The applications of the electric actuators in transport require a wide operating range at constant power.

To answer this requirement, we developed a machine structure with double rotor. The separate supply of rollings up of this machine makes it possible to answer part of the operation range Torque-Speed, which is supplemented by their simultaneous supply.

Cut machine.

External axis and internal stator

The study of this machine was led within the field of a contract with the DGA, which made it possible to produce a model, and it is continuing within the framework of a PEA "electric Drive of power", with the design of a full-scale prototype.
