W23 Sync+ is WEG's new generation of inverter-driven synchronous motors. The magnets in the rotor create their own magnetic field without induced currents, so rotor losses are largely eliminated. The line reaches IE5, the highest level defined in IEC TS 60034-30-2:2016, cutting losses by around 40% compared with IE3.
Efficiency stays high regardless of speed or load, saving up to 30% of energy compared with induction motors on frequency inverters. Because it delivers constant torque across a wide speed range without an external blower, it suits applications that need variable speed with constant torque. With the same power-per-frame ratio as IE3 induction motors, it is easy to retrofit in existing plants.
For projects that demand even more, the W23 Sync+ Ultra version goes beyond IE5 towards the IE6 level. Euronorm supports the selection of W23 Sync+ motors together with a suitable WEG drive and provides quotations.
Features
IE5 efficiency
It reaches the top level defined in IEC TS 60034-30-2, with around 40% lower losses than IE3.
