<p align="justify" class="p" style="background: rgb(255, 255, 255); margin: 0px 0px 10px 0pt; border-radius: 0px !important; text-align: justify; color: rgb(0, 0, 0); text-transform: none; line-height: 25px; text-indent: 0pt; letter-spacing: normal; font-family: 微软雅黑, "Open Sans", sans-serif; font-size: 13px; font-style: normal; font-weight: normal; word-spacing: 0px; white-space: normal; box-sizing: border-box; orphans: 2; widows: 2; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px;"><span style="border-radius: 0px !important; box-sizing: border-box;">频闪仪频率为电机转速的</span>n倍，可以看到n个标识。</p>
<p align="justify" class="p" style="background: rgb(255, 255, 255); margin: 0px 0px 10px 0pt; border-radius: 0px !important; text-align: justify; color: rgb(0, 0, 0); text-transform: none; line-height: 25px; text-indent: 0pt; letter-spacing: normal; font-family: 微软雅黑, "Open Sans", sans-serif; font-size: 13px; font-style: normal; font-weight: normal; word-spacing: 0px; white-space: normal; box-sizing: border-box; orphans: 2; widows: 2; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px;"><span style="border-radius: 0px !important; box-sizing: border-box;">电机转速测试办法</span></p>
<p align="justify" class="p" style="background: rgb(255, 255, 255); margin: 0px 0px 10px 0pt; border-radius: 0px !important; text-align: justify; color: rgb(0, 0, 0); text-transform: none; line-height: 25px; text-indent: 0pt; letter-spacing: normal; font-family: 微软雅黑, "Open Sans", sans-serif; font-size: 13px; font-style: normal; font-weight: normal; word-spacing: 0px; white-space: normal; box-sizing: border-box; orphans: 2; widows: 2; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px;">1、“标识”出要测量的目标物体，可经过固有的区别特质（如标签、划痕等）或用尺、铅笔在外表做记号。</p>
<p align="justify" class="p" style="background: rgb(255, 255, 255); margin: 0px 0px 10px 0pt; border-radius: 0px !important; text-align: justify; color: rgb(0, 0, 0); text-transform: none; line-height: 25px; text-indent: 0pt; letter-spacing: normal; font-family: 微软雅黑, "Open Sans", sans-serif; font-size: 13px; font-style: normal; font-weight: normal; word-spacing: 0px; white-space: normal; box-sizing: border-box; orphans: 2; widows: 2; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px;">2、将频闪频率先从低往大调理，当呈现单个静止的标识时，记下频闪仪的显示频率值，该值有能够为电机实际转速值或n分之一倍。</p>
<p align="justify" class="p" style="background: rgb(255, 255, 255); margin: 0px 0px 10px 0pt; border-radius: 0px !important; text-align: justify; color: rgb(0, 0, 0); text-transform: none; line-height: 25px; text-indent: 0pt; letter-spacing: normal; font-family: 微软雅黑, "Open Sans", sans-serif; font-size: 13px; font-style: normal; font-weight: normal; word-spacing: 0px; white-space: normal; box-sizing: border-box; orphans: 2; widows: 2; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px;">3、调整频闪仪的频率为前面记载频率的2倍（运用×2按钮或许是旋钮调理），看静止的标识图案个数是否呈现了2个。</p>
<p align="justify" class="p" style="background: rgb(255, 255, 255); margin: 0px 0px 10px 0pt; border-radius: 0px !important; text-align: justify; color: rgb(0, 0, 0); text-transform: none; line-height: 25px; text-indent: 0pt; letter-spacing: normal; font-family: 微软雅黑, "Open Sans", sans-serif; font-size: 13px; font-style: normal; font-weight: normal; word-spacing: 0px; white-space: normal; box-sizing: border-box; orphans: 2; widows: 2; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px;">4、反复步骤3，直到呈现2个静止的标识，则现在频闪仪显示的频率值为实际电机转速值的2倍。即：实际电机转速值=当前频率值/2。</p>
