The power usage of motors used in machinery is said to make up 40-50% of the world’s electricity consumption, making these industry-essential devices a key energy reduction target.

The latest inverter motors are also contributing to lower power consumption as they adjust their rotational speed according to operating conditions. Furthermore, demand is ramping up for new-generation servo motors, which typically find use in industrial robots as they can rotate forwards and backwards for accurate positioning. These three motor types (high-efficiency,
