Why choose Brushless motor? What is the advantages of brushless motor :

1. Less electrical and electromagnetic noise

2. Long lifespan: No brushes to wear out, around triple lifespan as brushed motor

3. Low maintenance: No brushes to replace

4. Powerfrugal: Power consumption is 1/3 of brushed motor

5. High efficiency: Brushless motors are typically 85-90% efficient whereas brushed DC motors are around 75-80% efficient.
