What is the function of fan motor?

The Role of an Air Conditioner 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 a blower motor on AC unit?

A blower motor turns the fan in your HVAC unit, which causes the outgoing air to circulate out of the system and into the rooms of your home. The blower motor is the part of your HVAC system that gets your home to the temperature set on your thermostat.

How do I know what condenser fan motor I need?

Using the specifications of the fan blade is the best way to determine the correct horsepower for a replacement condenser fan motor. The diameter, angle and number of fan blades, along with the RPM of the motor, are the pieces of information necessary to make this determination.

What type of motor is in a fan?

single phase induction motor
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.

Is there a motor in a fan?

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.

What happens when AC motor goes out?

When the AC runs without the fan circulating air, it can eventually lead to the evaporator coils freezing over. Once this happens, your air conditioning unit is at risk of suffering more serious damage.

Why AC fan stops working after a while?

One of the most common reasons fans stop spinning is because of a dead capacitor. Each air conditioning system has several capacitors, including the start capacitor, which sends signals to the motor, and the run capacitor, which keeps the motor running. Capacitors can go bad over time and need to be replaced.

How do you know if a fan motor is AC or DC?

Look for the stator core construction and rotor. If there is no commutator, then it is a AC motor. If there is a commutator and brushes, it may be either a DC motor or an AC commutator motor (Universal motor).

Which motor is best for 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.
