Simple maintenance of brushless motors.
Carbon brush motors require replacement of carbon brushes, which can cause damage to the motor if not replaced in a timely manner. Brushless motors have a long service life, usually more than 10 times that of brushed motors, but if they break down, they need to be replaced, but daily maintenance is basically not necessary.
The noise aspect is not related to whether there is a brushed motor, but mainly depends on the fit between the bearings and the internal components of the motor.
The parameter indicators of a model brushless motor, in addition to external dimensions (outer diameter, length, shaft diameter, etc.), weight, voltage range, no-load current, maximum current, etc., also include an important indicator KV value, which is a unique performance parameter of brushless motors and an important data for judging their performance characteristics.
