The widely used motor types of vacuum cleaner motors include DC motors, AC motors and brushless motors.（BLDC）
DC motor is widely used in portable vacuum cleaner and small cordless vacuum cleane,which has the characteristics of simple structure, small size, light weight and convenient starting, speed regulation, reversal,etc. At the same time, DC motor is high efficiency with long life so the cost is relatively high.
Due to the smaller size, it is widely used in portable vacuum cleaners and small cordless vacuum cleaners. These vacuum cleaners are less powerful and require small accessories such as floor heads, brushes, etc.
AC motors are usually used in vacuum cleaners with higher power and longer working time. AC motor has the advantages of low noise and long service life. However, the volume of AC motor is relatively large, requiring external power control, and there are some limitations when used.
Due to the high power and relatively large structure of AC motor, it is widely used in medium power and high power vacuum cleaners. Such vacuum cleaners need to work for a long time and have higher suction, such as hanging vacuum cleaners, handheld vacuum cleaners, wireless intelligent robot vacuum cleaners, etc.
BLDC motors have no brushes,which can greatly reduce energy consumption and extend service life. Brushless motors also have the advantages of fast response speed and high energy efficiency, so they are used in many high-end vacuum cleaners.
