M AN894. Motor Control Sensor Feedback Circuits A list of the sensors that can be used to Feedback Author: Jim Lepkowski information to a microcontroller are listed below: Microchip Technology Inc. Current sensors - Shunt resistor INTRODUCTION. - Current-sensing transformer Sensors are a critical component in a Motor Control - Hall effect current Sensor system. They are used to sense the current, position, Speed/position sensors speed and direction of the rotating Motor . Recent - Quadrature encoder advancements in Sensor technology have improved the accuracy and reliability of sensors, while reducing - Hall efect tachometer the cost.
voltage drop across a known low value resistor is monitored in order to determine the current flowing through the load. If the resistor is small in magnitude, the voltage drop will be small and the measurement will not have a major effect on the motor circuit. The power dissipation of the resistance makes current shunts
