Study on the Characteristics of Electronically Commutated Motor

  • B. Karaliunas


The article presents the study on the electrically commutated DC motors or on the so called studies of the fields of application of brushless motors, considering their advantages and disadvantages. The computerized simulation model Matlab/Simulink of the characteristics of the EC motor was compiled, their units of operation were described as well as the methodology of their simulation. There are presented the curves of the change of the electromotive force induced in the phase winding of the motor, the cur rents and the moments of the motor under the various velocities of the rotor rotation. The obtained results indicate that the efficiency of the commutated motor depends on the accuracy of the commutation moment of the stator windings.
