Kuo Shay AEHH-90L2-2 – a three-phase industrial motor rated at 2.2 kilowatts for pumps, extraction systems and simple machine drives
Motors such as the AEHH-90L2-2 described here belong to the broad class of small to medium three-phase industrial motors, working on pumps, fans and light machine drives across trades and industry.

The motor produces 2.2 kilowatts, an output common in workshops and small operations for pumps, extraction systems or simple machine drives. The figure 90 in the designation points to a small, common frame size under IEC 60072 that fixes the shaft centre height and mounting dimensions.
In industrial motors of this kind the squirrel-cage rotor is standard, since it runs with little maintenance and needs no slip rings. The number of poles sets the synchronous speed: at 50 hertz, two-pole motors turn at 3,000 revolutions per minute, four-pole motors at 1,500 and six-pole motors at 1,000, each slightly reduced by slip. Protection ratings follow IEC 60529 and mounting arrangements IEC 60034-7, for example a foot-mounted IM B3 motor or a flange-mounted IM B5 type. Running it from a frequency inverter raises the demands on insulation strength.
When buying secondhand, the rating plate is worth checking first: output, voltage, frequency and connection type should be legible and suitable. Turned by hand, the bearings should run smoothly, without play or noise, while an insulation test with an insulation-resistance tester reveals damp or damaged windings. The fan cover and terminal box deserve a second look, since corrosion or broken ribs point to a hard working life. If the motor has been rewound, that is worth raising openly before buying.

Frequently asked questions
How much power does the Kuo Shay AEHH-90L2-2 have?
The Kuo Shay AEHH-90L2-2 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.
