For synchronous machines, Langsdorf distinguishes between cylindrical rotor (high-speed turbines) and salient pole (low-speed hydro) designs.

Langsdorf introduces the two-reaction concept, decomposing armature current into direct-axis (( I_d )) and quadrature-axis (( I_q )) components, each with different reactances ( X_d ) and ( X_q ). The power angle characteristic becomes: [ P = \frac3 V_t E_fX_d \sin \delta + \frac3 V_t^22 \left( \frac1X_q - \frac1X_d \right) \sin 2\delta ] The second term (reluctance torque) is a distinctive contribution of Langsdorf’s analytical approach.
