Electric Drives

Electric drives comprise electric machines (i.e. motors/generators) together with power electronic actuation to enable the control of mechanical motion. Topics include electro-mechanical mechanisms for torque production relevant to rotating machines, speed-torque diagrams, DC machine analysis, dynamics and torque/speed/position control, introduction to space vectors and their application to motion control of synchronous machines and stepper motors. Steady state and variable speed operation of the induction machine using constant flux control is also covered.
