Using accurate torque measurement for building ultra-high-performance motors - Case Study

Background
An ever-growing demand for electric vehicles, coupled with 65% of the electrical energy used in the industry consumed by electric motors, pressured the governments around the world to introduce MEPS (Minimum Energy Performance Standards), setting mandatory minimum efficiency levels for electric motors.

In response, motor designers are looking to reduce losses in their machines to boost efficiency and thus limit CO2 emissions through developing high-performance electric motors of high energy efficiency and low weight.

When it comes to assessing the performance of motors, measuring torque, speed, and calculating the power quality characteristics are of utmost importance. These measurements can not only give a direct insight into the performance and health of the motor, they can ensure reliable operation over time, predict failures and help minimise downtime.
