AC motor current measurement This Feedback article is written by Jim Lepkowski from Microchip Technology Inc. Sensors in are used to sense the current, position, speed and direction of the rotating motor. In most systems, several sensors are used to provide feedback information on the motor. These sensors are used in the control loop and to improve the reliability by detecting fault conditions that may damage the motor.

The three most popular current sensors in applications are: Shunt resistors, Hall effect sensors, and Current transformers. Shunt resistors are popular current sensors because they provide an accurate measurement at a low cost. Hall effect current sensors are widely used because they provide a non-intrusive measurement and are available in a small IC package that combines the and signal-conditioning circuit. Current-sensing transformers are also a popular technology, especially in high-current or AC line-monitoring applications.
