Abstract
An electric machine for a vehicle, comprising a stator, and a rotor comprising a plurality of poles, where each pole comprises a first V-shaped flux barrier and a second V-shaped flux barrier, where the first V-shaped flux barrier comprises two magnets with inner air cavities and outer air cavities, where the second V-shaped flux barrier comprises two magnets with inner air cavities and outer air cavities, and where the first and second V-shaped flux barriers are arranged adjacent each other and symmetrically to a d-axis of the rotor, where each of the poles further comprise a first V-shaped flux redirector arranged symmetrically to the d-axis and between the first V-shaped flux barrier and the second V-shaped flux barrier.

An electric machine for a vehicle comprising:
- a stator, and
- a rotor comprising a plurality of poles,
- where each pole comprises a first V-shaped flux barrier and a second V-shaped flux barrier,
- where the first V-shaped flux barrier comprises two magnets with inner air cavities and outer air cavities,
- where the second V-shaped flux barrier comprises two magnets with inner air cavities and outer air cavities, and
- where the first and second V-shaped flux barriers are arranged adjacent each other and symmetrically to a d-axis of the rotor, and
- where each pole further comprises a first V-shaped flux redirector arranged symmetrically to the d-axis and between the first V-shaped flux barrier and the second V-shaped flux barrier.
The electric machine of claim, wherein the rotor is provided with an air void arranged at an inner part of the rotor and between two adjacent poles.
