The electrical machine laboratory is a fundamental subject for all electrical engineering students and for this reason recently De Lorenzo has decided to upgrade the old laboratory equipment and to provide students with hands-on application on up-to-date electric machines, drives and instruments, as well as to improve their preparation theory learned from lectures. The benches are designed to study all types of electric machines such as three-phase asynchronous and synchronous machines, single-phase machines, direct current machines, single-phase and three-phase transformers, speed control of DC and AC motors and a bench that allows to learn the PLC programming techniques to be able to control an electrical machine driven by an inverter. Both the powers 0.3 kW (Eurolab) and 1.1 kW (Unilab) are covered by all the previous benches and their characteristic key is the total modularity and the advantage to include digital measuring units with software to acquire and process data through Modbus interface. They are recommended for high schools and first years of university.
The DL MAC-CCC is a multipurpose bench for the speed control of direct current motors of EUROLAB (0.3 kW) and UNILAB (1.1 kW) electric machines.
The DC motor speed controller is built with a single-phase semi-controlled thyristor bridge suitable for the control of the speed of independently excited DC motors by regulating the conduction period in open and closed loop.
The controller consists of three control loops: speed, current and armature voltage (for this latter it is necessary to use the isolation amplifier).
The DL MAC-CCA is a multipurpose bench for the speed control of three-phase asynchronous motors of EUROLAB (0.3 kW) and UNILAB (1.1 kW) electric machines.
The speed control can be achieved also through a manual control of a potentiometer with or without acceleration and deceleration ramps.
The variable frequency AC drive can be programmed from keyboard with on screen guide.
The DL PLC-MAC is a multipurpose bench for the study of PLC programming techniques used to start and control a three-phase asynchronous electrical motor using an inverter drive.
The starting and control of an induction asynchronous motor can be tested in two different modes:
· Manual operation using timed relays or an inverter.
· Automatic operation using a PLC to control the inverter drive and contactors.
The DL MAC-TT is a multipurpose bench for the study and characterization of single-phase and three-phase transformers of the Eurolab series EM (0.3 kW) and Unilab series UM (1.1 kW).
The trainer provides an experimental approach to the analysis of the behaviour and characteristics of the single-phase transformer.
It is composed of a supply, measurement and load unit and of two transformers.
