Abstract
Space-phasors are complex variables based on the sinusoidal distribution of flux and current in the air gap of three-phase machines. They have many advantages for the understanding of physical processes during transients in a machine. The basic equations of the dynamic behaviour of an induction motor in space-phasor notation are derived and the special aspects of their application to synchronous machines are mentioned. For a current fed machine a transfer function is found and control procedures are discussed. Examples of diagrams in the complex plane demonstrate that space-phasors are a powerful tool in understanding the physical background and useful in finding an optimal control with inverter fed machines.Keywords
