This work has been divided in two main phases:
Phase 1 - Learning State of the art
View the e-Pumps families designed by Business Unit Pump Technology.
Understanding the interconnections between the physicists involved ranging from mechanics to electronics.
Catalog the products by type of electric motor and electronic control.
Phase 2 - Working on the System with Modelling approaches
Development in a 1-D environment of a numerical model of e-Pump (the pilot e-pump is produced and validated in Livorno so a lot of experimental data and all the mathematical models are available). The model will allow to develop an exhaustive vision of the product as a Mechatronic system and to make assessments on the best architecture to be implemented, in term of view of performance, refrigeration of electronic parts and, nally, global efficiency!
The purpose of this thesis is to realize a MATLAB and Simulink model of an ePump for the transmission
lubrication of the new engine Renault E-TECH Plug-In Hybrid. The system includes a gerotor
pump, BLDC motor, electronics necessary to energize the motor and the control strategy to make it
move at desired speed or with a specic torque. The real motor, after a simple test, has proven to
have trapezoidal BEMF, thus two different control strategies were applied on the pump, considering
the motor with Trapezoidal BEMF.
