Power of brushless gear motor controller

Brushless gear motor controller belongs to a type of controller, then what's the advantage of it? Below small make up to say simple. 1. Suitable for use in a quiet place such as Banks, airports, schools, because the runtime small voice. 2. No carbon brush, no spark of when use produce, can be used in places where inflammable and explosive. 3. Through the controller to replace the commutator and carbon brush, guarantee the service life is longer. 4. Adopts magnetic field induction method, the need for substantial contact, to ensure the good running speed. Above is the advantage of gear brushless motor controller, hope to be of help.
