Alecop’s ProLAB is the most advanced system for teaching Electrical Machines. It allows students to study, both theoretically and practically, the operation and performance of static and rotating electrical machines from a fundamental level to the most advanced tests.
ProLAB is a modular system, comprising a test bench, power supplies, instruments and various dc, single and 3-phase ac machines and transformers. It can be confi gured traditionally as single workstations, using either conventional or PC based instruments, or networked when only one set of hardware is necessary for each classroom providing a cost effective solution, and a simple upgrade path when student numbers increase. When used with a PC or networked, Diana software provides theory and instruction, as well as control, and guides the student through the construction and assembly of different test strategies. Even complex confi gurations take only minutes to complete. Diana contains standard test routines or allows the student or instructor to set up their own experiments. Each of the m`odules, whether power supplies, loads or instruments can be set up manually or via the software. The machines and test bench are also compatible with conventional instruments. Uniquely Diana contains mathematical models of each machines so the ‘ideal’ simulated test results can be directly compared to those obtained from real machines. Alternatively students can familiarise themselves with test procedures using the simulation before moving on to the actual machine. A document generator helps students produce their laboratory reports. Comprehensive
documentation is provided with experimental manuals for both the student and instructor. ProLAB can be mounted, when required, on a mobile bench for portability. Because it only requires a single phase power supply (three phase for machine operation is generated on-board), it can be used in any classroom so the days of costly dedicated laboratories are past.

Adapted to classroom needs

The BEM system enables students to learn concepts and procedures of the operation of static and rotating electrical machines.


The modular system makes it possible to acquire the components that best meet the needs of its centre, for both curriculum and budget. The BEM is compatible with conventional elements in your classroom/ workshop (resistors, inductors, capacitors, rectifier bridges…).

Time and motion economy

One machine per class is sufficient, reducing acquisition and maintenance costs.

The “199” module series, designed for this system has standard instrumentation built in.

The most complex assembly takes only a few minutes and has few cables.


The equipment returns the energy to the grid that is traditional dissipated into heat. In addition to reducing consumption, it implies the reduction of the size of the modules and bench, and the elimination of potentially dangerous hot spots.


This equipment goes beyond the current regulations relating to safety, implementing a series of added protection to prevent accidents in the field of education.

Work process

The BEM allows the student to put into practise the basic concepts learnt in the theory related to the operation of electrical machines. The putting into practise is by testing, whether real or simulated.

Each test is performed following these 6 steps:


Testing with the modules and the bench. Fieldwork. Manual demonstrations


It combines the use computer to prepare exercises and sending the manual application, to the machine bench.


Enables the entire work process to be carried out through the software. The library has the most significant test activities to achieve global learning.


Students in the class are kept active thus avoiding, as far as possible, waiting times. Classroom connectivity completes the work:

non-networked, students work individually on their computers and run the test manually or from the teacher’s computer.

Having a local area network enables tests to be carried out from any computer and enables optimal file and activity sharing.

If Internet is added, the users who are not physically in the classroom, may access the test bench thus facilitating distance learning.
