BMW 3: Connections

Design
Connections, electrical machine

  1. Transmission bell housing
  2. Temperature sensor
  3. Coolant ducts
  4. Connection for coolant (transmission oil)
  5. Electrical connection, rotor position sensor
  6. 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

Design
High-voltage connection, electrical machine

  1. High-voltage connection
  2. 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!
