Generic model of an electric drive with constant efficiency:
- The throttle signal is limited in the range [-1..+1].
- From the limited throttle signal the torque demand is calculated by the field weakening block, taking into account actual speed.
- The torque demand goes through a PT1-block, representing the time constant of the current controlled drive.
- The resulting torque demand is applied to the inertia of the motor and the shaft.
- Based on the mechanical power, the losses are calculated by the drive efficiency block.
- Based on the mechanical power and the losses, the ideal power converter calculates the dc current,
taking actual dc voltage into account, based on a power balance.
Losses are dissipated either internally or to the optional heatport.
