Core Losses in DC Motor Formulas

Core losses are defined as the sum of hysteresis and eddy current losses that occur in the armature iron current due to a small induced current. And is denoted by P_core. Core Losses is usually measured using the Watt for Power. Note that the value of Core Losses is always negative.
