Combines PM and SynRM technologies

The permanent magnet synchronous reluctance motor (PMSynRM) line is suitable for applications including compressors, pumps, fans, blowers, conveyors and more. Advantages of the W23 Sync+ motor line include a higher level of efficiency for the entire speed range compared with conventional induction motors, and a higher power factor than synchronous reluctance motors. This results in a lower total cost of ownership (TCO) for plant managers.

“We’re looking to the future with the W23 Sync+,” explained Marek Lukaszczyk, European and Middle East marketing manager at WEG. "The IE5 and IE6 models far surpass the current European Ecodesign regulation, which are currently required to meet IE3 or IE4 standard. Available in IE5 and IE6 efficiency ratings, WEG offers the largest range of motors meeting IE5 and IE6 efficiency levels on the market.”

The W23 Sync+ is available in frame sizes from IEC 80 to 450 (NEMA 140 to 7000). Able to operate over a wide speed range at constant torque, without the use of forced ventilation, this multi-platform solution is available inspeed ranges from 750 up to 6000rpm. The motor’s output rating ranges from 0.75 to 1250kW, while it’s compatible with 220/380V, 230/400 V, 240/415V and 400/690V power supplies.

Efficiency gains

The W23 Sync+ motor line unlocks energy savings that directly impact on facilities’ CO2 reductions. In fact, the WEG team has calculated that replacing an IE3 induction 75kW 4 pole with an IE6 W23 Sync+ motor variety, may result in a reduction of 126 tons of CO₂ during its expected lifetime of 25 years. Taking into account an operation time of 6500h per year.

In addition, while a conventional induction motor loses over 20 per cent efficiency across its varying speed and load ranges, the W23 Sync+ maintains its higher efficiency decreasing less than.2 per cent when the load and speed are reduced for 25%.

Another key advantage of the W23 Sync+ is its compact nature with the same power per frame ratio as induction motors. For example, the IE5 variety is available in the same frame size as an IE3 motor, which makes interchangeability with existing installations smooth and hassle free.

WEG invested over €122 million in R&D in 2022. During the development phase for the W23 Sync+, WEG’s R&D team wanted to ensure its customers could benefit from the best technical characteristics of both PM and SynRM motor technologies, including ferrite and neodymium magnets possibilities.

“WEG strives to increase efficiency, reduce costs, improve quality and reduce the raw materials used in products,” continued Lukaszczyk. “The ferrite magnet used in the W23 Sync+ is constructed from a ceramic material and has a local supplier and producer. This avoids global supply chain issues and results in material price stability.”
