Simo – other models: the collective page of MEPS-registered YLF three-phase motors outside the named ranges, frame sizes 100 to 250, 2.2 to 55 kW, two- and four-pole
This page gathers the Simo three-phase motors the Australian energy-efficiency register could not assign to a named range. The designations recorded in the register, YLF-100L1-4 and YLF2-250M-2, follow a scheme of the YLF or YLF2 range code, the IEC frame size (100, 250), the build length and the pole count at the end (4, 2).

The register lists here 2 versions with 2.2 to 55 kW rated output, two- or four-pole, for a 400 V supply, with full-load efficiencies from 86.85 to 94.31% and at 75% load from 86.85 to 94.02%. Protection ranges from IP54 to IP55, frame sizes from 100 to 250, the mounting code is B3 (foot type). Manufacturing takes place in China, testing followed the 2012 GEMS determination with test method B.
The wide span from 2.2 to 55 kW shows the page gathers both small standard motors and considerably larger industrial motors; two-pole versions run at 3,000 rpm at 50 Hz, four-pole at 1,500 rpm, with both speed classes ranking among the standard drives for pumps, compressors and fans in industry.
When buying used, bearing condition and a checked insulation resistance of the winding, the condition of the terminal box and fan cover, the condition of shaft and key, and a legible nameplate with frame size, pole count and protection rating matter; on the larger 250 frame size, checking bearing play under load is also worthwhile. Spares run through Simo's distribution.
