|Abstract:||A wide-speed-range electric drive is a system composed of a static converter and an electric motor that produce high torque at low speed and low torque at high speed, as in the case of a traction application. The performance is strongly influenced by the apparent power of the inverter, the impedances of the machine and the control law. The design methods that separate the design of the machine, the static converter and the control law do not always find an adequate solution. It is so necessary to carry a global optimization of the whole system. When optimizing the number of iterations is very important and the computation time is an important factor. This work presents analytic modeling methods suited for the optimization of drive systems. The methods are based in an equivalent circuit machine model and operating constraint model of the static converter. The methods rapidly calculate the currents, voltages, losses, torque, control law and performances of the different operating points of the system design specification. Those models are illustrated with traction system design examples and a car alternator design example. This work also presents an analysis of polyphase machines in fault modes.|
