Diagram of a fan

Table fan: Basic elements of a typical table fan include the fan blade, base, armature, and lead wires, motor, blade guard, motor housing, oscillator gearbox, and oscillator shaft. The oscillator is a mechanism that motions the fan from side to side.

What are the 4 wires on a fan?

Pin Name		Color
1	Ground	Black
2	+12v	Yellow
3	Tach/Signal/Sense	Green
4	Control/PWM	Blue

How does a fan work step by step?

The ceiling fan has a motor that converts electrical energy into mechanical energy. First, the capacitor of the ceiling fan torques up the electric motor, thereby causing it to start and run. As the electrical current reaches the motor, it enters coils of wire that are wrapped around a metal base.

What are the parts of a fan motor?

Motor – The heart of the fan consisting of the armature, bearings, windings, rotor, stator, and shaft.

What are the parts of a standing fan?

Hub/cap – it is a device which connects the fan blade with the motor. Extension pole – this is the component that makes stand fan special, it allows the user to adjust the height of the fan according to their preference. Head support frame – this component gives the stand fan its feature of tilting its head up or down.

How many parts are there in fan?

Household fans usually have 4 or 5 wooden blades, a decorative motor housing, and a standard three speed motor with pull-chain switch control.

How do you wire a ceiling fan with 4 wires?

Connect the white wires (neutral wires) from your fan and ceiling together. Connect the green wire to your household ground wire (copper/bare wire). Connect the black wires together. Connect the blue wires together or the blue wire to the black wire for lights.

What are the 3 wires on a fan?

A 3-wire fan has power, ground, and a tachometric (“tach”) output, which provides a signal with frequency proportional to speed.

What do I do with the red wire when installing a ceiling fan?

A red wire up in the ceiling fan junction box usually indicates that the wiring has been installed which provides separate switch for the light and a separate switch for the fan motor. If your ceiling fan does not have a light fixture, then simply cap off the red wire and attach the fan motor to the black wire.

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.

How does a fan rotate?

A Fan comprised of a motor run by electric current, which is attached to fan blades by a shaft. This rotor shaft is run by the motor that makes the shaft rotate around d its axis, and turns the fan blades, at different speeds, depending upon the speed set for the motor.

How does electricity spin a fan?

An electrical current reaches the motor and then enters coils of wire wrapped around a metal core. When this current passes through the wire, it creates a magnetic field that makes it rotate. 4. In this way, the electric energy is converted into mechanical energy and causes the motor coils to spin.

What is the 7 main components of electric motor?

Different Parts of an Electric Motor and Their Function

A power supply – mostly DC for a simple motor.
Field Magnet – could be a permanent magnet or an electromagnet.
An Armature or rotor.
Commutator.
Brushes.
Axle.

What are the parts of electric fan and explain its working?

Electric fans have a motor that turns a shaft on which there is an impeller. The turning impeller creates air pressure, causing air flow. If the fan moves air in the same direction as its shaft, it is axial flow. Propeller fans are axial flow.

What is the use of capacitor in fan?

As a result, a capacitor is employed in a fan to generate a phase difference in the current of the two windings, which produces a magnetic flux and causes the fan's rotor to move.

What is the function of the fan?

Fans are used for circulating air in rooms and buildings; for cooling motors and transmissions; for cooling and drying people, materials, or products; for exhausting dust and noxious fumes; for conveying light materials; for forced draft in steam boilers; and in heating, ventilating, and air-conditioning systems.

What are the external parts of a ceiling fan?

Construction of Ceiling Fan

Why do fans have a circle in the middle?

Because, a fan rotates about it's center. A circle is uniform and all other shapes are non-uniform. A non-uniform shape easily gets unstable at higher velocities due to uneven distribution of mass. Even if you try to keep a quadrilateral frame, your rotor should be circular to be stable.

How many types of fan are there?

How many types of fans are available? There are two main types of exhaust fans: Axial Fans: These fans look like propellers and draw air straight through the fan. Centrifugal fans: These fans look like "squirrel cages" that draw air into the centre of the fan and exhaust it at a 90-degree angle.

Which motor is used in ceiling 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.
