Brushless motor advantages:

1, brushless, low interference

Brushless motor eliminates brushes, the most immediate change is not a spark generated by a brush motor running, thus greatly reducing the spark interference to radio remote control equipment.

2, low noise, smooth operation

Brushless motors have no brushes, friction is greatly reduced when running, running smoothly, the noise will be much lower, the advantages of the model run stability is a great support.

3, long life, low maintenance costs

Less wear brush, brushless motor primarily on the bearing, from the mechanical point of view, a brushless motor is almost maintenance-free electric motor, and when necessary, just do some maintenance to dust. On the next comparison, we know brushless motor with respect to the brush where the advantage of the motor, but everything is not absolute, brush excellent low speed torque performance, torque and other performance characteristics of the brushless motor is irreplaceable, but on the ease of use of the brushless motor, the brushless controller with the downward trend in the cost of domestic and foreign brushless technology development and market competition, the brushless power system is the rapid development and popularization stage, which greatly contributed to Development of the model movement.

Brush Motor disadvantages:

1, friction, big loss

Old die faithful before playing a brush motor when they are encountered this problem, and that is to use the motor for some time, you need to open the motor to clear the motor brushes, time-consuming to maintain as much strength to a house cleaning.

2, heat a large, short life

Due to structural reasons brush motor brush and commutator contact resistance is large, resulting in the overall resistance of the motor is large, easy to heat, and the permanent magnet is sensitive element, if the temperature is too high, the magnet will demagnetization , the motor performance, the impact there is life brush motor.

3, low efficiency, low output power

The above mentioned brush motor heating problems, largely because current acting on the internal resistance of the motor, so there is a large degree of power conversion to heat, so there is little brush motor output power, efficiency is not high.
