Transient performance simulation of permanent magnet motor

In this paper an original approach to modelling and transient simulation of an electronically operated permanent magnet motor (EOM) is presented, with special attention to determination of its dynamic and transient characteristics, which are analyzed. This type of motor appertains to the generation of new special motors, supplied and controlled by modern semiconductor devices. The mathematical modelling of the EOM presented in this paper is performed by the corresponding dynamic model of the motor itself and by a proper modelling and simulation of its control device. A particular mathematical model for calculations of dynamic characteristics of the motor is derived and presented, too. The dynamic characteristics of torque, current and speed, for different control parameters is also presented on diagrams. The transient simulation of the electronically operated permanent magnet motor is carried out by using these characteristics. The proposed methodology is used for an extended analysis of dynamic performance of an EOM and prediction of its transient behaviour is also performed
