A new video from Thinking Techie offers a comprehensive overview of DC motor technology, breaking down the inner workings of both brushed and brushless DC motors. This ten-minute presentation serves as an excellent resource for anyone looking to understand the fundamental principles behind these essential components in modern electronics.
The video begins with an exploration of basic magnetic effects, establishing a foundation for understanding how motors function. It then delves into two-wire brushed DC motors, which are commonly found in various applications. The discussion transitions to three-wire brushless DC motors, or BLDC motors, emphasizing their significance in today’s technology landscape.
While many may find the terminology surrounding BLDC motors confusing, the video clarifies that the three wires correspond to three power phases. This differs from the wiring in radio-controlled (RC) servos, which typically include positive, negative, and signal leads. Notably, the BLDC motors used in computer fans do utilize positive, negative, and signal pins. This is due to the integrated controllers found within the fan housing, similar to those in RC servos.
For viewers interested in further exploration of BLDC technology, the video also highlights additional resources. Audiences can gain deeper insights by checking out “Take A Ride Through The Development Of A Custom BLDC Motor Controller,” as well as “Moteus Open Source BLDC Controller Gets Major Upgrade.” These supplementary materials provide valuable context and technical depth for those eager to expand their understanding of DC motors and their applications.
Overall, this video serves as an informative guide for novices and experienced individuals alike, making it a worthwhile addition to anyone’s learning agenda.
