For the raw and cement ball-mill twin drives Slip Ring or other wound type rotor motors are used all over the world. CG Hungary is the first in the world to successfully break this tradition with double Squirrel Cage motors supplied to Duna-Dráva Cement Company at Beremend.

This new solution is significantly cheaper from the investment view compared to the traditional solutions.

On one hand the double-cage motor is substantially cheaper than the Slip Ring motor, On the other hand the costly starting equipment and the adherent short-circuiting switch together with the controller are not required. The usage of our solution due to the low operational and maintenance costs further increase the adaptability of this new equipment.

One of the special areas of focus for CG has been motors for hazardous area applications. The scenario of operation of these motors and the regulatory requirements are both complex. They are also constantly changing with the introduction of new European and Indian standards. We keep abreast with the latest developments to ensure that all the products fully comply with relevant regulations.


Flameproof Induction Motors
(Ex 'd' for ZONE-I, II - Gas Group IIA, IIB)

The essential principle of electrical apparatus with flame proof enclosure is that the hazardous atmosphere is not excluded from entry into the enclosure. It is recognized that an explosion is likely to occur within the apparatus but the construction of the enclosure should be such that it shall withstand the internal explosion without any evidence of distress and shall prevent the communication of the internal ignition to the surrounding atmosphere (the term flame proof as used here is synonymous with the term "explosion proof" as used in the USA or "Explosion Proof type 'd' protection" used in Germany and other continental countries)


Construction

Stator frame has a barrel type construction made from thick fabricated steel to withstand internal pressure. Stringent checks like pressure tests are in place to ensure to high degree of welding quality. Adequate care is taken during machining to ensure a perfect concentricity of stator bore leading to minimum vibration level and optimum heat transfer. For higher frame sizes, i.e. 630 & 710 the frame is of TETV construction. The tubes are double expanded in thick end plates to provide protection against leakage in case of explosion.
