BMW 3: Rotor and stator

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.

     Separation clutch

    The G20 PHEV is a Full-Hybrid Generation 4.0 vehicle. In contrast to generation 2 and 3 hybrid vehicles, electrical driving is possible in the G20 PHEV at much higher speeds and with a higher range.


     Buckling the safety belt

    1. Guide the safety belt slowly over shoulder and hip to put it on. 2. Insert the tongue plate into the safety belt buckle. The safety belt buckle must engage audibly. When the safety belt is fastened, the driver's and passenger's belt straps are automatically tightened once after driving away. Un

     System components

    The front radar sensor (FRS) or the front radar sensor long range (FRSF) is needed to reliably detect the vehicles in front. Consequently, adaptive recuperation is only possible with the optional equipment Active Cruise Control with Stop&Go function (SA 5DF). Adaptive recuperation can be
