This work aims to enhance the operational capacity of electric drives by addressing voltage and performance constraints.
Developed an electromechanical architecture with an auxiliary motor-generator path.
Implemented a mode-scheduled control strategy to activate assist power as needed.
Conducted analytical assessments and time-domain simulations to evaluate performance enhancement.
The architecture expands the torque-speed envelope of electric drives.
Delays severe flux-weakening onset during operation.
Preserves high-speed performance without unnecessary losses.
