The aim of the course:
Introduce the key components of electric drive systems, show how to select an electrical drive based on the torque speed requirements of the driven load for a range of applications, show how modern power electronics can be used for machine speed and torque control, identify control strategies for improving the energy efficiency and controllability of driven systems and enabling kinetic or potential energy recovery.
