### Goals

Part I: Hydraulic machines
This course, organized around theoretical and experimental activities, aims to train engineering students on essential concepts in hydraulic machines and their coupling with hydraulic circuits. The proposed case studies concerns concrete issues existing in the industry.

Part II: Rotating electrical machines
This teaching presents the means of converting electrical energy into mechanical energy. The different electromagnetic motor technologies will be presented and modeled (MCC, MS and MAS). The compromises and criteria for choosing / designing the machines will be discussed. Finally, an opening on “unconventional” means of conversion will be provided.

Content

Hydraulic machines:

• Notions on hydraulic machines: orders of magnitude, use and operation
• Application of conservation equations to pump geometries (Euler's theory)
• Pump / circuit coupling; choice of pumps
• Similarity in turbomachines
• Study of the phenomenon of cavitation: implantation of a machine, field of operation, cavitation erosion

Rotating electrical machines:

• Electromechanical conversion
• Direct current machines as the ideal machine to drive
• Rotating fields and study method for alternative machines
• Synchronous machines
• Asynchronous machines

Prerequisites

Hydraulic machines:

• Fluid mechanics: balance equations, hydrostatic
• Head losses and hydraulic systems

Rotating electrical machines:
Complex numbers, Phasors and Fresnel representation, law of nodes and meshs, notions of mechanics (torque, speed, force) and electromagnetism (B, H, Flux and laws: Ampere, Coulomb, Lentz theorems ...), vector product .
