Arduino Mega 2560 是基于 ATmega2560 的微控制器板。它具有 54 个数字输入/输出引脚(其中 15 个可用作 PWM 输出)、16 个模拟输入、4 个 UART(硬件串行端口)、一个 16 MHz 晶体振荡器、一个 USB 连接、一个电源插孔、一个 ICSP 接头和一个复位按钮。它包含支持微控制器所需的一切;只需使用 USB 数据线将...
正弦驱动:这种驱动方式可以改善电机运行效果,使输出力矩均匀,但实现过程相对复杂。同时,这种方法又有 SPWM 和 SVPWM(空间矢量 PWM)两种方式,SVPWM的效果好于 SPWM。 2 PWM调速原理 PWM 调速实质上是调节占空比,我们一般是根据占空比的大小来衡量速度,占空比是高电平在一个周期之中的比值,高电平的所占的比值越大,占...
