I need to control 4 stepper motor from Arduino Mega. The motor I'm using PM14-M201. Torque produced with L293DNE, on giving 12 V from battery is insufficient. On giving 24V, L293DNE burns out even though it can support 36V.
Please help. Thanks in advance!
What should I do? Should I use some other IC or is there a way by changing the connections ?
A quick search reveals the 14PM-M201, not a PM14-M201.... Is that what you mean?
Its a 9 ohm 0.4A motor, designed for chopper driver, not really from H-bridges, since
the DC voltage would be 3.6V in that mode and the top speed sluggish.
A4988 chopper driver will handle 0.4A nicely, and then you can unleash 24V or more to
spin it quick.
