Electric Wheelchair using BLDC Motor

Last Updated on May 17, 2021 by Swagatam 16 Comments

basic BLDC motor

In this post I have explained how to make a simple electric wheelchair circuit using a standard BLDC motor driver circuit, and a couple of high power BLDC motors. Introduction The introduction of electric wheelchair was like a boon to our many differently-abled friends who now find it much easier to move and travel around, […]
