3. Energy optimization of gear teeth and MRV structures

The main electrical performances of MRVs are determined according to the general principles presented in paragraphs 1.3 and 1.4 of article .

In what follows, we will examine in turn :

  • the influence of tooth geometry on torque ;

  • the problem of choosing excitation fmm ;

  • the types of macroscopic structures likely to offer the best performance in terms of mass torque.

3.1 Gear geometry characteristics

The main problem is torque optimization. For a machine of given dimensions, we look for the geometrical dimensions of the rotor (for a machine with a smooth stator) or the dimensions of the rotor...
