NTC-07.24 “Electric drive with MPCS”

Br0.00

The educational laboratory stand is designed for studying automated electric drives, power conversion techniques, drive control systems, and automatic control systems. It enables research and experimental determination of the characteristics of electric motors and automatic control systems. During laboratory work, methods for determining mechanical parameters such as inertia moment and flywheel mass are examined, along with the study of speed, load, and static characteristics of various types of motors (including direct current and asynchronous motors with short-circuit and phase rotors). Special attention is given to analyzing operating modes under different loads, starting circuits, braking, and reversing. The studies also include automatic speed and current regulation systems with various controllers (proportional, proportional-integral), as well as subordinate regulation systems. An important aspect is the investigation of converters based on IGBT transistors and their characteristics. Overall, these studies aim to optimize the operation of electric drives, enhancing their accuracy, reliability, and efficiency in different modes of operation.

Structurally, the training system consists of two parts:
  • case with installed part of electric equipment, electric circuit boards, power module, countertop of integrated desktop;
  • two machine units, operating in generator-motor system. Two DC electric motors are the part of the first machine unit. One DC electric motor and one asynchronous electric motor with phase rotor are the part of the second machine unit.

The training system may be completed with electric machine units, based on the electric motor with low (90 W) or high power (0,55 kW).

Laboratory experiment may be conducted in manual mode and in the mode of the dialogue with PC.

The training system is supplied with:

  • a set of teaching materials and technical documentation intended for the teaching staff;
  • software which gives opportunity to:
    • repeat the basic theoretical principles studied in the laboratory work;
    • check students’ knowledge before performing the laboratory work (theoretical questions, correct circuit assembly, knowledge of hardware, step by step control of understanding the selection of experimental circuit and measuring instruments for the implementation of specific learning objectives).
