轮速传感器在ABS系统中负责车轮转速信号的采集，轮速传感器性能的好坏，直接影响到ABS系统是否能正常工作，目前在ABS系统中广泛地采用变磁阻式的电磁式轮速传感器，传感器由齿圈和传感头组成，在汽车行驶过程中，车轮旋转使齿圈相对于传感头运动，传感头产生一系列频率与轮速成正比的交变电压信号[2]。

But the difference tread electrical engineering to also have some weakness, the most is economically to can't carry out scope more wide smooth adjust soon;Have to absorb the 励 magnetoelectricity of 滞 to flow from the charged barbed wire net, make a charged barbed wire net achievement a type factor to lower.

但是异步电机也有一些缺点，最主要的是不能经济地实现范围较广的平滑调速；必须从电网吸取滞的励磁电流，使电网功类因数降低。

Because the magnetoelectricity characteristic of TA is not linear, huge short-circuit current or large nonperiodic current may make the TA enter the saturated state, which cause the exportation current of the TA very small, making the busbar differential current very large.

母线区外故障时，由于带铁心TA 激磁电感的非线性特性，强大的短路电流及较大的非周期分量都可能使TA 进入深度饱和状态，此时TA 的励磁阻抗将变得很小，一次电流大部分流入励磁支路，导致TA 输出电流很小，使得母线保护差动电流很大，如果不采取一定的措施，极易发生误动。
