The master's thesis presents the influence of the geometry of the permanent magnet synchronous motor, which has a topology of permanent magnets in the shape of the letter V (IPM-V) on the area and position of maximum efficiency and its adjustment according to the desired shape of the efficiency map.
The first part describes the mathematical model of a synchronous motor with permanent magnets.
The second part presents models for calculating losses in copper, iron and permanent magnets. Special emphasis is placed on the methods used for iron loss calculations, their advantages and disadvantages, and their applicability.
The third and fourth part is focused on MTPA - Maximum Torque Per Ampere, FW - Field Weakening and MTPV - Maximum Torque Per Volt strategies for linear and non-linear models of permanent magnet motors, as well as control methods in the region of constant torque and constant power
In the following, the finite element method and the principles of calculating losses in iron using the finite element method are briefly described.
In the last part of the master's thesis, we presented the influence of the geometry of the stator and rotor of the permanent magnet synchronous motor (IPM-V) on the shape of the efficiency map.
