What is a SHUNT? (Used to measure Current) - YouTube

WebShunt motors self-regulate (when driven by constant voltage). If the load drops, speed increases => back EMF increases => current lowers => torque lowers => speed no longer increases. Current through each motor in the string is the same, so one affects the other. WebAug 1, 2024 · With this technique, a known resistor R shunt is placed in series with the load and the voltage developed across the resistor is measured to determine the load current. This is illustrated in Figure 1. Figure 1 . Current sense resistors, also called shunt resistors or simply shunts, usually have values in the range of milliohms.
