Shunt current measurement

Webcurrents can be measured by means of low-cost shunt resistors with a simple interface between the shunt resistors and MCU inputs. The phase current is measurable only at a certain instant and thus the current sensing based on the shunt resistors requires support from the MCU. Freescale dedicated motor control devices provide exceptional WebIn this sense, a precision shunt resistor “converts” a current value into a proportional voltage value. Thus, current may be accurately measured by measuring voltage dropped across the shunt: Current measurement using a shunt resistor and voltmeter is particularly well-suited for applications involving particularly large magnitudes of current.
