A brushless DC motor, also known as a electronically commutated motor, is a type of electric motor that uses electronic commutation instead of brushes and a mechanical commutator, which are commonly found in traditional DC motors. Brushless motors are used in industrial positioning and actuation applications. Brushed motors Brushed motors are the simplest and most frequently used motors, especially for basic industrial equipment and low-budget applications. The misalignment generates a torque that tries to realign the fields. A typical brushless motor has permanent magnets that rotate around a fixed armature, eliminating problems associated with connecting current to the moving armature. Intermediate Join thousands of engineers who never miss out on learning about the latest product technology.
