This paper deals with mathematical model of electrically commutated motor (BLDC) made up of standard components in the MATLAB/Simulink c environment and its toolbox SimPowerSystems c . The model is intended to create and verify of control algorithms for sensor and sensor-less operation of BLDC motor. It is possible to insert it to any complex control system as a functional block. The simulated motor is described by approximately 15 electrical and mechanical parameters that enable modelling a particular type of BLDC motor as faithful as possible. Insertion of parameters and post processing are realized through a well-arranged ”Graphical User Interface GUI”.
