ABB launches IE5 motor for explosive environments

ABB has added an IE5 SynRM Increased Safety motor to its award-winning IE5 SynRM (synchronous reluctance motor) series for use in potentially explosive atmospheres.

Customers operating in hazardous area industries can now ensure safety and boost their energy efficiency by deploying motors that offer up to 40% lower energy losses compared to commonly used IE3 motors.

The new motor offers accurate control and high efficiency throughout the whole speed range, even at partial loads. This makes it an upgrade choice for standard induction motors in pumps, fans and compressors for industries where explosive gas, vapor or dust might be present, such as oil and gas, chemicals, wood processing and flour milling.

A key benefit of IE5 SynRM Increased Safety motors is that they run cooler than standard designs. Bearing temperatures are reduced by up to 15°C and winding temperatures by up to 30°C. This provides increased reliability, prolongs the motor’s lifetime and reduces maintenance needs.

Stefan Floeck, Division President IEC Low Voltage Motors, ABB, said: “We have achieved a significant world-first by bringing the benefits of IE5 ultra-premium efficiency to the hazardous area sector.”

To ensure an environmentally friendly design, the motors don’t contain magnets or rare earth metals.

IE5 SynRM Increased Safety motors are available with output power of 5.5 to 315 kilowatt (kW) in frame sizes IEC 132-315.
