Sakor Technologies Inc. has developed a series of dynamometer systems for customers required to test and verify the level of efficiency of electric motors in accordance with a variety of national and international standards, including IEC 60034-2-1; IEEE 112B; and Canadian standard C390-93. The units can be used to test from two to eight pole motors ranging from 10 watts to over 3 megawatts.

As part of the global effort to reduce the use of fossil fuels and greenhouse gas emissions, regulators are developing energy efficiency standards for the billions of electric motors used around the world. These regulations specify how to ensure motors are meeting efficiency standards that are either already into effect or are yet to be phased in. First to be regulated will be induction motors, with permanent magnet motors likely to be regulated in the coming years, followed by inverter driven motors.

The new line of motor testing dynamometers provides high-accuracy testing for designers and manufacturers of all sizes of electric motors, for use in applications such as large industrial equipment or consumer appliances such as fans or washing machines. They have been optimized so that individual machines can test the widest range of motor sizes while still maintaining accuracy tolerances. Sakor systems

“We have worked hard to define this line of systems to give the maximum utility per machine and make it most cost-effective for the customer,” said Randal Beattie, president of Sakor. “By optimizing equipment to test the widest range of motor sizes with one system while staying within required accuracy levels, customers will need to buy the fewest number of machines at the lowest total cost.”


Sakor systems meet the standards’ tolerances and requirements for data precision and accuracy. Able to precisely measuring motor efficiency, these dynamometers “provide an essential tool to engineers seeking to reduce fossil fuel consumption and enhance energy efficiency to meet strict environmental standards and regulations.”
