2. Industrial testing and calculation of operating characteristics

2.1 Measurements and characteristics at steady state

In steady state, the equivalent electrical diagram of the electromechanical system of a permanent magnet motor shown in figure 19 b can be reduced to that shown in figure 20 , all the elements of which can be deduced from two series of measurements at nominal voltage:

  • one unloaded (R ch ≈ ∞; I ch ≈ 0) which...
