Suggestions for selecting motor specifications

　　1、Brushed DC motor
A brushless DC motor,also known as a DC brushless motor,works by utilizing the interaction between the brush and the annular permanent magnet to convert electrical energy into mechanical energy.Brushed DC motors have advantages such as high speed,large starting torque,and good speed regulation,making them widely used in exhaust fans.
2、Brushless DC motor
Brushless DC motor,also known as DC brushless motor,works by controlling the internal magnetic field changes of the motor through an electronic commutator,achieving the motion form of converting electrical energy into mechanical energy.Brushless DC motors are widely used in exhaust fans due to their small size,light weight,and high efficiency.
3、AC motor
An AC motor is a form of motion that converts electrical energy into mechanical energy through the magnetic force of alternating current.Its characteristics include high starting torque,smooth operation,low noise,etc.,but it is relatively power consuming.In exhaust fans,AC motors are not commonly used mainly because exhaust fans generally require low power consumption,making them less suitable for the application of AC motors.

What is the motor for a household electric fan?

　　AC motor fan
　　Although there are more and more DC fans on the market,AC fans still have strong market competitiveness due to price and cost considerations.
　　Advantages:Simple construction,sturdy and durable,and affordable price;
　　Disadvantage:The number of adjustable sections for air volume is limited,making it impossible to operate at low speeds;Stable operation,strong vibration,and people with sleep disorders may be easily awakened;Higher power consumption;Compared to DC motors,the volume is larger;Short service life
　　Purchasing suggestion:Ordinary floor fans use AC motors with large air volume and affordable prices,which is also a good choice for families with limited budgets.However,they can only be placed in living rooms,restaurants,etc.Suitable for use in large spaces such as kitchens,living rooms,etc.that are prone to stuffiness.
　　DC motor fan:
　　In order to solve the problem of noise when the fan blades rotate,modern home appliance manufacturers are gradually changing the motor of the electric fan to"DC direct current"
　　Advantages:The power consumption is only one-third of that of traditional AC fans,which is energy-saving;Can make the fan run at low speed with low noise;Generally speaking,there are more sections for air volume regulation than AC fans.
　　Disadvantage:The production cost controller requires high requirements,so the purchase price is high.

Introduction to motor types and advantages and disadvantages of exhaust fans

　　When choosing an electric fan,it is not only necessary to consider the motor specifications,but also the manufacturing quality and brand reputation of the fan.It is recommended to choose some well-known brands and quality guaranteed electric fan products.
At the same time,when using an electric fan,it is also necessary to pay attention to keeping the fan clean and maintained.Regularly cleaning the blades and motor of an electric fan can prolong its service life and ensure its good performance and healthy environmental protection.
