AMA Aluminium Motor

AMA-IE2 Aluminium multi-mount motor


This range of aluminium IE2 high efficiency multi-mount motors are suitable for many different industrial applications, including fans and pumps. The multi-mount design enables the feet to be removed or moved to provide left, right or top terminal box configurations.

The European directive 98/34/EC calls for the introduction of IE2 motors from June 16th 2011 and IE3 motors from January 1st 2015.

IE2 = High efficiency (originally EFF1).

Main specifications:

All AMA-IE2 motors are manufactured in accordance with IEC 34-1/9
The bearings are maintenance free lubricated with lithium-based grease
Motors are fitted with V-seals
Windings are vacuum pressure impregnated and made of high quality insulated wire and insulation material. The impregnation is a evaporation free process, suitable for tropical climate zones.The rotors are dynamically balanced with half key, in accordance with IEC 34-14, class N (Normal).
Overload capability, in compliance with IEC 34, 1.5 times the rated current for 2 minutes and 1.6 times the rated torque for 15 seconds.
Mounting is available in B3, B5, B14S, B14L, B35, B34S and B34L.
