During the design process designers compute operation points such as maximum torque per ampere or flux weakening characteristics that cannot be targeted directly on the FEM tool. Therefore, designers make a sweep of simulations and post-processed the data in order to obtain the results, this is repetitive particularly in the conceptual phase of the design where features of the motor are still not defined. This paper presents nine algorithms as an alternative to compute with iterative methods operation points that cannot be targeted directly on a FEM tool. The algorithms must be coupled to the FEM tool and can compute complex points such as the characteristic current and modes of operations limits within acceptable range of error and times of execution for practical purposes. Validation of the algorithms using Jython is presented with results for the three types of brushless motors (non-salient, interior permanent magnet and reluctance motor). 1996-1073 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=147798 https://hdl.handle.net/20.500.11984/1100 AC grids analytical modeling design approach harmonic mitigation active impedance power system stability Field Weakening Characteristics Computed with FEM-Coupled Algorithms for Brushless AC Motors
