Commonly used as the brushless motor controller, then to its advantage to understand? Let's look at. 1. Runtime voice is small, suitable for hospitals, Banks, airports, schools and so on a quiet place. 2. Since there is no carbon brush, so there will be no spark when use, suitable for places where inflammable and explosive. 3. Due to its controller instead of the commutator and carbon brush, so the convenient service life is longer. 4. Due to using magnetic field induction, no real contact, thus ensuring high speed. The above is the advantage of the brushless motor controller, hope to help you.
