Jlem Other models

The register lists here 5 versions with 5.5 to 160 kW rated output, two- to four-pole, at voltages from 400 to 415 V. Full-load efficiency ranges from 88.9 to 95.7%, and at 75% load from 88.7 to 95.8%. Protection is IP55 on four motors and IP45 on one; frame sizes run from 132 to 315. Testing mostly followed the 2012 GEMS determination and, for one version, the 2019 determination, with test method B or 2-1-1B; four of the five versions are assessed for High Efficiency classification and none reaches a High Efficiency Level. The mounting form is B3 on four motors, extended with B35 and V18 on one.

With a span from 5.5 to 160 kW, the range covers both smaller standard motors and larger versions for pumps, fans, compressors and conveying plant in industry; the mostly two-pole design of the smaller frame sizes points to high-speed applications.

When buying used, bearing condition and a checked insulation resistance of the winding, the condition of shaft and key, visible corrosion on the terminal box and fan cover, and a legible nameplate with frame size, pole count and voltage matter; on the IP45 version, use in dusty or damp environments should be checked beforehand. Spares run through the relevant JLEM distribution.
