Difference between brushed and brushless motors.
The working principle is very different
A brushed motor is like an old-fashioned phonograph, which conducts current through the physical contact between carbon brushes and commutators. The rotor needs to rub tens of thousands of times to complete one revolution. Brushless motors are a product of the electronic age, replacing carbon brushes with intelligent controllers and achieving silent commutation through magnetic field induction, like invisible hands pushing the rotor to rotate.
Performance comparison can be found in the real chapter
Life comparison: Brushed motors usually only work for 1000 hours due to mechanical wear, while brushless motors easily exceed 20000 hours
Efficiency comparison: The energy conversion rate of brushless motors can reach 90%, which is 20% higher than that of brushed motors
Noise Duel: Brushed motors produce a noticeable buzzing sound while operating, while brushless motors are as quiet as a library
Applicable scenario guide
Brushed motors, with their low-cost advantage, are still active in lightweight fields such as electric toys and small household appliances. And brushless motors dominate high-end equipment such as drones and electric vehicles, especially suitable for scenarios that require precise speed regulation. When the budget is sufficient, brushless motors are always the more ideal option.
