Generally we use a capacitor start & run AC Motor for ceiling Fans. Working principle: whenever current carrying conductor is placed in a magnetic field-it experiences force. AC motor needs a rotating magnetic field in order to turn the rotor shaft. A ceiling fan is incomplete without these five parts which are stated below. Blades. The blades of the fans are the most common part of the ceiling fan Capacitors. Arguably the most important part of the ceiling fan is a capacitor. Motors,Pullchain Switches,Mounting Bracket. 1-Phase Capacitor start induction Motor. Working principle: whenever current carrying conductor is placed in a magnetic field-it experiences force. AC motor needs a rotating magnetic field in order to turn the rotor shaft. In a single phase system capacitor is used to provide a phase shift in the windings of the motor. The key components of a ceiling fan are the following: An electric motor Blades (also known as paddles or wings) usually made from solid wood, plywood, steel, aluminium, MDF or plastic Blade irons (also known as blade brackets, blade arms, blade holders, or flanges), which hold the blades and connect them to the motor. Flywheel, a metal, plastic or tough rubber double-torus which is attached to the motor shaft, and to which the blade irons may be attached. The flywheel inner ring is locked to the shaft by a lock-screw, and the blade irons to the outer ring by screws or bolts that feed into tapped metal inserts. Rubber or plastic flywheels may become brittle and break, a common cause of fan failure. Replacing the flywheel may require disconnecting wiring and requires removing the switch housing that's on the way for the flywheel to be removed and replaced. Rotor, alternative to blade irons. First patented by industrial designer Ron Rezek in 1991, the one-piece die cast rotor receives and secures the blades and bolts right to the motor, eliminating most balance problems and minimizing exposed fasteners. A mechanism for mounting the fan to the ceiling such as: Ball-and-socket system. With this system, there is a metal or plastic hemisphere mounted on the end of the downrod; this hemisphere rests in a ceiling-mounted metal bracket, or self-supporting canopy, and allows the fan to move freely (which is very useful on vaulted ceilings). J-hook. A type of mounting system where the ceiling fan hangs on a hardened metal hook, screwed into the ceiling or bolted through a steel I-beam. A porcelain or rubber grommet is used to keep the fan in place. This type of mounting is most common on antique ceiling fans and ceiling fans made for industrial use. A variation of this system using a U-bracket secured to the ceiling by means of lag bolts is often used on heavy-duty ceiling fans with electrically reversible motors in order to reduce the risk of the fan unscrewing itself from the ceiling while running in updraft. Some fans can be mounted using a low-ceiling adapter, a special kit which must be purchased from the fan's manufacturer. This eliminates the need for a downrod, and is therefore useful in rooms with low ceiling clearance. In recent years, it has become increasingly common for a ball-and-socket fan to be designed such that the canopy (ceiling cover piece) can optionally be screwed directly into the top of the motor housing; then the whole fan can be secured directly onto the ceiling mounting bracket. This is often referred to as a dual-mount or tri-mount. Thank You for watching
