Designed on the basis of a conventional motor, this induction machine connected to the grid provides the same power output as the machines we know. It has undergone technological and mechanical improvements that significantly reduce its impact on the environment :

• Innovative design of the magnetic circuit and low friction ball bearings to improve energy efficiency
• Plastic parts from agrochemicals that use renewable resources
• Thermoglued coils, made with UV-enamelled wire, manufactured without solvent (low environmental impact)
• Need analysis method in order to propose motors taking into account environmental footprint (with a deep life cycle analysis) and to show the rapid return on investment

The consumption of electric motors currently accounts for 70% of the total electrical energy consumed in industry. In this context, any improvement in energy efficiency in electric motor can have major impacts on the energy costs supported by the industry !

The Green Motor has proved a 1,5% improvement and two patents have been registered (in particular on the “gain oriented electrical steel”)

Applications ?

All types of electrical machines: domestic purposes (suction systems, washing machines, etc.) or industrial (pumps, fans, complex machines, etc.).

An Outstanding Prototype
