提高电机稳态过载能力是许多直驱方式的电机调速系统所关注的重要问题。针对该问题，以无阻尼绕组电励磁三相隐极同步电机为研究对象，提出了一种基于q轴气隙磁链定向的电流协调控制策略，用定子q轴电流产生气隙磁场，转子电流用作转矩电流。对电机在采用该策略时的稳态特性进行了分析，并与传统气隙磁链定向矢量控制策略进行了比较，通过实验对该策略的有效性进行了验证。

The improvement of overload capability has always been the essential issue in the direct drive motor system.For the electrically excited three-phase non-salient synchronous motor with no damping wind-ings, a q-axis air flux oriented strategy with the coordinated control of stator and rotor currents was proposed . In this strategy , the q-axis current built the air field while the rotor current was used as torque current .The steady characteristic of the motor in this strategy was analyzed in detail and compared with the traditional air flux oriented strategy .The experiments validate the effectiveness of the proposed strategy .
