Cemp announces its High Efficiency motors - IE2 Cemp srl
IE1= Standard efficiency
IE2= High efficiency
IE3= Premium efficiency
The level of efficiency and the IE class needs to be engraved on the plate and written in the product documentation. The new Standards concern the electric motors with the following characteristics:
• Induction motor; Three-phase; Squirrel cage; Single speed
• Power supply up to 1000 V
• Rated output from 0.75 to 375 kW
• 2, 4 and 6 pole
• Duty type S1
• Frequency: 50 or 60 Hz
Instead, this Directive does not apply to some types of motors including two-speed motors, motors for hazardous areas (ATEX) and brake motors. Nevertheless, in view of saving energy and thereby reducing costs and CO2 emissions, Cemp decided to update his motors (Ex-d, Ex-de, Ex-nA) to the new Standards and EC Directive.
Series AB, AC, AN - EI2 motors additional features
