Abstract <p>To drive devices with an external rotating part, it is advisable to use inverter synchronous reactive magnetoelectric motors with an external rotating rotor and an internal stationary stator. Inverted motors with segment magnets, nonmagnetic barriers, and magnetically conductive teeth between the magnets in the external rotor with a small number of pole pairs demonstrate the maximum torque, operational stability, rational machine volume, dynamic and energy characteristics, positioning accuracy, and reliability of rotor magnet fastening. The influence of the additional reactive torque in inverted magnetoelectric motors caused by the presence of magnetically conductive teeth in the external rotor increases with a decrease in the number of poles. Transient electromechanical processes in such motors are smoothed out with a decrease in the number of poles. Magnetically conductive teeth in the external rotor of the motor lead to additional torque pulsations in the steady state and increased electromagnetic noise. Torque pulsations increase with a decrease in the number of poles. With the increase of magnetic properties of magnets and decrease of their thickness and height of magnetically conductive teeth, their influence in inverted magnetoelectric motors weakens. Application of damper winding with its placement between teeth and magnets in external rotor smooths transient electromechanical processes, reduces torque pulsations, increases the period of oscillations, and leads to additional electrical losses.</p>
