| 摘要 |
<p>The invention relates to an electric motor, in particular for high speed operation, comprising a motor housing ( 4 ); inside the housing ( 4 ), a stator ( 2 ) having a core ( 8 ) and windings ( 9 ) toroidally wound on the core ( 8 ); and a rotor ( 1 ) inside the stator ( 2 ). The motor comprises an inductance controlling ring ( 3 ) in soft-magnetic material around the stator core ( 8 ), increasing for each phase the leakage inductance and forming for each phase an integrated filter inducatnce (L 1 , L 2 , L 3 ) outside the core ( 8 ) of the stator ( 2 ) but still inside the motor housing ( 4 ).</p> |
