The MS90S-2 from Mechtric is a three-phase induction motor. The rated output is 1.5 kW. The motor is two-pole, which at 50 Hz gives a synchronous speed of 3,000 rpm. The rated voltage is 415 V. The housing is frame size 90 S in foot-mounted form. The protection class is IP55. The efficiency is 78.5 per cent at full load, 77 per cent at 75 per cent load and 70 per cent at half load. The motor weighs 12 kg. At full load it delivers 5 Nm. The motor is built in China. The values are recorded in the Australian MEPS registration under standard AS/NZS 1359.5:2000 (Legacy); measured to AS/NZS 1359.102.3:2000. Rated output across the Mechtric range ranges from 0.75 to 132 kW; the MS90S-2 sits at the bottom of that range with 1.5 kW. Its immediate neighbours are the Y2-90S-4 below it with 1.1 kW and the JL3 100L1-4 above it with 2.2 kW. 98 Mechtric models are on record. The model is listed under Electric motors. 24 verified figures from 1 source are on file.

Mechtric – other models: the collective page of MEPS-registered three-phase motors outside the named ranges, frame sizes 80 to 315, 0.75 to 132 kW, 2- to 8-pole, 415 V

This page gathers the three-phase motors carried in the Australian energy-efficiency register under the Mechtric brand, which the register does not assign to a named range. No reliable information is available on Mechtric's headquarters or group ownership. The model list shows two parallel designation schemes: the MS code with frame size and pole count (e.g. MS100L-2) and the WE code (e.g. WE132M-4), which could indicate two parallel product lines or designations taken over from a supplier; nothing further can be established from the dump.

The register lists here 93 versions with 0.75 to 132 kW, two- to eight-pole, all rated for 415 V. Full-load efficiencies run between 68.4 and 95.79%, and at 75% load between 60.9 and 95.74% — a comparatively wide range spanning small eight-pole units up to large two-pole ones. All 93 motors are built to protection rating IP55, frame sizes run from 80 to 315 under IEC, manufactured consistently in China. Testing followed mostly the older 2000 Legacy standard, a smaller share the 2012 GEMS determinations, with test method A. None of the 93 motors is classified under the Australian High Efficiency Level. Mounting codes range from a broad combination of foot and flange forms to the vertical forms V1 to V19.

The page thus covers a broad IEC standard-motor programme without particular efficiency certification, of the kind common in the spares and retrofit trade for older industrial plant; the wide spread of pole counts and frame sizes points to a full-line catalogue programme.

When buying used, 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; since none of the motors carries a High Efficiency Level certification, for energy-intensive continuous duty it is worth comparing against IE2/IE3 alternatives. Spares depend on the distribution channel.

Frequently asked questions

How much power does the Mechtric MS90S-2 have?

The Mechtric MS90S-2 delivers 1.5 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.
