Manufactured with AEG Technology, they’re mainly designed for driving smoke extraction fans. These motors have squirrel-cage rotors for implementation so automatic smoke & heat extraction units to EN 12101-3. Mainly used in buildings in which smoke control is necessary due to their shape and arrangement, they are classified according to EN 12101-3 as below:

*F180 corresponds to 180C for 120 min
*F250 corresponds to 250C for 120 min
*F300 corresponds to 300C for 60 min
*F300 corresponds to 300C for 120 min

Havells Smoke Extraction Motor

Nipa Agencies are expert in havells smoke extraction motor in Ahmedabad Gujarat India. As there are continual developments in power electronics, the industry is focusing on devising drives for medium voltage motors with switching devices which can both turn on and off with rapid transitions to reduce switching losses. However, this is at the cost additionally stressing the motor insulation. The premature failure of motor insulation appears to be associated with accelerated degradation. we are expert in havells smoke extraction motors dealers.

so as to minimize insulation degradation. so havells smoke extraction motors dealers However, problems of premature failure of medium voltage rotating machines, when fed by inverters must be addressed immediately, as it can affect the motor manufacturers standing. Although different topics havells smoke extractions motorse in ahmedabad, related to the use of such power supplies have been investigated, the time has come to explore the physical mechanisms that are involved in the aging of insulating materials. best product of havells smoke extraction motors dealers.

Nipa Agencies are expert in havells smoke extraction motors dealers the main objective of this thesis is to provide a comprehensive understanding of the degradation processes of medium voltage form-wound stator havells smoke extractions motorse in Ahmedabad, havells smoke extractions motorse in Ahmedabad, within mica-based groundwall also turn-to-turn insulation, when they are exposed to various types of voltage waveforms. best quality of havells smoke extraction motors dealers.

we are expert in havells smoke extraction motors dealers To understand the design of a form-wound stator coil, various insulation systems are briefly described. The stator winding insulation system contains several components and features, which combined ensure the required electrical isolation exists. The basic stator insulation systems that will be discussed in the following three subsections are composed.

Nipa Agencies are expert havells smoke extractions motorse in Ahmedabad in Such corona-resistant enamels have been used since as turn insulation. The advantages are enhanced voltage endurance life, allowing reductions in the groundwall insulation thickness, and higher turn-to-turn surge withstands capability. so havells smoke extractions motorse in Ahmedabad, the behavior of corona-resistant enamels is critical in today’s variable speed drive applications so havells smoke extraction motors dealers in Gujarat

we are expert in havells smoke extraction motors dealers in gujaratThe main purpose of the groundwall insulation system is to separate the copper conductors from the stator core. Usually, groundwall insulation also triggers a ground fault relay. For a long service life, the groundwall must meet the rigors of electrical, so the mechanical stresses that it is subjected to. This class of insulation the additional stress relief coatings,

In this class of insulation, the material is fully processed and further impregnation or cure is needed when used for form-wound coil
and bar insulation. It can be applied as half-lapped tapes or as combination of tape and sheet. Slot pressing may be done to squeeze out the air between layers of the material andwhen the heat is applied, the varnish softens and becomes tacky and on cooling, a weak bond develops between the layers of tape. This method, developed in Europe, was named Haefley process. best quality of havells smoke extraction motors dealers.

we are expert in havells smoke extraction motors dealers This class of insulation the system consists of small mica flakes that are deposited on a glass fiber backing tape. Once the tape has been wrapped around on the conductors, the synthetic resin is cured at an elevated temperature and pressure. This technique offers the possibility of manufacturing nearly void-free insulation so can withstand high dielectric stress. This insulation system has been in use since the sixties.

In form-wound coils, it is not unusual include semi-conducting tape and filler materials in the slot portion. Such tape provides a good electrical contact the slot wall due to its low resistance. so havells smoke extraction motors dealers The filler materials protect the groundwall insulation from physical damage and fill the gap between the coil surface and the slot. To avoid shorting the stator core laminations, material with constant conductivity so havells smoke extraction motors dealers in gujarat.

quickly changing so as to provide higher voltages and faster switching devices with steeper wavefronts. The option of increasing the voltage rating is preferred over increasing the current rating because of the practical limitations of the power components: motors, cables, and transformers,

At this time, there is no predominant topology in medium voltage drives. Multilevel topologies (more than two-level) are preferred. The simplicity of three-level topology makes it one of the most common systems. In the present state-of-the-art, a two-level topology could represent the best option havells smoke extraction motors dealers in Gujarat, especially with the higher ratings of the currently available switches; the associate insulation problems discourage the motor manufacturers to adopt. so havells smoke extraction motors dealers in Gujarat.
