Vacuum Cleaner β€” Function β€” Principle β€” Main components β€” features β€” types - working β€” accessories - Filters β€” Repairing. Resistivity is the inverse of conductivity. Coil details β€” shapes of slot β€” slot insulation β€” coil formation β€” Stator stationary winding β€” Rotor rotating winding β€” DC Armature winding - Lap winding β€” wave winding β€” whole coil winding β€” half coil winding β€” concentrated winding β€” distributed winding - single layer winding β€” double layer winding β€” single phase winding β€” three phase winding β€” concentric winding β€”. Vacuum cleaner and Washing machines. Electrical Cooking Appliances. Maintenance of Transformers. Should have no deteriorating effect on the material, in contact with it. Single phase windings β€” Lap winding β€” wave winding β€” concentric winding β€” Three phase winding β€” single layer winding β€” double layer winding. Page No. Should be resistant to thermal and chemical deterioration. Class B. Class E. Resistant to oils or liquids, gas fumes, acids and alkalies. Its value should be very high. Classification according to temperature : The insulating materials are classified mainly based on the thermal limit. Insulation materials of A and B class are being used for a long time for winding insulation purposes. If a reasonably long life of insulation is expected, its operating temperature must be maintained low. Classification according to substances and materials. Non-inflammable when exposed to arcing. Thus the insulating materials are grouped into different classes Y, A, B, and C with temperature limits of 90 0 C, 0 C and 0 C for the first three classes and no specific limit. Sec School Parava kottai - Thiruvarur District. Grade Municipal Boys Hr. This is evident when we touch an electric machine when it is under operation. Winding Insulating Materials. Electric mixer and Egg Beaters. The higher the temperature, the higher will be the rate of its chemical degrading, and hence the lower will be its useful life as shown in fig. Electric Fan and Electric hair drier. Grade Govt. Therefore, it is necessary to determine the limits of temperature for the insulation, which will ensure safe operation over its expected life. Electrical insulation and dielectric materials includes various forms of materials that surround and protect electrical conductors and prevent unwanted current flow, leakage. With the existence of newer insulating materials, namely, the plastics and silicones, during the middle of this century, a need was felt to reorganize the classification of the insulating materials. Breakdown of insulation results in short circuiting of the coils, causing electric currents to flow in unintended paths. In the above classification Non-impregnated, moisture absorbing materials of Y- class are not generally used for motor winding insulation purposes. Dielectric Strength : Dielectric strength is the maximum voltage gradient that the material can withstand before electrical breakdown occurs. Class F. Details of winding. Washing Machine β€” Function β€” Types β€” Semi and Fully Automatic β€” Top and Front loading β€” washing technique β€” working cycle β€” construction and working of washing machine β€” comparison of Top and front loading machines β€” Problems and Remedies. Rewinding and Testing of Electric Motors. The Electrical insulating materials are defined as materials which offer a very large resistance to flow of current, and for that reason they are used to keep the current in its proper path along the conductor. Electrical specifications include electrical resistivity, dielectric strength, and dielectric constant. Assistant P rofessor Senior Grade Dept. Maintenance of Roatating machines. Vacuum Cleaner and washing machine. Mica, fiberglass alkali free alumino borosilicate , bituminized asbestos,. High thermal strength. Class Y and A cover the various organic materials without and with impregnation respectively, while classes B and C cover inorganic materials, respectively with and without a binder. This book has been prepared by the Directorate of School Education on behalf of the Government of Tamilnadu. Since they easily absorb moisture, their quality quickly degrades. Introduction β€” Constructional features β€” working β€” friction lead β€” static suction head β€” static delivery lead β€”automatic operation of pump β€” Trouble shooting. Class Y. Maintenance of Transformers :. Centrifugal Pump. Introduction β€” Action taken for rise in oil temperatures and falling of oil level β€” methods of drying. Sampath Nagarajan. In recent times F and H class are being increasingly used for winding insulation. Development of winding β€” AC machines. Sec School Pollachi - Coimbatore District.

This may also cause, electric shocks to humans operating the machinery and also damage the machines. Introduction β€” Electrical properties β€” Classification β€” Characteristics β€” Application areas insulation materials β€” plastics β€” insulating varnishes - Types of Insulating varnishes. Solid Insulating Materials [Inorganic and organic]. Requirements of a good insulating materials involve physical properties, reliability, cost, availability, adaptability to machining operations etc. C-class materials are generally brittle, so they too are not suited for motors. Winding Wire. Dry air, carbon dioxide, argon, nitrogen, etc. Rewinding and Testing of Electric motors.
