| 1 | Engine control in the TCM |
| 2 | Stator coils |
| 3 | Rotor |
| 4 | Hall sensor |
The stator coils are actuated by the electronics in the TCM in such a way that a circumferential magnetic field is generated. The rotor runs behind the magnetic field. Via the Hall sensors, the TCM receives information on the position of the rotor and calculates by how many rotations the motor has been turned. This information is required by the TCM to actuate the shift forks in accordance with the specified torque angle and to actuate the clutches. A detailed description of the function of the brushless DC motor can be found in the e-Learning module "Sensors and Actuators" (TC 401 2071C).
