The authors describe a universal method for composing a simulation model for any type of electrical rotating machine. Models for asynchronous machines, permanent magnet or excited synchronous machines, brushless and brush DC, stepping and variable reluctance motors are presented. A simulation model is needed when detailed interactions between driver circuitry, machine, load and controller are to be studied. In such cases it is usually not possible to transform the system into a solvable matrix differential equation. A general applicable transient machine model, interacting easily with existing models of its surroundings, the inverter and the mechanical load, is to be preferred.
