摘　　要：在现有的磁电型转矩转速传感器的基础上，提出了一种新型相位式磁栅转矩转速传感器。该传感器基于相应转矩测量原理，以磁栅为信号发生器。除了具有工作频率高，输出信号波形质量好的优点外，它的另一特点是：共有四路输出信号，其中两路为反映转矩信息的比相信号，另两路是用于提高比相精度和判别转矩方向的辅助测量信号。而现有的转矩转速传感器只有两路比相信号输出。From the existing electromagnetism torque-speed transducers,a new type of phase magnetic-grid torque-speed transducer is proposed,in which the magnetic-grid is used as a signal generator.Besides the advantages of high work frequency and good quality in output signals wave shape,the transducer possesses the characteristic of owning four output signals.In the four output signals two are the signals used for comparison between the two phases and another two are the supplementary test ones used for improving phase-compared accuracy and distinguishing torque direction,While the existing toque-speed transducers have only two phase-compared output signals
