The Bjem GX 802-2 comes from the GX series. The rated output is 1.1 kW. The motor is two-pole, which at 50 Hz gives a synchronous speed of 3,000 rpm. The rated voltage is 400 V. The housing is frame size 80 M in foot-mounted form. The protection class is IP55 and IP56. The efficiency is 84 per cent at full load, 84.8 per cent at 75 per cent load and 83.4 per cent at half load. The motor weighs 20 kg. At full load it delivers 3.68 Nm. Mounting arrangements to IEC 60034-7: B3, B5, B35 and V1. The motor is built in China. The data is based on the Australian MEPS registration under standard AS/NZS 1359.5:2004; measured to AS 1359.102.1:1997. The GX series covers 85 models. Rated output within it ranges from 0.75 to 160 kW; the GX 802-2 sits at the bottom of that range with 1.1 kW. Its immediate neighbours are the GX 90S-6 below it with 0.75 kW and the GX 100L-6 above it with 1.5 kW. 85 Bjem models are on record.

BJEM GX – the range of MEPS-registered three-phase motors, frame sizes 80 to 315, 0.75 to 160 kW, 2- to 8-pole, 400 V, IP55/IP56 throughout

The GX range from supplier BJEM is carried in the Australian energy-efficiency register (GEMS/MEPS) as a standalone motor range. The type designation consistently follows the scheme GX followed by the IEC frame size, a foot-form letter and pole count, e.g. GX 100L-2 or GX 132M-4K; the additional letter K on individual types sets those versions apart from the rest of the range.

The register lists 85 versions in this range with 0.75 to 160 kW, two- to eight-pole, all rated for 400 V. Full-load efficiencies run between 73.6 and 96.05%, and at 75% load between 75.9 and 95.92%. All 85 motors are built to the combined protection rating IP55/IP56, frame sizes run from 80 to 315 under IEC, manufactured consistently in China and tested under AS/NZS 1359.5:2004 with test method B. For 4 of the 85 motors the High Efficiency Level 2005 is documented, the remaining 81 reach no classification. The mounting code is consistently the combination B3/B5/B35/V1.

With its consistent type logic and uniform execution in protection rating and voltage, GX presents as a closed catalogue programme in the mid to upper power range, used in industry and trade for pumps, fans, conveyors and compressors.

When buying used or replacing, what matters is bearing condition and a checked insulation resistance of the winding, visible overheating marks on the terminal box and fan cover, the condition of shaft and key, and a legible nameplate with frame size, pole count and efficiency class; for the few motors carrying High Efficiency Level 2005 it is worth checking the nameplate against the actual classification. Spares depend on the distribution channel through which the motor was sourced.

Frequently asked questions

How much power does the Bjem GX 802-2 have?

The Bjem GX 802-2 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.
