Wybrane parametry techniczno-konstrukcyjne silnika synchronicznego z magnesami trwałymi o sterowaniu trapezoidalnym

In the paper the calculations of technical-design parameters of a synchronous motor with permanent magnets in rotor, three-phase stator winding and with trapeze waveform control are given. The dependencies of self and mutual inductances, associated fluxes and electromagnetic moment on stator current are presented. The presented dependencies have been prepared with the used of developed models. The dependencies make it possible to analyze physical processes occurring inside the motor. Flux is a nonlinear vector function, whose values are calculated on the basis of magnetic field distribution determined with the use of specialized software. Analytical calculation of partial derivatives is endowed with certain problems and the necessity to carry out a large number of additional calculations. The simulations and calculations have been carried out for the motor IPMSg132 S4 BLDC. The results have been presented in the graphical form.
