Professor Bulent Sarlioglu, CEME Collaborator, University of Wisconsin-Madison This research project presents an additively manufactured heat exchanger for rapid prototyping and active cooling of an electric machine. A rectangular in-slot heat exchanger with a coolant is used to cool the winding. The heat exchanger is optimized for a high heat-transfer coefficient, high-temperature operation, water tightness, […]
Electric Machines with Dielectric Microfluidic Cooling of Planar Windings
PhD Student: Daniel Moguel (ME) Steve Pekarek (Professor of ECE), Justin Weibel (Associate Professor of ME) Increasing the current density of windings is a means to increase the torque density, and thus the power density, of an electric machine. Recent demonstrations of planar inductors within printed circuit boards (PCB) [[1]] have demonstrated high coil current […]
Low-Cost Rapid Wide-range Adaptive Drives Using Arduino or FPGA
Yichao Tian, M.S. student of University of Michigan Ann Arbor Julia Zhang, The Ohio State University The objective of this proposed research is to set up two rapid wide-range adaptive drives using low-cost controllers. One platform uses an Arduino control unit and the other uses an FPGA controller to sense and control a permanent magnet […]
Design and Control of a Distributed Electromechanical Actuator for Bio-inspired Robots
Bonhyun Ku with Advisor A. Banerjee The spine and surrounding muscles allow vertebrates to be flexible, dynamic, and balanced. Geared motors have been used to create distributed actuation to mimic the spine in robots. While minimizing weight, the gear train trades off speed for torque to meet various design criteria. An alternative gearless, bio-inspired electromechanical […]
DC Grid Interface for Wind Energy Systems
Debranjan Mukherjee with Advisor Dr. Arijit Banerjee Offshore wind energy conversion systems are getting increased attention due to high and steady wind potential, and minimum environmental effects. As these wind farms are located far from the land (sometimes more than 100km) high power density, reliability, and efficiency are of paramount importance for the generation and […]
Primary and Secondary Control of Dispatchable Virtual Oscillator-Controlled Grid-Forming Inverters
T.G. Roberts with adviser A. Domínguez-García Grid Forming Inverters (GFMs) are a promising technology for replacing synchronous generators to sustain system voltage and frequency in microgrids with low inertia. In the U.S. bulk power grid, inertia from rotating generators helps resist sudden changes or fluctuations in frequency. Current Grid Following Inverters (GFLs) do not possess […]
Extract power from ECE Building Research Solar Panels using distributed controllers
Zhan Su, intern of A. Banerjee Illinois’s Electrical and Computer Engineering Building has sixty 400W solar panels dedicated solely for research. This project aims to create an efficient, reliable, and safe hardware framework to extract power from these solar panels and feed it to the building grid, as shown in Fig. 20 Each solar panel […]
Investigation of magnet loss in an interior Permanent magnet motor
Samith Sirimanna with advisor K. Haran Rare earth permanent magnet materials such as NdFeB magnets are the common choice for electric vehicles due to their availability and strong magnetism as well as their resistance to demagnetization. These magnets have a high electrical conductivity value, around 0.5–0.9 MS/m, which can produce significant eddy current losses. Stator […]
Ac Loss Measurement Test Bench for Measuring ac Losses in Superconducting Cables Under Transverse Rotating Magnetic Field (20-K, ¬1-T, 0–150 Hz)
Thanatheepan Balachandran with adviser K. Haran Ac losses in superconducting (SC) wires can be measured through electromagnetic methods, the heater-based calorimetric method, or the cryogen boil-off-rate-based calorimetric method. Losses must be measured in the transverse rotating field to validate the loss estimation in electrical machines. A rotating electrical field inside a cryogenic environment can be […]
Electromagnetic Modeling and Optimization of Inverter-Driven, High-Frequency, Slotless Permanent Magnet Synchronous Machines
Xiaolong Zhang with adviser Kiruba Haran High-frequency, slotless permanent magnet synchronous machines (PMSMs) can minimize the iron usage and increase the specific power. This class of machines can operate at variable speeds with an inverter drive; thus, it is promising for weight-sensitive applications such as aircraft electric propulsion systems. Figure 1 shows a 300 kW, […]
