ABB has achieved another world rst for its IE5 SynRM (synchronous reluctance motor) series with the launch of a new version that combines the bene ts of ultra-premium energy eciency with highly eective liquid cooling. The new design sets a new benchmark for high power output and reliability in a compact footprint. Customers can use IE5 SynRM Liquid-cooled motors to save energy costs and cut emissions in new projects or as a drop-in replacement for less ecient motors. They are ideally suited to a wide range of industries including marine propulsion, rubber and plastics production, and food and beverage. A major advantage of the IE5 SynRM Liquidcooled motors is that they are much more ecient than the traditional liquid-cooled induction motors in current use and could oer signi cant potential for upgrading with energysaving technology. Energy eciency is crucial in optimising the total cost of ownership (TCO) of an electric motor because the cost of the energy to run it throughout its life accounts for around 97 percent of a motor’s TCO, with the purchase cost accounting for about two percent. IE5 motors have 40 percent lower energy losses than commonly used IE3 motors. This makes the payback time for selecting an IE5 instead of an IE3 motor often less than one year. Reliability is improved by highly eective cooling combined with the cool SynRM rotor and cooling ribs on the bearing assembly that reduces the operating temperature of the bearings. This helps to increase the lifetime of this key component and reduce maintenance needs. The motors are robust, with tight seals to keep out moisture, dirt and dust, and a smooth outer surface to prevent dust build-up. This makes them perfect for demanding applications that require high power density where space is restricted such as marine propulsion systems and thrusters. Furthermore, the motors do not need fans or ventilation, so they do not disturb the surrounding air or release heat into the local environment. This is a major bene t in processes that are impacted by airow, such as rubber and plastics production, and food and beverage applications like chocolate conche machines. With no fans, the motors also enhance the working environment by reducing noise levels. The high power output of the liquid-cooled IE5 SynRM oers increased design exibility. It can enable a machine to be upgraded to deliver a higher power output within the same footprint, or it can allow for a more compact installation footprint while still providing the same output. The IE5 SynRM Liquid-cooled motors are signi cantly lighter than competing designs, making them easy to handle and install. A 250 kW IE5 SynRM motor in frame size 315 weighs 870 kg, this is almost half the weight of a corresponding IE3 induction motor. IE5 SynRM Liquid-cooled motors are available in frame sizes IEC 200-315 in aluminum frames, with steel available on request. The versatile design enables the motors to provide exceptional performance over a range of powers from 37 to 710 kW at 400 V.
