W23 SYNC+ ULTRA IE6 EFFICIENCY MOTOR
WEG INTRODUCES
In response to the evolving energy efficiency landscape and the increasing demand for environmental responsibility, global motor manufacturer WEG has launched its new W23 Sync+ ULTRA motor. Having released the W23 Sync+ general line in November 2023, the
new ULTRA variety boasts IE6 efficiency – going one step further than its predecessor that is available in efficiency ratings up to IE5
T
he W23 Sync+ ULTRA combines permanent magnet (PM), ferrite or neodymium magnets, and synchronous reluctance
(SynRM) motor technologies to deliver unparalleled efficiency across all speeds. The key to the W23 Sync+ ULTRA motor’s exceptional efficiency lies in this PMSynRM technology, which effectively reduces electrical losses through the strategic use of magnets. This results in a motor that maintains high efficiency levels even under varying speed and load conditions. Compared to conventional induction motors, the W23 Sync+ ULTRA experiences minimal efficiency loss, demonstrating a decrease of less than two per cent when load and speed are reduced by 25%.
A MILESTONE IN MOTOR TECHNOLOGY Designed to surpass current European Ecodesign regulations, the new flagship IE6 model reinforces the transformative benefits of the new PMSynRM technology, emphasising its ability to exceed ultra-premium efficiency levels while reducing environmental impact. The motor will be available in a range of
frame sizes from IEC 80 to 450 (NEMA 140 up to 7000). Able to operate over a wide speed range at constant torque, without the use of forced ventilation, it is available in speed ranges from 750 up to 6000 revolutions per minute (rpm). The motor’s output rating ranges from 0.75 to 1250 kW, while it is compatible with a 220/380 volt (V), 230/400 V, 240/415 V or 400/690 V power supply. “The W23 Sync+ ULTRA IE6 efficiency motor
represents a significant milestone in motor technology,” explained Marek Lukaszczyk, European and Middle East marketing manager at WEG. “An IE6 motor has another 20 per cent reduction of losses compared to an IE5 motor. The W23 Sync+ ULTRA’s hybrid design not only ensures higher efficiency across all speeds, but
also contributes to reduced CO2 emissions, prolonged operational lifespan and decreased maintenance requirements, aligning perfectly with the growing global commitment to sustainability.
38 DESIGN SOLUTIONS JUNE 2024
“As traditional induction motor technology
nears its maximum efficiency capabilities, the necessity for alternative solutions became increasingly evident to WEG. Attaining higher efficiency standards requires electric motors to accommodate exceedingly high levels of inrush current, thereby requiring the implementation of new starter mechanisms and protective systems when replacing older motors.” The environmental impact of the W23 Sync+
ULTRA extends beyond energy savings, contributing to broader reductions in greenhouse gas emissions and aligning with sustainable practices. The motor’s energy efficiency directly translates to reduced demand for natural resources and minimised environmental impacts,
making it an ideal choice for industries striving for efficiency, reliability and sustainability. The W23 Sync+ ULTRA motor line is available
globally, supported by WEG’s comprehensive technical support and services. Its compact design and compatibility with existing installations make it an ideal choice for a wide range of applications, from compressors and pumps to fans and conveyors.
