Very high speed motors
Motors for very high rpm range
MMT is currently investigating very high speed drives especially for air or gas flow management, with a focus on all the specific problems related to the development of motor having revolution speeds in the range of a few tens to a few hundreds of thousands of rpms with output mechanical power of several kWs.
This includes multi-physics modeling including the various types of losses (magnetic, mechanic, aerodynamic...) and specific care about bearing and rotor design, cooling, electronic control...
Prototypes reaching revolution speeds up to 200.000 rpm have already been developed in our laboratory.
