    Abstract: A synchronous motor is provided with starting resistors connected on each field coil or between pairs of field coils so as to confine the induced field current to only the portion of the field coils nearest the air gap. This results in less flux leakage and increases the contribution to pull-in torque of the field coils near synchronous speed so the machine can be brought into synchronism with a higher load torque than otherwise.

    Abstract translation: 同步电动机设置有连接在每个励磁线圈上或在两个场线圈之间的启动电阻器,以便将感应的场电流限制到最靠近气隙的励磁线圈的部分。 这导致更少的磁通泄漏,并增加对同步速度附近的励磁线圈的拉入转矩的贡献,使得机器可以与其他方式相比具有更高的负载转矩同步。
