本文转自稚晖君在知乎上的技术文章。 前阵子工作太忙，好久没做个人项目了，最近久违地想做一个机器人项目玩，设计中需要用到高性能超小体积的伺服电机。 电机这一块性能满足项目需求的基本上只有无刷电机可以选了--又要大功率、大扭矩，又要体积小 ...

在初学者学习FOC的过程中，往往会提出一个非常常见的问题，初学者往往卡在这里很长时间。 在SVPWM模块里，需要判断电压矢量的扇区，既然知道了电角度，为什么还要判断扇区呢？ 初学者往往认为，电压矢量的角度是等于电角度的。 事实果真如此吗？ 以上图 ...

Texas Instruments has announced its InstaSPIN-FOC (field-oriented control) motor control solution – a sensorless software-based solution built on its FAST (flux, angle, speed and torque) algorithm.

High-performance motors need a control mechanism that ensures enhanced smoothness, reliability, and efficiency. One of the most apt examples of such an application is the motor used in ...

An average electric vehicle (EV) user has no idea about Field-Oriented Control (FOC) algorithm that works silently under the hood. But people in the know of things will swear by its ability to drive ...
