phase 2
Holding torque 22Nm
Weight 8.6Kg
Iam using a Gear Box of ratio 1:20
So at the output iam getting a final torque 44Nm
i want lift a barrier arm of 3m length and around 10 Kg weight
will this circuit be applicable for my project
