A two-dimensional analytical model of a brushless motor with permanent magnets is developed on the basis of the Fourier variable separation method. The general calculation area of this model includes ferromagnetic areas and permanent magnets with a real configuration. Permanent rotor magnets, stator winding currents, and induced magnetic inductions in the stator teeth are sources of the magnetic field. The calculated values of magnetic inductions in media are found with allowance for stator serration, winding harmonics of the magnetomotive force, and the geometric structure of the arrangement of permanent magnets. The calculated functional parameters of the motor (current, torque) obtained in the model are close to its passport values. [ABSTRACT FROM AUTHOR] |
