Electromechanical Training System



The Electromechanical Training System combines a modular design approach with computer-based data acquisition and control to provide unrivaled training in electromechanical systems. Training is oriented toward today's competence requirements, including electricity fundamentals (i.e., dc power circuits), single-phase and three-phase ac power circuits, power transformers, three-phase transformer banks, permanent magnet dc motors, three-phase rotating machines (induction machine and synchronous machine), and power factor correction. The system features the Four-Quadrant Dynamometer/Power Supply, and the Data Acquisition and Control Interface, two state-of-the-art USB peripherals that greatly enhance the learning experience of students.

The courseware in the Electromechanical Training System provides students with a sound knowledge of basic electric power technology, including the operation of the permanent magnet dc motor, three-phase induction machine, and three-phase synchronous machine, three rotating machines that are commonly used in numerous applications today.

Two other rotating machine courses from the Electric Power Technology Training Program can be optionally added to the Electromechanical Training System. These courses complete student training in rotating machinery by adding knowledge of the following conventional rotating machines: separately excited, shunt, series, and compound dc motors, separately excited, shunt, and compound dc generators, universal motor, and single-phase induction motor (capacitor-start and split-phase types). These machines, although still in use today, are less common in modern applications.

Features & Benefits

  • The training system teaches the principles of three-phase rotating machines. To this end, students follow a complete curriculum that includes these topics:
    • An introduction to the fundamentals of electricity, beginning with dc power circuits and ac power circuits.
    • More advanced courses that cover different concepts and devices important to the study of three-phase rotating machines, such as single-phase and three-phase ac power circuits, single-phase and three-phase power transformers, and power factor correction.
    • Courses that cover the operation of different rotating machines, such as permanent-magnet dc motors, induction machines, and synchronous machines.
    • Optional courses that cover less common machines, such as conventional dc machines, universal motors, and single-phase induction motors.
  • The course curriculum of the Electric Power Technology Training Program is highly flexible and allows a multitude of different customized training solutions.
  • The courseware includes student manuals and instructor guides with all the theory required to perform the hands-on experiments.
  • All workstations, modules, and components are very sturdy to ensure a prolonged service life in a demanding environment such as a training laboratory.
  • The modular design approach of the training equipment allows a large variety of courses to be performed using a small number of modules, without unnecessary duplication of equipment.
  • All electrical components can be interconnected without electric shock hazard since all live parts of the connection leads are concealed and insulated.
  • All electrical symbols representing the components used in a laboratory exercise are clearly silk-screened on the front panel of the modules.
  • The training system includes two highly versatile USB peripherals:
    • Four-Quadrant Dynamometer/Power Supply, Model 8960-2. This module is used as a dc and ac power source. it can also be mechanically coupled to all rotating machines to operate as a prime mover or brake.
    • Data Acquisition and Control Interface, Model 9063. This module gives access to a large variety of computer-based measuring instruments via the LVDAC-EMS software.
  • Software upgrades for LVDAC-EMS and firmware upgrades for the Four-Quadrant Dynamometer/Power Supply and Data Acquisition and Control Interface are available for download free of charge on the Festo Didactic website.
