Abstract
The structure of a brushless magnetoelectric torque motor with a slotless stator with a surface installation of permanent magnets on the rotor is considered. A motor model has been developed to calculate its characteristics in the COMSOL Multiphysics 6.0 software environment. The optimization of its structure was carried out, as a result of which the opti-mal number of pole pairs and such a ratio between the dimensions of the elements of the electromagnetic core of the motor were determined, at which the maximum electromagnetic torque per unit of power consumption is achieved. The paper also touches upon the problem of achieving the minimum value of the torque ripple factor in motors of a similar design. Ways of its solution are proposed both due to constructive changes in the magnetic system, and due to the syn-thesis of reference signals for the formation of such forms of currents in the stator phases, as a result of the interaction of which with the rotating magnetic field of the rotor, the motor torque characteristic the with a minimum value of the ripple factor can be obtained.
