What Are the Differences Between Brush & Brushless Motors
Choosing Between Brush and Brushless DC Motors — What are the Trade-Offs?
Designing a system that involves motion and performs as intended requires choosing the right motor. Just as the conditions and specifications of motion systems vary from use case to use case, so does the optimal choice of motor. The most fundamental decision involves commutation type. In some cases, mechanically commutated brush motors provide the best solution for the budget. In other cases, only brushless DC (BLDC) motors will do. Here, we provide a comprehensive review of the technology, along with tips and tricks for choosing the right solution for a given application.
