| 摘要 |
The present invention relates to a wound synchronous motor used in a drive system of an electric vehicle, which can reduce costs by using a rotary transformer identical to one used in a motor and be easily installed in a motor housing. The wound rotor synchronous motor of the present invention comprises a first stator including a first stator winding and immobilized in a motor housing; a first rotor including a first rotor winding and connected to a motor shaft; and a power transfer device including a second stator winding and a second rotor winding, inducing current by receiving external power, and supplying the induced current to the first rotor winding. Accordingly, the wound rotor synchronous motor can supply power to the first rotor winding thereof without mechanical contact. |
