BMW 3: Connections

Connections, electrical machine
- Transmission bell housing
- Temperature sensor
- Coolant ducts
- Connection for coolant (transmission oil)
- Electrical connection, rotor position sensor
- High-voltage connection
There are four connections of the electrical machine on the housing of the
automatic transmission for
the following components:
- Temperature sensor
- Cooling (by transmission oil)
- Rotor position sensor
- High-voltage cables
High-voltage connection

High-voltage connection, electrical machine
- High-voltage connection
- High-voltage connector
Electrical energy is fed to the coils of the electrical machine via the
high-voltage connection. The high-
voltage connection connects the Electrical Machine Electronics to the electrical
machine via a three-
phase, shielded high-voltage cable.
The high-voltage connectors are screwed on to the Electrical Machine Electronics
and the electrical
machine.

High-voltage cables must not be repaired. In the event of damage, the
line must always be replaced!

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.
To guarantee the thermal operating safety of the electrical machine in every
situation, it is cooled with
coolant in the G20 PHEV. For this, the electrical machine is integrated in the
coolant
