1, Durability: Brushless motor has no brush, no friction and wear, brushes of brushed motor will wear and need to be replaced more frequently, which reduces the life of the treadmill.
2, more energy-saving, quieter: Brushless motor is more efficient, can provide greater output at lower power, and can better control the speed and load of the treadmill. Brushless motors are quieter because they have no friction and noise generated by brushes.
