- E-drive (Example)
This simplified E-Drive system is composed of an electric machine, its controller and its power electronics. From the user perspective, the system is primarily responsible for the acceleration of the vehicle. From the architecture perspective, the system is responsible for controlling the torque that is applied by the power electronics.

The system is also composed by the rotor position sensor, which measures the angle of the rotor of the e-machine, the phase current sensor, which measures the phase current values of the three phases that flow through the motor and a torque controller that calculates the torque and sets the PWM. This last value is calculated out of: the measured phase current values, the angle of the rotor and the torque reference-value. This last one is set by the acceleration pedal sensor, according to the drivers desires. Finally, The PWM is applied to the power stage driver, which adjusts the current for the e-machine and therefore sets the desired torque. The e-machine converts in this way the electrical energy into mechanical energy. In the modeled example you will find further components, which have been integrated in the architecture as part of the safety measures. Primarily to avoid an undesired vehicle acceleration.
