class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt pap-left-indent-1.6em" style="line-height: 1.8;"><span style="font-size:

style="line-height: 1.8;">    直流电机的一般控制方法为使用TB6612等类似的驱动芯片,通过EN/PWM,IN1,IN2这三个信号来控制电机的方向与速度,即使经过电路简化,也依然需要1个普通IO口控制电机转动方向和1个PWM口来控制电机转速。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt pap-left-indent-1.6em" style="line-height: 1.8;">    本项目中,我另辟蹊径,采用一颗步进电机驱动芯片TMI8549来作为小车电机的驱动芯片,一颗TMI8549可以驱动两个小电机,这在体积及成本上都做到了极致的精简。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt pap-left-indent-1.6em" style="line-height: 1.8;">    我们先来看看TMI8549这颗芯片是怎么工作的:芯片有三个输入接口,分别是使能控制脚EN,信号输入脚IN1,IN2。其中IN1对应OUT1和OUT2输出,IN2对应OUT3和OUT4输出,EN高电平有效。芯片的真值表如下:</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt pap-left-indent-1.6em" style="line-height: 1.8;"><img src="//image.lceda.cn/pullimage/NCDpefFfwNQ6zuzprx97mz3VzRYHJTr6xCgIFI0U.png" alt="8549驱动芯片真值表" width="888" height="240"></p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt pap-left-indent-1.6em" style="line-height: 1.8;">    从真值表可以看出,EN给高电平,通过给输入脚IN1输入高低电平就可以控制接在OUT1和OUT2两端的电机正反转了,但是怎么才能实现控制电机的速度呢?</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt pap-left-indent-1.6em" style="line-height: 1.8;">    大家都知道直流电机是由线圈绕制而成的,那么直流电机就相当于一个大型的电感,而电感具有阻碍通过它的电流变化的能力,因此对于电机来说,PWM调速实际上是在调节驱动电机的电流,当PWM信号占空比高的时候,驱动电机的电流可以稳定在较大的值,占空比低的时候,驱动电机的电流可以稳定在较小的值。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt pap-left-indent-1.6em" style="line-height: 1.8;">    以上这些是一般的电机驱动芯片的调速原理,但是如何利用TMI8549来进行驱动呢?可能有人会想到给EN引脚输入PWM信号就可以调速了,但是TMI8549只有一个EN,但是我们需要分别调节两个电机的速度。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt pap-left-indent-1.6em" style="line-height: 1.8;">    我所使用的方法同样是利用PWM来调速,只不过稍有不同,在IN1引脚输入占空比为50%的PWM信号,则在一个PWM周期内,通过电机的电流方向为正方向半个周期,负方向半个周期,但是实际测量通过电机的电流就会发现,通过电机的电流值绝对值趋近于0。这是因为电机同样是一种特殊的电感,流过电感的电流值不会随着电压值突变。输入的PWM信号频率越高,通过电机的电流越稳定。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt pap-left-indent-1.6em" style="line-height: 1.8;">    基于以上原理,一种新的直流电机调速方式就来啦:当TMI8549的IN1端输入的PWM信号占空比为50%的时候,电机是静止状态;当占空比>50% 的时候,电机正转,占空比为100%的时候速度最大;当占空比<50% 的时候,电机反转,占空比为0%的时候速度最大。</p> <p class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt pap-left-indent-1.6em" style="line-height: 1.8;">    这种驱动方式,极大的减少了驱动直流电机对芯片IO口的占用。同时在磁悬浮装置的设计中,也可以使用这种驱动方式来控制电磁铁的极性与磁场强弱,以实现降低功耗的作用。总之这种驱动方式的妙用还有很多,期待大家一起来探索。</p> <h3 class="paragraph text-align-type-left pap-line-1.3 pap-line-rule-auto
