ROTATING ELECTRIC MACHINE, ROTATING ELECTRIC MACHINE DRIVING SYSTEM, AND RAILWAY VEHICLE |
摘要 |
To provide a high-efficiency rotating electric machine (1) by reducing a harmonic loss occurring in a stator winding, and also provide a rotating electric machine driving system and a railway vehicle using such a rotating electric machine. In a rotating electric machine (1) including: a stator (10) having a stator winding (13) including a plurality of conductors (16); and a rotor opposing the stator with a gap in between, each thickness of the conductors is set at a value equal to or less than a skin depth for a spatial harmonic of a magnetic flux in the gap. Further, such a rotating electric machine (1) is applied to a rotating electric machine driving system and a railway vehicle. This can reduce a loss attributable to a spatial harmonic occurring in the stator winding, thus permitting an improvement in efficiency of the rotating electric machine. Moreover, a loss occurring in the railway vehicle driven by the rotating electric machine driving system and the rotating electric machine can be reduced. |
