I am looking at running a routine when a motor starts to rotate and wondering if anyone can tell me the best method of going about this. As the motor is not in the equipment at the moment so cannot get accurate measurements from it but is the paperfeed motor in a epson printer and is a dc motor running on PWM. As i dont know what the maximum motor voltage is at the moment but can be took into consideration when designing the interface which would be the best approach to just test when the motor starts would i need something like a optic isolator or something more simple ?
