Test Bench

Electric Machines » Test Bench

An electric machine is a general term for machines using electromagnetic forces; it is a device that converts mechanical energy into electrical energy (Generator) or vice versa (Motor). Electric machines also include transformers, which do not make conversion between mechanical and electrical form and do not have any moving parts but they convert AC current from one voltage level to another voltage level keeping the same frequency. The Test bench, proposed here by De Lorenzo, is a multipurpose bench for the study and the deepening of Eurolab (0.3 kW) and Unilab (1.1 kW) laboratories. It is composed of a prime mover controlled by an inverter, a user interface with data acquisition software using the Modbus protocol and developed in LabView, an HMI gateway allowing the use of the prime mover as drive or load and instruments that carry out mechanical as well as electrical data. Beside this basic bench, the client can choose from a complete list of machines and accessories what he needs to study in depth. It is recommended for high schools and first years of university.

Products Details

The DL EM-TEST is a multipurpose bench for the study and characterization of the Eurolab series (0.3 kW) and Unilab series (1.1 kW) electric machines using an automated test approach.

The system is composed of the following main sections:
Prime mover: A squirrel cage three-phase asynchronous machine controlled by an inverter in four quadrant operation providing the mechanical power and torque necessary for the characterization of the machine under study.
Data acquisition software for electric machines: performs the test automation and provides the user interface to execute the experiments. The SW developed in LabVIEW communicates with the acquisition devices via serial port using the Modbus protocol, reading electrical and mechanical data from instruments.
HMI gateway: provides the commands to the prime mover, so it can be used as drive, load or a speed and torque control to put the machine under test in a specific working condition or to simulate different load profiles such as fan, lift, etc.
Instruments: collect mechanical (speed, torque and temperature) as well as electrical data (AC and DC, Voltage, current and Power).

DL EM-TEST

The DL MAC-E is a multipurpose bench for the study and characterization of all the electric machines in the De Lorenzo Eurolab series (0.3 kW) catalogue. The system includes all the instruments necessary to learn the operation and characteristics of each type of electric machine (motors or generators in AC or DC).

The laboratory has been designed as a modern and practice-oriented training system for vocational and engineering education. It provides a comprehensive solution to cover a standard electrical machines course that can be tailored to the institute’s educational needs.

The test bench is modular and can be reconfigured according to the machine under test using, as needed, the power supply, the electrical and mechanical instruments and the electromagnetic brake for the characterization of the motors or the prime mover (DC machine) for the study of generators.

DL MAC-E

The DL MAC-U is a multipurpose bench for the study and characterization of all the electric machines in the De Lorenzo Unilab series (1,1 kW) catalogue. The system includes all the instruments necessary to learn the operation and characteristics of each type of electric machine (motors or generators in AC or DC).
