NTC-07.31.B “Frequency converter – asynchronous motor”

Br0.00

The training laboratory stand is dedicated for studying the structure, operating principle, setting process and programming the industrial frequency converter, as well as for studying the working characteristics of the system “frequency converter – asynchronous motor”.

 
Categories: ,
Structurally the stand consists of two parts:
  • housing with installed electrical equipment, electronic cards, front panel, integrated tabletop;
  • machine unit, which includes an asynchronous electric motor with a squirrel-cage rotor, a DC electric motor of independent excitation and an optical speed sensor with determination of the rotation direction.

 The stand housing accommodates:

  • frequency converter designed to form a three-phase alternating current network of controlled frequency and voltage;
  • direct current converter dedicated to control DC motor;
  • measuring system dedicated for measuring and displaying motor parameters under study (current, voltage, electric power, speed, mechanical moment);
  • position controller for researching an asynchronous electric motor in servo mode.

At the front panel of the stand are placed:

  • frequency converter controls;
  • controls of DC converter;
  • controls of start-controlling equipment;
  • measuring system indicators;
  • connection sockets;
  • USB connector for PC connection.

The stand is accompanied with:

  • a set of teaching materials and technical documentation intended for the teaching staff;
  • software.
