Vibrations and noises occur during the operation of synchronous motors. To reduce them, more advanced engine designs and special control algorithms are used. The application of a multiphase (m > 3) synchronous motor design allows you to influence the configuration of the magnetic field in a wider range. Thus, the task to develop a control algorithm that improves the vibration-noise characteristics of a multiphase motor is relevant. The finite element method is used to calculate the magnetic field in a 2D formulation, implemented in the Elcut software package. Also, the simulation methods with the MatLab Simulink package are applied. The authors suggest the algorithm to control multiphase synchronous motors with permanent magnets that reduces the level of vibrations. Improvement of vibration-noise characteristics is achieved when the motor is supplied with currents of the certain form, and they compensate the pulsation of electromagnetic forces that occur between various parts of the electric machine. This algorithm is based on the measurement of the electromagnetic forces and the torque directly in the process of control. The results of modeling the operation of the engine with the developed control algorithm are presented. The authors have compared the characteristics obtained using the developed control algorithm and the characteristics that correspond to the sinusoidal source supply. The vibration-noise characteristics of a permanent magnet synchronous motor can be improved by using the control system. This control system generates currents in an appropriately synthesized form. In this case, the power consumption will increase slightly.
