The microcomputer system exactly and rapidly shows the ratio offluctuationofspeed.
准确迅速地反应了发动机转速波动规律。

In order to have a reliable operation, must reduce the speedfluctuation, namely must effectively restrain the load torque ripple and motor electromagnetic torque ripple ofspeedfluctuation bring.
为了可靠运行，必须降低转速的波动，即必须有效抑制负载转矩脉动和电机电磁转矩脉动带来的转速波动。

The performance of high speed rolling bearing was studied under unstable conditions of rotation speedfluctuation, and the failure modes of the bearing were analyzed under such conditions.
