Simo lists the YLF-100L1-4 as a three-phase induction motor. The rated output is 2.2 kW. The motor is four-pole, which at 50 Hz gives a synchronous speed of 1,500 rpm. The rated voltage is 400 V. The housing is frame size 100 L in foot-mounted form. The protection class is IP55. The efficiency is 86.8 per cent at full load, 86.8 per cent at 75 per cent load and 85.1 per cent at half load. The mounting arrangement to IEC 60034-7 is B3. The motor is built in China. The values are recorded in the Australian MEPS registration under the GEMS Determination 2012; measured to IEC 60034-2-1 (Edition 2.0). Rated output within this group ranges from 0.18 to 1,119 kW; the YLF-100L1-4 sits at the bottom of that range with 2.2 kW. Its immediate neighbours are the M3BP 112MJ 6L below it with 2 kW and the 864 above it with 2.43 kW. 3 Simo models across 2 series are on record.

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.

Frequently asked questions

How much power does the Simo YLF-100L1-4 have?

The Simo YLF-100L1-4 delivers 2.2 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.
