hi im using an h bridge L293NE to drive a motor,the purpose is to drive the motor in two directions at a known frequency, my configuration is working however the motor doesnt spin fast enough. Do i need more current through the motor? if so how can i accomplish this??? Thanks! |

If you are driving the motor through PCM, it may be just the duty cycle at too short of a duration. Most H bridges are either on or off and don't really work all that well at anything but DC levels. If you want to regulate speed, it might be better to drive a stepper motor. It is almost as easy and requires just a little added circuitry. |
