Abb clAims world first with liquid-cooled ie5 synrm motor thAt sets benchmArk for energy efficiency And power output
ABB has launched a new version of its IE5 SynRM (synchronous reluctance motor) series that combines the benefits of ultra-premium energy efficiency with highly effective liquid cooling. Said by the company to be a world first, this new design sets a benchmark for high power output and reliability in a compact footprint. Stefan Floeck, division president
IEC Low Voltage Motors, ABB, commented: “ABB pioneered both SynRM technology and liquid cooling for induction motors. Now we have brought them together in our IE5 SynRM Liquid-cooled motor that enables customers to enjoy the benefits of ultra-premium efficiency in an even wider range of applications. It is yet another world- first for this series following the launch of our IE5 SynRM Increased Safety motor for hazardous areas.” IE5 SynRM Liquid-cooled motors
are suited to a wide range of industries including marine propulsion, rubber and plastics production, and food and beverage. Energy efficiency is crucial
to 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% of a motor’s TCO, with the purchase cost accounting for about 2%. IE5 motors have 40% 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 effective 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. They also do not need fans or ventilation, so they do not disturb the surrounding air or release heat into the local environment. The high power output of the liquid-
cooled IE5 SynRM offers increased design flexibility. 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. IE5 SynRM Liquid-cooled motors are
available in frame sizes IEC 200-315 in aluminium frames, with steel available on request. The versatile
design enables the motors to provide exceptional performance over a range of powers from 37 to 710kW at 400V.
