BMW 3: Design

The main components of the electrical machine are:

  • Rotor and stator
  • Connections
  • Rotor position sensor
  • Cooling

The hybrid system in the G20 PHEV is a so-called parallel hybrid system. Both the combustion engine and the electrical machine are mechanically coupled with the sprockets. For vehicle drive it is possible to use both drive systems individually and at the same time.
