Abstract
A rotor module for a rotor of a rotary electric machine with an axis of rotation having a stator and a stator core including radially oriented stator teeth is disclosed. The rotor module has a rotor module core and permanent magnets defining a number of magnetic pole pairs, including a first pole and a second pole. The first and second poles of each magnetic pole pair are adjacent. The permanent magnets define first magnet arrangements defining each first pole and second magnet arrangements defining each second pole. A first angle between the first and second pole of each pair is equal to 360° divided by two times the number of magnetic pole pairs. A second angle between a second pole of a first pole pair and a first pole of a second pole pair is the sum of the first angle and a first shift angle.
