CEILING FAN OBJECTIVE : To study the working, construction And troubleshooting of Ceiling Fan
2. INTRODUCTION A ceiling fan is a device suspended from the ceiling of a room, which employs hub- mounted rotating paddles to circulate air. First electrically powered fan was invented in 1882 by Philip Diehl. Crompton Greaves Ltd is the leading manufacturer of fans.
3. PRINCIPLE If a current carrying conductor is placed in a magnetic field it experience a force and start to rotate. The direction of rotation can be found by Fleming s Left Hand R ....etc

working principle of hydraulic excavator ppt

Excavators are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the house.The house sits atop an undercarriage with tracks or wheels. They are a natural progression from the steam shovels and often mistakenly called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors.Due to the linear actuation of hydraulic cylinders, ....etc

ppt working principle of pulse tube refrigerator

Abstract

The working fluid for the pulse tube refrigerator is Helium, which is non-toxic to humans and harmless to the environment. The Pulse Tube Refrigeration unit offers a viable alternative to units that currently require CFC and HCFC working fluids. Pulse Tube Refrigerators can be operated over wide range of temperatures. These units can be used in numerous space and commercial applications, including food freezers freeze dryers. It can also be used to cool detectors and electronic devices ....etc

The WEG tachogenerators have been designed for applications
on servocontrol operating machines, driving of textile
machines, accelerators, braking of elevators, control and regulation
of fine adjustments which depend on speed variation
and other applications that require continuous and closely
controlled speed.
The tachogenerator gives a continuous voltage sign corresponding
to the speed actual value of the electric machine to
which it is coupled.
1.2.CONSTRUCTION
The Tachogenerator is fitted with permanent magnets in
the stator with ....etc
