stepper motor problem

[cool]

hii.

i have interfaced a stepper motor with my microcontroller

 

the stepper motor has a voltage rating of 24 volts

i have used ic l293d as a stepper motor driver to control my stepper motor.

i am using wave drive mode(single phase) to rotate my motor ..because full drive causes the l293d to over heat..

 

though the motor rotates perfectly as programmed

 

but

1) it stops to rotates under slightest load.

 2) l293d heats too much 

 

plz guide me how i can increase the power of my stepper motor…

can you send me the diagram of this So that i can tell you what is the problem you have.As per you statements You are feeding the 5volt to the L293D input.But you gave the 24 volts as a reference .That is what the problem i think so.Try to upload the diagram with ratings
