Glong lists the HMS90S-4 as a three-phase induction motor. The rated output is 1.1 kW. The motor is four-pole, which at 50 Hz gives a synchronous speed of 1,500 rpm. The housing is frame size 90 S in foot-mounted form. The protection class is IP54 and IP55. The efficiency is 84.3 per cent at full load, 84.4 per cent at 75 per cent load and 82.2 per cent at half load. The motor is built in China. The figures come from the Australian MEPS register under the GEMS Determination 2019; measured to IEC 60034-2-1 (Edition 2.0). Rated output across the Glong range ranges from 0.75 to 7.5 kW; the HMS90S-4 sits at the bottom of that range with 1.1 kW. Its immediate neighbours are the HMS802-4 below it with 0.75 kW and the EMS112L2-2 above it with 7.5 kW. 3 Glong models are on record.

Glong – other models: the collective page of MEPS-registered three-phase motors outside the named ranges, EMS and HMS series from China, 0.75 to 7.5 kW, two- to four-pole

This page gathers the Glong three-phase motors the Australian energy-efficiency register could not assign to a named range. The types recorded in the register, EMS112L2-2, HMS802-4 and HMS90S-4, come from two of the maker's ranges, EMS and HMS, with the frame size in the middle digits and the pole count at the end of the designation.

The register lists here 3 versions with 0.75 to 7.5 kW, two- to four-pole, with full-load efficiencies from 83.28 to 88.47% and at 75% load from 83.39 to 88.9%. Protection is IP54 and IP55, frame size runs from 80 to 112. China is recorded as the manufacturing country; testing followed the 2019 and 2012 GEMS determinations with test methods B and A; none of the three motors reaches a High Efficiency classification under GEMS.

Motors in this span from under 1 to 7.5 kW cover a wide field from small fan drives to pumps in commercial use; registration under the Australian GEMS standard shows that Glong certifies its range for the Australian market too.

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 and pole count; anyone wanting to run the motor on a variable-speed drive should check its inverter suitability beforehand. Spares run through Glong's sales channel.

The Glong HMS90S-4 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.
