| 摘要 |
The invention concerns a electrical transformer with switch flow comprising a stator (200) and a rotor (100), the stator including on its inner face a series of notches housing a series of stator coils (213), and further comprising a series of housings for excitation means, and the rotor comprising a plurality of switch flow teeth (101) for selectively making, in pairs, closed magnetic circuits passing through the stator coils. The invention is characterised in that the stator comprises a plurality of independent stator coils (213) defining as many phases and located in a series of individual cells (210) distributed at an angle on its circumference, and the rotor teeth (101) are evenly spaced at an angle such that the angular positions of the different pairs of teeth have with respect to the different individual cells predetermined phase shifts. The invention is applicable to brushless alternators for motor vehicles. |
