Figure 1. Three-phase BLDC motor drive overview
Introduction
Cordless power tools are becoming increasingly popular in professional and DIY usage due to their ease of use, portability, and increased safety over mains-powered tools. With the inclusion of brushless DC (BLDC) motors, they are now suitable for most tasks.
However, manufacturers are being chal
