The board, allowing the simulation of starting systems for the motors with squirrel cage rotor, is equipped with a clear synoptic diagram that shows through terminals: the push-buttons, the thermal relay contacts, the contactor coils and the signalling lamps.

The system has been designed for the study of programmable logic control techniques in the control of the speed of a separately excited dc motor. The speed regulation includes two control loops: hardware current loop with over-current limiting and speed loop with external PLC control. Speed measuring with a tachogenerator or with an opto-encoder via frequency/voltage converter.

Didactic system for the study and training of servo-motors and controllers. It includes a transistorized digital servo-converter with control through PWM vector modulation, for brushless alternating current servo-motors driving in four quadrants.

This training system has been designed for the study of the theoretical concepts and the solution of problems related to the process of speed control of AC machines.
