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 ...

SVPWM是空间矢量脉宽调制(Space Vector Pulse Width Modulation)的简称，通常由三相逆变器的六个功率开关管组成，经过特定的时序和换相所所产生的脉冲宽度调制波，最终输出的波形可能会十分接近理想的正弦波形。具体如下图所示；左侧为复平面，即空间矢量，右侧 ...

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 ...
