Abstract
A quenching cell including an enclosure containing at least one element for stirring a quenching gas at a pressure greater than 0.4 MPa and a synchronous electric motor capable of rotating the stirring element.
Claims11
A quenching cell comprising:
- an enclosure containing at least one element stirring a quenching gas at a pressure greater than 0.4 MPa;
- an axial flux permanent magnet synchronous electric motor rotating the at least one stirring element;
- and
- a circuit, comprising at least a first and second valve, for supplying a quenching gas to the enclosure via the first valve and the synchronous electric motor via the second valve, wherein the supply circuit maintains, via the first and second valves and during a quenching operation, pressure in the synchronous electric motor higher than pressure in the enclosure, thereby resisting flow of dust from the enclosure to the synchronous electric motor.
