Fan motors are very simple in construction. They consist of a synchronous or asynchronous electric motor, with a fan wheel of the associated shaft, and the connections for the lines. However, DC motors are used (e.g. in computers or in a car).The fan motor is a fairly uncomplicated yet vital part of an air conditioner. It’s the part of the unit that pumps air through the system. Without that circulation of air, your AC won’t cool your home.
What is the function of fan motor?
An AC fan motor plays the vital role of turning the fan to keep air moving. This allows hot air from inside the house to be blown outside so that cool air can be moved through the ducts and into the rooms.
What is the difference between a fan motor and a blower motor?
What Is a Blower Motor? Unlike the condenser fan motor, the blower motor is located indoors. It's the component that blows cool air through the ducts and into different parts of your home. So it's essentially your air mover.
What type of motor is in a fan?
In conventional ceiling fans, single phase induction motor is used. These motors consume minimum power and hence, are also known as fractional kilowatt motors. A single phase induction motor requires only one power phase for operating. It converts the electrical energy from the power input into mechanical energy.
What happens if fan motor fails?
Without a functioning fan or furnace blower motor, your AC is rendered useless. This could also mean that you need a furnace repair or start looking at blower motor replacement cost. You'll either suffer no air or weak airflow.
What is the function of fan motor?
An AC fan motor plays the vital role of turning the fan to keep air moving. This allows hot air from inside the house to be blown outside so that cool air can be moved through the ducts and into the rooms.

What causes fan motor to overheat?
A typical reason for your blower motor overheating is a clogged air filter. When the air filter is clogged, the blower motor has to work harder to pull warm air into the system, which can cause the motor to overheat. To keep your fan motor from overheating, you'll want to check your air filter every 2 months.
How much does it cost to replace a blower motor?
What's the difference between a fan and a blower?
The term blower is sometimes used interchangeably with fan. In general, a blower has a slightly higher pressure rise than a fan: from 1.11 to 1.2. Here again, pressure rise is defined as discharge pressure over inlet pressure. Blowers are used in situations where the system resistance is higher than that for a fan.
Are fan motors AC or DC?
Most ceiling fans, as well as most household appliances, use AC motors, as AC is the type of current distributed by power companies. AC motors function by being connected directly to a power source. This power source is what creates the moment of force required to rotate the motor's rotor.
How does a fan move air?
When a ceiling fan rotates counter-clockwise, the force of the spinning blades suck the hot air around and above the ceiling towards the fan. After the hot air gets sucked into the blades, it's simultaneously “cut,” accelerated, and pushed downward into the room as a breeze.
Why capacitor is used in fan?
The capacitor is used not only to start the fan but also to make it spin. In simple words, the capacitor creates a magnetic flux (torque) which makes the fan rotate. Generally, two capacitors in parallel series are used in the ceiling fan.

What causes fan failure?
Causes of inadequate airflow to the fan include a backwards installed or running impeller, improper blade angle setting, missing cut-off, an impeller not centred with inlet collars, slow fan speed, dirty or clogged inlet, improper running clearance or improper inlet cone-to-wheel fit.
Why is capacitor used in fans?
The capacitor is used not only to start the fan but also to make it spin. In simple words, the capacitor creates a magnetic flux (torque) which makes the fan rotate. Generally, two capacitors in parallel series are used in the ceiling fan.
What is AC motor and how it works?
An AC motor is a motor that converts the alternating current into mechanical power. The stator and the rotor are important parts of AC motors. The stator is the stationary part of the motor, and the rotor is the rotating part of the motor. The AC motor may be single-phase or three-phase.
What is the function of fan motor?
An AC fan motor plays the vital role of turning the fan to keep air moving. This allows hot air from inside the house to be blown outside so that cool air can be moved through the ducts and into the rooms.

How long do AC fan motors last?
The average lifespan of an AC fan motor is about 12 years. An AC fan motor can last more than 12 years if it's kept clean and cooled as needed. On the other hand, without annual maintenance checkups, your fan motor may only survive between one and three years.
How long does it take to replace AC fan motor?
A professional HVAC technician can replace a condenser fan motor in one to two hours, though most technicians will also conduct an inspection and potentially replace other parts at the same time, meaning a full repair may take longer.
When should I replace my AC fan motor?
If you don't feel any airflow coming out of the vents, it may mean that a problem with the blower motor has developed to the point where the component is entirely inoperable. In this case, you'll have to replace it with a new motor.
What happens if a fan motor overheats?
If the motor itself overheats, it will stop working, and the HVAC system will have no way to cool itself, eventually causing the system to fail.
Can electric fans catch fire?
How do I know if my fan is overheating?
Listen to the sound of your computer's CPU fan. When a computer is overheating, the fan usually blows harder for a longer time in an effort to increase airflow and lower the temperature. Likewise, listen for loud or unusual sounds that may indicate the fan is failing.
How long do blower motors last?
What is a fan motor on an air conditioner?
The fan motor is a fairly uncomplicated yet vital part of an air conditioner. It’s the part of the unit that pumps air through the system. Without that circulation of air, your AC won’t cool your home.
What is a fan powered by?
This may direct the airflow, or increase safety by preventing objects from contacting the fan blades. Most fans are powered by electric motors, but other sources of power may be used, including hydraulic motors, handcranks, and internal combustion engines . Mechanically, a fan can be any revolving vane, or vanes used for producing currents of air.
Why is it important to maintain the fan motor?
As the fan blades turn, your air conditioning unit will continue to blow cool air in the entire house. Thus, it is important to maintain the fan motor to keep up the cooling process.
How to choose the right fan motor for your home?
You’ll need to consider your fan’s drive arrangement and one more factor that frequently gets missed: frequency of the motor’s input power. Let’s consider direct-drive fans first. With the fan wheel mounted to the motor shaft or the fan shaft directly coupled to the motor shaft, the motor speed should match the fan’s operating speed.
