Laboratory facilities:

The Emerson Electric Company Machines and Drives Laboratory is valued at approximately $750,000 and is designed for computer controlled research and testing of machines and drives. It is used by faculty and graduate electrical engineering students for research and by undergraduate students for power engineering education. Computer-aided testing is accomplished by near real-time computer control of machines and simultaneous data acquisition. Data acquisition can be done as a swift sampling rate to allow for many test data points to be gathered on the state of motors. The data is easily processed and displayed for quick feedback on a test run. The laboratory consists of seven identical independent stations. Each station includes a 20-hp, 2700 rpm dynamometer, torque table, in-line torque sensor, speed sensor, voltage and current sensors, a synchronous machine excitation system, variable frequency drive system, a 230 V ac bus, a 125 V dc bus, a 250 V dc bus, as well as a tie line to the other stations. Harware-in-the-loop studies are conducted via dedicated Pentium PCs.

The Electric Drive Test Bed is a modular device, which allows a variety of power electronic architectures to be constructed. The test bed consists of 12 independent 1200 V, 200 A IGBTs with control circuitry, a forced air head sink, and a TTL interface. Instrumentation includes Hall effect current sensors, PC supervisory control systems, and a TMS320 DSP.

The High-Frequency Machines and Drives Laboratory has been expanded through recent federal and state equipment grants, and has over $350,000 of dedicated state-of-the-art equipment, including a network analyzer, spectrum analyzer, impedance analyzer, LCR meter, high-speed digital oscilloscope and TDR, dynamic signal analyzer, and power amplifier suitable for EMI measurements and parasitic characterization of systems in the 1 Hz - 500 MHz frequency range.

The combination of powerful computing facilities and software to analyze a wide range of power system problems creates an environment where students can attack research problems and complete thesis topics knowing they have the resources of current technology in both hardware and software.
