| 摘要 |
An electric machine ( 40 ) has a stator ( 43 ), a permanent magnet rotor ( 38 ) with permanent magnets ( 39 ) and a magnetic coupling uncluttered rotor ( 46 ) for inducing a slip energy current in secondary coils ( 47 ). A dc flux can be produced in the uncluttered rotor when the secondary coils are fed with dc currents. The magnetic coupling uncluttered rotor ( 46 ) has magnetic brushes (A, B, C, D) which couple flux in through the rotor ( 46 ) to the secondary coils ( 47 c, 47 d) without inducing a current in the rotor ( 46 ) and without coupling a stator rotational energy component to the secondary coils ( 47 c, 47 d). The machine can be operated as a motor or a generator in multi-phase or single-phase embodiments and is applicable to the hybrid electric vehicle. A method of providing a slip energy controller is also disclosed. |
