【摘要】 原有的时栅传感器设计中采用了电机绕组产生旋转磁场的方案,但是电机定子绕组分布不均带来了误差。原有的差线栅传感器中采用了齿栅的结构,但实验表明它对齿的加工精度太敏感。本文提出了一种新的行波形成方法,实验表明,按此方法设计的新的传感器,可以解决上述2个问题。更多还原

【Abstract】 Three-phase winding is used to generate rotating magnetic field in designing time grating sensor, however uneven distribution of the winding may arouse measurement error.Tooth-grating structure is a- dopted in designing differential grating sensor,and the precision of the sensor is very sensitive to the machi- ning precision of the teeth.To solve aforementioned two problems,a new method of generating traveling wave was firstly proposed,and a novel type of time grating sensor was developed.Experiment results show the effectiveness of the proposed method.更多还原
