| Comparing point | Brushless DC motor | Brushed AC motors |
Picture |  |  |
Application | Widely used on the equipment of high control requirements and high speed, such as high-end hair dryer, the model airplane, precision instruments. | widely used on hair dryer,home appliance,fan,blower etc. |
Life | Generally is tens of thousands of hours, but different bearings has different service life. | Generally is several hundreds hours or about 1000 hours.Due to the abrasion of carbon brush,it should be replaced if carbon brush was worn out. |
Effect | Adopt the speed by software PCBA, it's easy to adjuct and control. | Normally,brushed motor has a constant speed after starting,it's uneasy to change the speed.Ac universal motors have a speed at about 16000 r/s, the service life is much shorter |
