About the BLDC motor:
- Brushless DC motor, also referred to as a BLDC, BL or EC (electronically commutated)
motor
- Conventional DC motors have carbon brushes. Carbon brushes are subject to wear and
cause high-frequency interference owing to the "coal fire".
- As the name implies, BLDC motors work without carbon brushes. The traditional
drawbacks no longer apply; the motors are non-wearing and no disturbances are
produced. The coils are electronically controlled, which means an electronic control
system is required. In many cases, this is already integrated in the motor.
