Crompton Greaves Electric Motors – The Great Contributor to Industrial Growth
Every industry follows a different manufacturing process; therefore, the need for electric motors also varies a lot. As being the largest electric motors manufacturer in India, Crompton Greaves offers perfect fit application-oriented drives. The continuous R&D is expanding the electric motors categories to facilitate the end users have what they need to get peak efficiency. The recently updated CG electric motor categories are-
TEFC Electric Motors: These are Crompton Greaves low voltage motors available in aluminum and cast iron constructions. These are available in 0.18 kW to 350 kW capacity with 63 to 355 frames. These are designed with Class ‘F’ insulation to work at peak efficiency in 50 C / 70 C ambient temperature. Fan cooled TEFC induction motors are available up to 3000 KW. The category of Crompton Greaves TEFC electric motors can be explored based on application types like- farm duty motors, rock crusher motors, oil well pump motors, severe duty motors, pool pump motors, fractional horse power motors, etc.
Increased Safety Motors EX ‘E’ Non-Sparking Motors EX ‘N’: These CG electric motors are finding increasing applications in hazardous areas like in chemical industries, mines, petrochemical refineries etc having Zone II areas. Motors under Ex ‘n’ category provide reliable protection against the possibility of auto-ignition of vapors/ gases present in surrounding atmosphere. Non-sparking ex ‘n’ (LV) CG electric motors, designed as per IEC and IS standards, are available in 0.37 kW to 360 kW capacity. Non sparking ex ‘n’ (HV) electric motors are available in 180 kW to 12000 kW capacity.
Flame Proof Motors For Hazardous Areas EX ‘D’: Crompton Greaves has the largest manufacturing range of flame-proof motors. These are the best choice for hazardous zones like Class1 Div 1 and 2 or Zone1 and Zone 2. These electric motors are available in squirrel cage and slip ring configurations. Flame proof (LV) class motors are available in 0.37 kW to 355 kW capacities. Flameproof motors withstand the pressure developed by an internal explosion without letting any damage outside.
Energy Efficient Motors EFF I / IE2 / IE3: These electric motors are used primarily for reducing the production cost because of their low operational cost. These are 2-6 percent more efficient than their counterparts are. CG Determines electric motors efficiency according to clause 8.2.2.5.1 of IEC 60034-2-1. Designed as per IEC, IS & NEMA standards, IE2 range of motors is available for 0.37kW to 250 kW capacity. Apex IE2 series of electric motors is a green solution by CG for energy saving. IE3 class electric motors are engineered to deliver premium efficiency.
