What is MMF method?

MMF Method is also known as Ampere Turn Method. The synchronous impedance method is based on the concept of replacing the effect of armature reaction with an imaginary reactance, the Magnetomotive force (MMF).

Why is MMF optimistic?

The value of voltage regulation obtained by EMF method is always more than the actual value, therefore it is called Pessimistic method. 5. Why MMF method is called Optimistic method? The value of voltage regulation obtained by MMF method is less than the actual value, therefore it is called Optimistic method.

How to Calculate Full Load Field MMF?

Full Load Field MMF calculator uses Full Load Field MMF = Field Current*Turns per Coil to calculate the Full Load Field MMF, Full load field MMF is due to field ampere-turns (i.e., the product of field current and number of turns in field winding).The magnetomotive force (MMF) produced by the three-phase armature current of a synchronous machine is generally defined as armature-reaction MMF. Full Load Field MMF is denoted by MMF_f symbol.
