Rotor Motors
Rotor UK and Beatson Fans & Motors have been friends in business across generations.
Originally known as Exico (Export/Import Company) Rotor UK have proved to be one of the strongest names in the Electric motor industry.
Rotor Uk are about quality and service in an ever demanding environment!! Top quality motors at fantastic prices, backed up by a wealth of expertise and knowledge!!
Beatson Fans and Motors are proud to be part of the Rotor UK distributor network.
The new efficiency classes have a new nomenclature:
IE1: Standard Efficiency
IE2: High Efficiency
IE3: Premium Efficiency
IE Stands for International Efficiency
IEC 60034-30 (Rotating Electrical Machines Part 30: Efficiency classes of Single-Speed, Three-Phase, Cage Induction Motors) has been drawn up to provide a unified standard worldwide. This classified low-voltage induction motors in new efficiency classes (Valid from October 2008). The efficiencies as per IEC 60034-30 are based on measuring losses to IEC 60034-2-1.
The additional losses now need to be measured as they can no longer be added as a fixed percentage.
The new EuP Directive
Will forbid placing IE1 motors on the market by 2011
Will allow placing only IE3 large size motors on the market after 2015
Will allow placing only IE3 motors (all sizes) on the market after 2017
It will be possible to install IE2 motors after 2015 but inly if they are operated through frequency inverters.
New Testing Methods
With the new testing methods the additional losses can no longer be assumed as fixed percentage values (0.5%) but need to be determined by carrying out the appropriate measurements to IEC 60034-2-1: 2007. For this reason the nominal efficiencies will ofter decrease from EFF1 to IE2 and from EFF2 to IE1 although no techincal or physical changes have been implemented on the motors.
Previously: PLL = 0.5% of P was added
Newly: PLL = individual measurements (PLL = Load-dependent additional losses)
Probable exclusion from EuP Directive: Explosion-proof motors according to ATEX, brake motors, smoke extraction motors.
Probable implementation on 16.06.2011: IE2 minimum efficiency for motors from 0.75kW – 375 kW
Probable implementation on 01.01.2015: IE3 minimum efficiency for motors from 7.5 kW – 375 kW and/or combination of IE2 motors and frequency inverters
Probable implementation date 01.01.2017: IE3 minimum efficiency for all motors from 0.75 kW – 375 kW and/or combination of IE2 motors and frequency inverters.
