There is another design method for reducing tooth harmonic ripple: closed slots. The disadvantages of this method are large leakage fluxes, reduced EMF and increased inductive resistance of the armature winding, and the technological complexity of winding installation. However, these shortcomings are compensated by an increase in excitation MMF and the use of removable tooth: doi:10.1088/1742-6596/1559/1/012146.

 -140 how is the mechanical torque for a feedback loop measured? The mandatory presence of an additional torque sensor imposes significant restrictions on the areas of practical application of this method.

 The example shows a high-torque, low-speed electric motor. Is this a consequence of restrictions on the maximum rotation speed due to the insufficient speed of the calculation and control system, or the low sensitivity of the torque sensor?

 In Table 1 it is necessary to indicate the type of connection of the armature windings in star or triangle. The presence of the 3rd harmonic in figure 5 contradicts statement -114.

 The fonts on the graphs in Figure 4 are small. In the electronic version you can zoom in, but when printed, they are unreadable.

 It is possible that the non-traditional values on the horizontal axis of the graphs in Figure 5 are shifted. They start with the zero harmonic, there are even ones. Before the FFT result, it is advisable to show the original periodic function and its period. And indicate the number of armature tooth per pole division.
