No commutator motor (roasted Yuushidendouki choking, Brushless Direct Current Motor) is a DC motor with the same structure as the permanent magnet synchronous motor drive built-in power supply control circuit instead of the commutator . Brushless DC motor, brushless DC motors, also called BLDC motor. Brush DC motor with high efficiency, have been widely used because it is relatively inexpensive, can be miniaturized, have life by the brush wear due to the sliding contact. Therefore, the larger motors are required to maintain replacement brush, small brush if you can not be replaced, and the life of the motor brush life. No commutator motor is replaced by the role of electronic brush (brushless DC motor) is.
BLDC motor controller Advantages
there is no commutator brushes, no need to maintain its long life.
There is no electrical brush noise.
There is no external contamination of the powder brush wear.
High-speed operation is possible because there is no contact parts.
Cons
for electronic circuitry, Environmental resistance and ambient temperature will depend on electronic components.
Expensive compared to brushed DC motor. If the current is high, especially for switching semiconductor devices are expensive
