Torque prediction using the flux-MMF diagram in AC, DC, and reluctance motors [PDF]

, 1996
This paper uses the flux-MMF diagram to compare and contrast the torque production mechanism in seven common types of electric motor. The flux-MMF diagram is a generalized version of the flux-linkage versus current (ψ-i) diagram for switched-reluctance ...
