#82571 - Most Accurate Control Responding to: ???'s previous message |
Certainly the most accurate way to control the motor speed is to install an encoder wheel or a tachometer and measure the resulting signal and build a feedback control in the software that can regulate the PWM signal with which you would drive the motor.
A very simple tachometer could be made with either an optical interrupter reading a slotted disk that is mounted on the motor shaft. Another possible scheme is to use a brushed motor and tap into the brush circuit to read out the motor speed. Michael Karas |
