Team 5:Design, Control and Diagnosis of Electromagnetic and Hybrid Devices (2C2DEH).
Due to their simple and robust construction, asynchronous motors, and more particularly squirrel cage ones, account for about 90-95% of the power consumption of electric motors, which is equivalent to about 53% of the power consumption. Total electrical energy. They are widely used as electric drives in industry, public service, traction, household appliances, etc….
As the cost of energy continues to increase and the pressure caused by concern for environmental protection, manufacturers of electrical machines as well as consumers are interested in reducing the energy consumption of the systems electric. This has led to the launch of important works around the world, particularly for improving the efficiency of machines. This is mainly due to the place they occupy.
Since most electric motors used in industry are oversized, and a good number of them are subjected to a variable load over time. This means, in current practice, that they generally operate far from their nominal capacity, therefore far from their optimal efficiency and that their electricity consumption is excessive compared to the real needs. To reduce it, three solutions are proposed, namely:
- a) Adapt the speed as needed (when the engine has already been built);
- b) Optimize performance (design optimization);
- c) Carry out maintenance operations.
As part of the lab, we propose to study the control, design and diagnosis of asynchronous machines.
