Energy Conversion Laboratory
Faculty in Charge: Mr. H. Alciatore
The Energy Conversion Laboratory resides in room 611 of the UNO engineering building. This lab is used primarily by the electrical engineering curriculum course ENEE3511 "Energy Conversion Lab", which is taken after a student has successfully completed the course ENEE3521 "Electric Machinery". This lab is also used for demonstrations and special lab exercises for the course ENEE3501 "Basic Electric Machinery" for non-electrical engineering students.
The ENEE3511 "Energy Conversion Lab" course is very unique. It is the only course in the electrical engineering curriculum where students have the opportunity to gain hands-on experience with power equipment including rotating electrical machinery (DC and three phase AC generators and motors) and power transformers (single phase and three phase). In this course, the students learn to use detailed wiring diagrams to connect electric machines with power sources, loads, and meters to perform many different types of tests and experiments that demonstrate the operational and loading characteristics of electric machine systems. There is also a strong mathematical modeling and calculation aspect to this course as well. Students learn to conduct standard machine tests from which mathematical models for the machines can be determined empirically. Loading tests are then done on the machines, and the measured quantities from the loading tests are compared to quantities calculated mathematically by the students using machine models and circuit analysis techniques.
The equipment used in the Energy Conversion Laboratory is manufactured by Hampden Engineering. There are three Hampden Model HMD-100CM student power consoles. Each power console is equipped with a 120/208V Three Phase Power Source, a 0-140/242V Variable Three Phase Power Source, a 0-125V 5A DC Power Source, and a 0-150V 1A DC Power Source.
The following additional equipment is located at each console.
