If E and V are generated (or induced) and terminal voltages, IL, Ia, and If are line, armature and field currents and Ra is armature resistance, then the voltage and current equations of shunt generator and shunt motor are
1
V = E - IaRa; IL = Ia - If and V = E + IaRa; IL = Ia + If respectively
2
V = E + IaRa; IL = Ia - If and V = E - IaRa; IL = Ia + If respectively
3
V = E - IaRa; IL = Ia + If and V = E + IaRa; IL = Ia - If respectively
4
V = E + IaRa; IL = Ia + If and V = E - IaRa; IL = Ia - If respectively
