Measuring electric currents is an essential element of many electrical systems, but doing so in a way that is as nonintrusive as possible is not an easy problem to solve. Due to this we got a wide ...
基于 STM32F407 的 20kHz 电流环 / 1kHz 速度环 / 200Hz 位置环 三轴串级 FOC 实现，支持 转矩 / 速度 / 位置三模式 在线切换。 仅用 三路霍尔传感器 完成转矩模式电流环跟踪偏差 < 0.005A，速度模式 5–3600 ...
The mechanical keyboard isn’t always so mechanical anymore. Over the past six years, keyboards with optical, Hall-effect, and other “contactless” switches have become increasingly common, often going ...
