Sanwei Y2 – electric motor range: Chinese standard-motor scheme, frame sizes 80 to 160, 0.75 to 15 kW, exclusively two-pole, 415 V, no High Efficiency classification
The Y2 designation marks, in China, the widely used range name for standardised three-phase asynchronous motors following the pattern of the second generation of standard motors, carried in parallel by numerous Chinese makers; Sanwei is one of the suppliers building Y2 motors to this scheme and registering them in the Australian energy-efficiency register (GEMS/MEPS). The type codes, such as Y2 100L1-2 or Y2 80M2-2, follow the pattern of frame size, construction length (S/M/L), a variant digit and pole count.

The register lists here 10 versions with 0.75 to 15 kW, exclusively two-pole, at 415 V. Full-load efficiencies range from 80.8 to 91.5%, and at 75% load from 79.5 to 92.2%. Frame sizes run from 80 to 160, protection is almost exclusively IP55, and the mounting form covers practically the whole standard spectrum with B3, B5, B14 and B34. Manufacturing is exclusively in China, testing followed AS/NZS 1359.5:2004 with test method A; none of the ten motors carries a documented High Efficiency classification.
Y2 motors such as Sanwei's form the low-cost base offering in the low to mid power segment for pumps, fans and simple conveying tasks, competing with numerous other Chinese makers serving the same standard scheme.
When buying used, bearing condition and a checked insulation resistance of the winding, the visible condition of the terminal box and fan cover, the condition of shaft and key, and a legible nameplate with frame size and pole count matter; on standard motors with no documented efficiency class, it is worth checking actual energy consumption in operation before buying. Spares run through the general motor trade.

The Sanwei Y2 80M2-2 delivers 1.1 kW.
What to check before buying
- Match the data plate against the order: frame size, mounting and rating have to agree.
- Check the ingress rating against the installation site — outdoors or in dust the demands differ.
- Hold the mounting form and dimensions against the existing seat before ordering.
- The pole count sets the speed — when replacing an older unit, compare this first.
- For used units, ask about winding condition and bearing play.
- Ask about parts availability for this series — the running costs hang on it.
