R&D Case

Micro DC brushed motor and DC brushless motror are used for robot cleaner.

The brushless DC motor has long life time and low noise.

The life time of  brushed DC motor is relative shorter and the noise is bigger than brushless motor’s.

The price of brushed DC motor is much cheaper than brushless DC motor.

So the brushed DC/AC motor is often used in low-end market and the AC/DC micro brushless motor is usually used in high-end market.
