EMS Other models

The register lists here 59 versions with 0.75 to 55 kW, two- to eight-pole, full-load efficiencies from 70.93 to 93% and at 75% load from 70.45 to 94%. Frame sizes run from 80 to 250, all motors are recorded with IP55 protection and mounting code B3/B5/B35/B14. China is recorded throughout as the manufacturing country. Testing followed the older 2000 Legacy AS/NZS 1359.5 standard throughout, with test method B; of 59 motors, 5 reach the 2001 High Efficiency Level and 1 both classifications, 53 stay unclassified.

Limited to frame sizes up to 250 and outputs up to 55 kW, EMS covers the lower to mid segment of classic standard motors, used mainly in pumps, fans and general drive tasks.

When buying used, what matters is bearing condition and a checked insulation resistance of the winding, visible corrosion on the terminal box and fan cover, the condition of shaft and key, and a legible nameplate with frame size and pole count; since almost the entire range is registered under the older Legacy standard, inverter suitability should be checked before variable-speed operation. Spares and support depend on the distribution channel.
