Subjects
*PULSE width modulation transformers, *POWER transformers, *ELECTRIC potential, *BRUSHLESS electric motors, *POWER transmission
Abstract

At present the brushless DC motors find increasingly wider application, thus different methods for their control are developed. The paper presents varieties of pulse-width modulation applied in control of these types of motors. It is researched, analyzed and evaluated the energy exchange between motor and power source using the unipolar modulation of upper and lower transistors of voltage invertor, PWM_PWM and PWM_ON modulation. The load characteristics in each of examined PWM technics are researched, as well. [ABSTRACT FROM AUTHOR]

Subjects
*STEPPING motors, *ELECTRIC motors, *ELECTRIC potential, *ELECTROMECHANICAL devices, *ELECTRICAL engineering
Abstract

Development of the modern power electronics puts serious challenges to the teaching of the industrial electronics students, due to the complexity of the necessary knowledge and skills. In this paper we discussed the teaching methodology of stepper motors control, using Texas Instruments platforms and the main points of the students teaching process during the laboratory work.
