Cornell is tough. Even tougher for engineering students. There will be days you feel like your the stupidest kid in the program, and you'll wonder if you belong with everyone else. But then you remember that your experience at Cornell shouldn't be shaped by your performance relative to everyone else. Rather, your experience there should be shaped by how much you've saturated yourself in the learning environment. There is no better place to expose yourself to all sorts of knowledge than Cornell.
Back-EMF Motion Feedback. INTRODUCTION. Electromotive force (EMF) refers to the voltage generated by a spinning motor. Measuring this voltage in order to determine the rotational speed of a motor is commonly called Back-EMF since the voltage tends to push-back against the circuit driving current into a motor's windings.
The MAF sensor is an electronic sensor that sends a signal to the engine computer, which then uses the measurements to help calculate fuel delivery and spark timing. In most applications, the MAF sensor utilizes an electrically charged wire to determine the amount of airflow entering the air intake.This wire produces an electrical voltage, based on airflow, and sends it to the engine computer, which then uses the information to adjust spark timing, fuel delivery and spark advance.n most applications, the MAF sensor utilizes an electrically charged wire to determine the amount of airflow entering the air intake.
