#125836 - Speed control of a pump Responding to: ???'s previous message |

Yes Ian, all I need to do is control speed of motor very accurately. Thats why I said in the start that I am not trying to do anything fancy with it. Any suggestions, recommendations for hands on training. No training recommendations I am afraid but from what you have said so far it seems to me a small dc motor would be a far more straightforward solution. A very simple encoder feeding a single chip 8051 interrupt and a very simple PWM motor drive (assuming you do not need to reverse) are all you need. An rs232 link could be used to input speed commands and possibly return status. Worth developing if you need a few hundred such pump controllers. I have developed many such dc motor controllers in the past and they work very well. The dc motor has much better torque/speed characteristics than a stepper for this type of application. Just my twopeenyworth. Ian |
