As the technology of motors, bearings, ventilation and design techniques continue to improve so will the efficiency of electric motors; Leroy Somer is determined to stay ahead in the race.

The International conferences of Kyoto and Buenos-Aires set targets for a world-wide reduction of 5.2% in CO2 levels by the year 2010 In 1995, the European Commission for energy began discussions with the manufacturers of electric motors

Always at the forefront of developments in motor technology, Leroy Somer has based its energy policy since the 1970's on two distinct axes.

First, renewable energy sources as demonstrated by a co-operation with Vestas, one of the world's leading manufacturers of wind generating systems, since 1996.

Second, by developing a range of high efficiency motors in the 1980's, with the development of motors specifically designed to work with inverters and with motors such as Varmeca with electronics built in.

Earlier this year, LS was at the forefront of discussions that led to the European Manufacturers Commission signing an agreement with the European Commission.

This will define efficiencies for 2 and 4 pole motors up to 90kW, promote high efficiency ranges and, as from January 2000, label all motors with their efficiency, either EFF3 for the lowest, EFF2 or EFF1 for the highest.

This will include all standard, single speed, 2 and 4 pole motors to IEC standards with IP54 or IP55 enclosures and a 230v or 400v, 50Hz supply.

Determined to stay at the forefront in this vital area, LS has decided that from January 2000, the EFF2 range of energy efficient motors will become the standard AC motor range.

It will also offer a range of high efficiency motors to EFF1.

EFF2 means that the efficiency of a standard LS 1.1kw motor will be in the order of 83% instead of 76% with the previous generation.

Similar figures for an 11kw motor will be 91%, a 3% increase on an already high figure.

As the technology of motors, bearings, ventilation and design techniques continue to improve so will the efficiency of electric motors.

Leroy Somer is determined to stay ahead in the race.

It is no coincidence that the colour of an LS standard motor is green.
