The goal of the ELIMPUS project is to provide a new electromagnetic propulsion kit based on high-speed electric machine (HS-EM), running at 20000 r/min, connected to a magnetic gear with variable transmission ratio (MG-VT): 1/16, 1/8, 1/4. Such a system should allow speed variation without the need of linking multiple gears, will be energy efficient, will produce reduced noise and will be easy to install on light EVs (such as open source vehicle, [10]). Through an active electromagnetic system (fed from a dc/dc converter) the MG ratio will be changed; the obtained MG-VT solution will be patented. Unlike other electric propulsion systems (such as Renault-Twizy, where a second motorization should be used for increased speeds), there is no need to change the motorization, because the proposed ME-MV + RM-TV system will multiply 4 times the speed!
For this electromagnetic propulsion kit we will implement the following objectives:
1. Design and structural analysis of purely electromagnetic propulsion.
For this objective we will do a design, simulations and optimization of the electromagnetic propulsion kit, using analytical methods based on electric-thermal-magnetic equivalent circuit, we will implement co-simulation for evaluating the behavior of the motor-gear system.
2. Testing and validation of purely electromagnetic propulsion.
We will build and test the propulsion system components: a high-speed electrical machine (HS-EM), a magnetic gear with variable transmission (MG-VT), the converters associated to the EM and MG, an optimal control strategy for energy management will be elaborated for the entire electromagnetic integrated system.
