Compared with the traditional DC motor, the electronic commutation provides higher power. Under the same speed and load, the power of the motor is increased by 20 – 30%.

In addition, brushless DC motor is more useful. It insists on high performance, while the power and power of the same conventional motor are reduced due to wear, resulting in poor contact of the brush, energy consumption of the arc between the brush and the commutator, and damage to the conductivity due to dirt.

Higher power can make brushless DC motors smaller, lighter and quieter at a given power output, thus further improving their reputation in cars, white goods, heating, ventilation and air conditioning (HVAC) and other fields. Other advantages of BLDC motor include outstanding speed and torque characteristics (torque at startup), more dynamic response, noiseless operation and higher speed scale.

The disadvantage of brushless DC motor is its complexity and related cost increase. Electronic commutation needs to monitor the circuit to ensure the accurate time of coil energization, to achieve accurate speed and torque control, and to ensure that the motor operates at high power.
