The authors introduce a new method for simulating phase-controlled induction motors. This method consists of utilizing the general model of the motor, referred to the equivalent two-phase machine, and of applying suitable input signals when the current is switched-off in one or more windings.

In electrical drives using an actuator supplied by a static converter, it is possible to work out a model of the converter-motor system which is easily implemented on a hybrid or digital computer. This model can be elaborated to improve the efficiency of the digital simulation. Computation time...
