BMW 3: Rotor and stator

Design
Rotor and stator, electrical machine

  1. Stator
  2. Permanent magnets
  3. Rotor
  4. Hollow shaft with outer basket of separation clutch

The electrical machine in the G20 PHEV is structured as an inner rotor. "Inner rotor" means that the rotor is arranged with the permanent magnets arranged in a ring shape on the inside. The coils for generating the rotating field are located on the outside and form the stator. The electrical machine has 8 pole pairs.

The rotor is mounted above a flange on the rotor hollow shaft, which is positively connected to the transmission input shaft.
